Pointe Controller User Guide 2.1 Chapter 2: Initial Setup Getting to Know the Pointe Controller Base The figure below shows the layout of a Pointe Controller base: The Pointe Controller base consists of a card cage containing the motherboard. The base unit has a built in Ethernet port, as well as an RS232 port. The Ethernet port is the interface to the larger system. The RS232 port is provided for general purpose communications (as defined by your application program).
Chapter 2: Initial Setup 2.2 Pointe Controller User Guide Supplying Power to the Pointe Controller The Pointe Controller unit requires a 8-30VDC, 1 Amp power supply. This can be provided either by using a wall-pluggable AC adapter (part number OL-PS1) or by connecting the unit directly to a properly rated DC grid. The connection is made at the Power Input screw terminals located at the bottom left corner of the base unit. To connect a power supply to the controller: 1.
Pointe Controller User Guide 2.3 Chapter 2: Initial Setup Installing the PointeControl Software The PointeControl software CD (part number NS-PTC) includes the control application development package and the various utilities needed to connect to and configure the Pointe Controller unit. System requirements: 200 MHz or faster Pentium processor Operating system (any one): o Microsoft Windows NT 4.
Chapter 2: Initial Setup 2.4 Pointe Controller User Guide Configuring the Controller’s Network Settings Each Pointe Controller unit has two distinct addresses: an IP address, for communicating across an Ethernet network; and a Modbus address, for communicating with serial Modbus devices such as operator panels and bar code readers. In this initial setup, we will configure only the IP address. The Pointe Controller unit comes preconfigured with a default IP address.
Pointe Controller User Guide Chapter 2: Initial Setup The PointeControl/OptiLogic Update Tool application window appears. 4. Click Automatic Base Detection. The application should immediately connect to your Pointe Controller unit. If it does not, check your serial connection and try again.

For the Node Name pane, enter the name by which the Pointe Controller unit will identify itself to PointeControl Monitor. For example, “Gundam.” NOTE: If you do not want or need to change the Node Name, you can skip this step and leave the factory default setting.
Chapter 2: Initial Setup 2.5 Pointe Controller User Guide Installing I/O Modules in the Controller Each module occupies one slot in the controller base. Each slot position is numbered as shown below. The slot number will provide a reference to your application program for selecting the appropriate module for each particular operation. Slot numbering is simply left to right, starting with slot number 0. Each slot has card guides along each side and a connector on the motherboard.
Pointe Controller User Guide 2.6 Chapter 2: Initial Setup Connecting the Controller to Your PC An Ethernet network connection is used to download finished control applications from your PC to the Pointe Controller unit. It is also used to monitor the unit's runtime performance and to share Modbus TCP data between different control devices. An RJ-45 Ethernet port is located at the left side of the Pointe Controller unit. The simplest system is a point-to-point connection.
Chapter 3: Quickstart Project Pointe Controller User Guide Chapter 3: Quickstart Project The first project we will implement with the Pointe Controller is a very simple one that involves setting up an automated timer and then adding a few different types of indicators that can be used to display the progress of the timer. To implement this project, you will need the following.
Pointe Controller User Guide 3.1 Chapter 3: Quickstart Project Starting a New Project Begin by launching the PointeControl Framework application and creating a new project: 1. From the Windows Start menu, choose Programs > PointeControl > Framework. The PointeControl Framework window will appear. 2. From the File menu, choose New Project. 3. In the New Project dialog box, enter the name of your project (e.g. “Mytest”) and click OK. Once you have done this, your new project will be opened.
Chapter 3: Quickstart Project 3.2 Pointe Controller User Guide Defining Input, Output, and Memory Tags The next thing that we’ll do is define our inputs, outputs and memory tags that we’ll need for this project. In general, you can do I/O and data memory definitions piecemeal, throughout the project development process – whenever you find you need another variable or I/O point.
Pointe Controller User Guide Chapter 3: Quickstart Project 2. Create a table entry for the first input tag (%IX1), either by clicking the Insert button or by incrementing the Size counter up to 1. 3. In the Alias field, enter the name of the input tag: InSwitch1. (You will need to click in the field before you can type in it.) Now go ahead and define the rest of the tag names for the input module, even though we’re not going to use them in this tutorial project.
Chapter 3: Quickstart Project Pointe Controller User Guide 4. Click the Copy button. The Copy Channels dialog box will appear. 5. Increment the Number of channels up to 7 and click OK. Seven more input tags will be defined in numerical order, copied from the original InSwitch. 6. Close the input tag editor window using the When asked to save changes, click Yes. 3.2.2 button in the corner.
Pointe Controller User Guide Chapter 3: Quickstart Project 3. In the Alias field, enter the name of the output tag: Myout1. You will need to click in the field before you can type in it. 4. Click the Copy button. The Copy Channels dialog box will appear. 5. Increment the Number of channels up to 7 and click OK. Seven more input tags will be defined in numerical order, copied from the original Myout. 6. Close the output tag editor window using the When asked to save changes, click Yes. 3.2.
Chapter 3: Quickstart Project 3.3 Pointe Controller User Guide Associating Tags with I/O Points At this point, we have tag-names defined. However, we haven’t configured our I/O and haven’t associated our tag-names with particular I/O points. Let’s do that now: 1. From the Project menu, choose Configure I/O. The I/O Configuration window will appear. 2. Next to Slot 1 module type, click the drop-down menu and select OL2201. This configures the OL2201 module in slot 1 of the Pointe Controller base unit.
Pointe Controller User Guide Chapter 3: Quickstart Project NOTE: Configuring slot 1 activates the I/O button to the right of the slot. 3. Click the I/O button for slot 1. The OL2201 I/O Map window will appear. At this point of our project development, we have defined input tag names and selected an input module. What we haven’t done is associate each input tag name with a particular point on the input module. That is what we will do now. 4. To the right of Input 1, click the will appear. button.
Chapter 3: Quickstart Project Pointe Controller User Guide 7. Click OK to close the OL2201 I/O Map window. Now repeat the procedure to associate the eight output tags with the OL2109 module in slot 2: 8. Next to Slot 2 module type, click the drop-down menu and select OL2109. This configures the OL2109 module in slot 2 of the Pointe Controller base unit. 9. Click the I/O button for slot 2. The OL2109 I/O Map window will appear. 10. To the right of Output 1, click the tags will appear. button.
Pointe Controller User Guide Chapter 3: Quickstart Project 12. Repeat steps 10 and 11 for each of the remaining seven outputs, associating MyOut2 to Output 2, MyOut3 to Output 3, and so on. 13. Click OK to close the OL2109 I/O Map window. 14. Click OK to close the I/O Configuration window.
Chapter 3: Quickstart Project 3.4 Pointe Controller User Guide Creating Your First Flow Chart We’re going to do our first application with a flow chart. To create a new flow chart: 1. In the project workspace window on the left, select Flow Chart. Then from the File menu, choose New. When you do this, a new flow chart will be created and added to the project tree.
Pointe Controller User Guide Chapter 3: Quickstart Project We could give our flow chart a name right now. In most cases, you would immediately name your flow chart based on the function it performs in your application. Typical names include “Gantry 1,” “IPA Tank,” “Purge Cycle,” and so on. We’re going to wait to give our program a name and use the default name “Chart1” for right now.
Chapter 3: Quickstart Project Pointe Controller User Guide 3. Double-click on the decision block to open its associated Block Properties window. The Block Properties window is where you define what the block will do. As you can see, there are a number of properties that you can configure. Caption determines the text description of the block. This is useful in documenting the project, but we shall leave it unchanged for now and come back to it later.
Pointe Controller User Guide Chapter 3: Quickstart Project When the property is changed, the Then and Else paths are switched. Timeout Value is an optional override that we won’t use here. Condition Type is an Expression (the default). We want to define our expression as “If InSwitch1 = ON”: 5. To the right of the Expression property, click the Condition window will appear. button. The Build 6. In the Arg Type list on the left, select Inputs. A list of available inputs will appear under Selection List.
Chapter 3: Quickstart Project Pointe Controller User Guide 8. Click the = button to add “=” to the condition. 9. Click the ON button to add “ON” to the condition. 10. Click OK to close the Build Condition window and enter the condition in the Expression property. 11. Close the Block Properties window.
Pointe Controller User Guide 3.5 Chapter 3: Quickstart Project Inserting a Second Decision Block So far, all we’ve done is check to see if InputSwitch1 is on. If it is on, we want to flash the first two output LEDs out of phase. To do so, we turn the first output on and the second off for a period of time, then turn the first output off and the second on for a time period. Our flow chart will use the flag that we previously defined, rightOn, to keep track of which state we are in. 1.
Chapter 3: Quickstart Project 3.6 Pointe Controller User Guide Assigning Outputs Now we are going to add the first of the two output patterns — turn off the first output LED (MyOut1) and turn on the second output LED (MyOut2). 1. Click the Process Block tool on the toolbar, and then click on the Then branch below your “rightON = TRUE” decision block. A new Process block will be inserted. 2. Open the Process block’s Block Properties window, as described previously. 3.
Pointe Controller User Guide Chapter 3: Quickstart Project 10. Move the cursor to the Expression field, either by clicking in it or by pressing the Tab key. 11. Click the OFF button to add “OFF” to the expression. 12. Click OK to close the Build Assignment window and enter the assigment in the Statement sub-property. 13. Now let’s add a second Assign command to this same Process block.
Chapter 3: Quickstart Project Pointe Controller User Guide 14. Click on and highlight the existing Command property, and then click the Insert button. A second Command property will be inserted. 15. Define the second Command property as “MyOut2 = ON,” as described previously. Now we have two Assign commands in the Process block, as shown below.
Pointe Controller User Guide Chapter 3: Quickstart Project Let’s add just one more statement to set rightOn to TRUE. This will force the decision block to take the other branch on the next scan through. In that branch, we’ll set the output states to the opposite values. That will create the flashing effect that we are looking to achieve. 16. Insert a third Command property, as described previously. 17. Define the third Command property as “rightOn = TRUE,” as described previously.
Chapter 3: Quickstart Project Pointe Controller User Guide The Process block should appear as shown below. 22. Close the Block Properties window. Looking at our flow chart, we can now see that if the toggle switch (InSwitch1) is on, then the output LEDs (MyOut1 and MyOut2) will flash back and forth. As soon as the chart reaches the end, it returns to the start and scans through again. If the toggle switch is off, then the output LEDs freeze in their last state until the switch is on again.
Pointe Controller User Guide 3.7 Chapter 3: Quickstart Project Adding a Time Delay Unfortunately, when the toggle switch is on, the output LEDs flash too rapidly for us to see. We need to put in a time delay of 500 milliseconds — just enough to slow the flashing to an observable speed. 1. Insert a new Process block after the two Process blocks that you defined earlier. NOTE: If you place the block in the wrong place, there are two ways to fix it.
Chapter 3: Quickstart Project Pointe Controller User Guide 5. In the Argument field, enter a numerical value of 500. 6. Click OK to close the Build Argument window and enter the argument in the Wait Value sub-property. 7. Close the Block Properties window. Your flow chart should now appear as shown below.
Pointe Controller User Guide 3.8 Chapter 3: Quickstart Project Checking the Chart Integrity The final step in entry, or modification, of a flow chart is an integrity check. This integrity check will automatically check the chart for errors in the flow chart function blocks. It will not tell you if your flow chart logic is correct – it will only tell you if the statements have been entered properly. To perform an integrity check, click the Check Integrity tool on the toolbar.
Chapter 3: Quickstart Project 3.9 Pointe Controller User Guide Building the Project Runtime Once all of the flow charts have been created, we are ready to build the project runtime. First, we must define the list of charts that make up the project. A project can be comprised of many flow charts and/or ladder diagrams. When a chart is created, it is not automatically added to the project list. This allows you to incrementally edit charts and keep optional charts within your development environment.
Pointe Controller User Guide Chapter 3: Quickstart Project The result should be as shown on the right. 3. Click OK to close the Chart List window. After you have configured the project’s chart list, you must define the scan parameters. Your project’s runtime operation actually occurs in a repetitive cycle of updating inputs, logic solve, updating outputs and communications. 4. From the Edit menu, choose Preferences. The Preferences window will appear.
Chapter 3: Quickstart Project Pointe Controller User Guide Controller Timeout Interval is a watchdog timer for the chart execution. If the chart logic solve is greater than this value the project will stop. Download Source when checked will send the project source code to the Pointe Controller. If this is un-checked the source will not be present in the Pointe Controller and the Pointe Control Monitor will not be able to view or debug the application.
Pointe Controller User Guide Chapter 3: Quickstart Project 3.10 Downloading and Running Your Program Downloading a finished program to the Pointe Controller unit is performed via the PointeControl Monitor. The Monitor is launched separately from the development framework, either by choosing it from the Windows Start menu (Start > Programs > PointeControl > Monitor), or by “activating” it from within the framework itself.
Chapter 3: Quickstart Project Pointe Controller User Guide Once the PointeControl Monitor window is active, you can download your project runtime to the Pointe Controller unit: 1. Click the Controller drop-down menu and select the Pointe Controller unit from the listed devices. 2. Click the Project drop-down menu and select your project runtime. If you have followed the examples given in the quickstart, your project runtime should be named “Mytest.” 3. Click the Load button.
Pointe Controller User Guide Chapter 3: Quickstart Project Controller’s Java-based processor. In most cases you can ignore these messages; they are useful only when troubleshooting a faulty download. A progress bar in the Pointe Control Monitor window shows your project runtime is downloaded to the Pointe Controller unit.
Chapter 3: Quickstart Project Pointe Controller User Guide When the download is complete, the Start button will become active. 4. Click the Start button to run the project. 5. Select the Charts tab, as shown below. The PointeControl Monitor window should show that your one chart (as configured in the Chart List) is running. The Pointe Controller unit is now executing your project as a real-time control progam.
Pointe Controller User Guide Chapter 3: Quickstart Project 3.11 Monitoring Your Program While It Runs From your PC, you can monitor logic flow, view snapshots of tag values, change tag values, set breakpoints, single-step through your program, and get performance and loading information. To monitor your program while it is running: 1. In the PointeControl Monitor window, click the Charts tab. A list of all currently running charts will be displayed. 2. In the Charts tab, double-click Chart1.
Chapter 3: Quickstart Project Pointe Controller User Guide 3. In the Chart1 monitor/debug window, click the Enable Logic Flow and Enable Debug Trace tools on the toolbar. You now have a snapshot of the program’s logic flow, highlighted in yellow and updated at a regular interval. The logic flow shown is the last 200 program blocks executed each time the monitor collects a snapshot. The snapshot is taken based on the Monitor update interval that you defined previously.
Pointe Controller User Guide Chapter 3: Quickstart Project 4. Double-click on any of the flow chart blocks (except the Start and Stop blocks). A Block Watch window for that block will appear, showing all of the tags referenced by that block. The Block Watch window shows all of the tags used in the block and the running value of each tag. NOTE: The value shown for each tag is not the real-time value of the tag as the Pointe Controller is actually executing the block.
Chapter 3: Quickstart Project Pointe Controller User Guide 3.12 Setting Breakpoints Sometimes you’ll want to check if your program gets to a particular point in your chart. You may also want to step through the execution of the program one block at a time in order to debug your logic. This is achieved by setting break points in the logic flow: 1. Make sure your program is running and Debug Trace is enabled. (See “Monitoring Your Program” above.) 2. Select a block in the flow chart.
Pointe Controller User Guide Chapter 3: Quickstart Project When you do this, an alert window will pop up on your screen, warning you that stopping the flow of a running program could cause problems (if you were actually controlling a machine) and asking you to verify that you do in fact want to insert the break point. 4. Click Yes. A break point will be set on the selected block.
Chapter 3: Quickstart Project Pointe Controller User Guide indicates that a break point is set for this block. The red diamond indicates that the program has hit the break point. Now that we have hit a break point, we can step through the program one block at a time: 5. Click the Single Step tool on the toolbar.
Pointe Controller User Guide Chapter 3: Quickstart Project 6. Continue to click the Single Step tool and watch the Pointe Controller step through your program. Each time you click the Single Step tool, the program will step to and highlight the next block in the flow. All blocks will execute as they normally would, updating tag values and changing outputs as they go. NOTE: You may wish to disable Debug Trace as you step through the program, in order to reduce screen clutter.
Chapter 4: System Design and Installation Pointe Controller User Guide Chapter 4: System Design and Installation Now that you understand the basics of the Pointe Controller, you can design a complete machine control system using it. Good system design includes defining your I/O needs, selecting the appropriate modules and panels, calculating the power budget of the system, wiring the I/O to the equipment, and observing proper safety guidelines.

(Optimation is a wholly-owned subsidiary of Nematron.) OptiLogic components can be plugged together in nearly any combination. This chapter covers the currently available modules that plug into the card cage.
Chapter 4: System Design and Installation 4.6.1 Pointe Controller User Guide Digital Inputs Digital I/O modules are used to either monitor (input) or control (output) the “state” of something. “State” being on or off, active or inactive, open or closed — etc. In the “real world” digital I/O requirements come in a variety of shapes and sizes. Therefore, there are a variety of available modules designed to meet the variety of needs.
Pointe Controller User Guide Chapter 4: System Design and Installation Typical DC digital input circuits are shown below: As shown, the physical optical emitter on the input module is an LED (light emitting diode). OptiLogic DC inputs use bidirectional LEDs — i.e. Your inputs may either source or sink current. The top figure shows a sourcing input. The figure below it shows a sinking input. When inputs are connected to a “common” (most instances), inputs must be either all sourcing or all sinking.
Chapter 4: System Design and Installation Pointe Controller User Guide Digital Input Voltage Any digital input module, AC or DC, is designed to operate within an input voltage range. The input voltage directly controls the amount of current flowing through the circuit. The minimum voltage corresponds to a voltage that creates enough current to produce LED light sufficient to be sensed by the optical sensor.
Pointe Controller User Guide 4.6.2 Chapter 4: System Design and Installation Digital Outputs Digital outputs are used to turn “loads” on and off. “Loads” may be lights, motors, solenoids, or any type of on/off device found in the “real world.” Digital outputs in the OptiLogic series come in three types — relay, transistor and solid state relay. Each type has applications it is best suited for.
Chapter 4: System Design and Installation Pointe Controller User Guide When the contact is closed, the diode is reverse biased and no current flows through it. When the contact opens, current will continue to flow through the inductive load. The diode provides a path for current flow. The result that is the energy is dissipated in the inductive coil and not the relay contact. NOTE: Do not use this circuit for AC loads. Transistor Outputs An NPN transistor sinking output provides a path to ground.
Pointe Controller User Guide Chapter 4: System Design and Installation Solid State Relay Outputs Solid state relays are semiconductor switches that operate very much like mechanical relays. They have an advantage over mechanical relays by virtue of the fact that they are semiconductors. Solid state relays can be switched at relatively high frequencies and they do not wear out. However they are more expensive and there is a small voltage drop across the contact.
Chapter 4: System Design and Installation Pointe Controller User Guide via a switching power converter and a transformer. There are OptiLogic analog input modules in both categories. Neither is functionally superior to the other. The on-board power generation may save the cost of an additional external power supply.
Pointe Controller User Guide Chapter 4: System Design and Installation Accuracy Accuracy is expressed as the worst case deviation from the “ideal value” across the entire input range. For example, for a 0 to 5V input range and a 12-bit A/D module, a 2.0 volt input should yield a value equal to 1638 (0.4 x 4096). If it returns a value of 1636, and this is the worst case error across the entire range of 0 to 5V, the accuracy is 12 bits +/- 2 counts.
Chapter 4: System Design and Installation Pointe Controller User Guide In order to use single ended inputs, the ground connection must be very good. The measurement devices must also be capable of being referenced to a common ground. Differential Inputs There are cases when the individual analog inputs cannot be connected to a common ground. In those cases, a differential input A/D converter should be used.
Pointe Controller User Guide 4.7 Chapter 4: System Design and Installation Determining Your I/O Needs The Pointe Controller system offers the following ways to add I/O to the system: Local I/O – consists of I/O modules installed in the Pointe Controller unit itself. Remote I/O – consists of I/O modules installed in OptiLogic RTU bases connected to the Pointe Controller unit through the Ethernet network.

Chapter 4: System Design and Installation 4.8 Pointe Controller User Guide Installing I/O Modules in the Controller Each Pointe Controller application will differ in the number and type of I/O modules, the operator panels used (if any) and how the devices must be distributed. The modular design of the Pointe Controller system allows you to mix and match to meet your exact application requirements.
Pointe Controller User Guide 4.8.2 Chapter 4: System Design and Installation Installing Modules Each slot has card guides along each side and a connector on the motherboard. To install an I/O module, place the module’s circuitry board in the top and bottom card guides. (Note that the board will not be tightly retained until it is approximately 3⁄4 inch into the card guide.) As you push the module into its mating connector, squeeze the ends together.
Chapter 4: System Design and Installation 4.9 Pointe Controller User Guide Mounting the Pointe Controller Pointe Controller units are intended to be mounted on a standard DIN rail. That DIN rail can be a commercial DIN rail attached to any flat surface. It can also be the DIN rail built into OptiLogic operator panels. 4.9.1 Mounting the Base on a DIN Rail A DIN rail is simply a standard “U” shaped channel which is designed to be mounted horizontally on any flat surface.
Pointe Controller User Guide Chapter 4: System Design and Installation Now, take a look at the bottom side of the controller base. It will appear as shown below: The DIN rail channel runs lengthwise across the middle of the base’s bottom side. At the top of that channel are three overhanging hooks. At the bottom of the channel there is a sliding retaining clip. The process of installing a base on a DIN rail is as follows: 1. Pull the retaining clip back from the center of the base.
Chapter 4: System Design and Installation Pointe Controller User Guide The mounting process is exactly the same as described for mounting to a DIN rail. Be sure that your orientation is right so the connectors on the base and the front panel line up. An Pointe Controller unit base attached to an OptiLogic operator panel should look like the figure below.
Pointe Controller User Guide Chapter 4: System Design and Installation 4.10 Connecting the Controller to Your Network An Ethernet network connection is used to download finished control applications from your PC to the Pointe Controller unit. It is also used to monitor the unit's runtime performance and to share Modbus TCP data between different control devices. An RJ-45 Ethernet port is located at the left side of the Pointe Controller unit.
Chapter 4: System Design and Installation Pointe Controller User Guide 4.10.2 Single Hub and Switched Connections The next level of complexity is a single hub or switch system. Hubs and switches are commonly available with anywhere from 4 to 24 connections. The multiple Ethernet ports on a hub allow physical star type network wiring. The hub is typically placed in the center of the system. Individual cables are run between the hub and each controller. Crossovers are made internal to the hub.
Pointe Controller User Guide Chapter 4: System Design and Installation 4.11 Ethernet Connection Guide Ethernet 10Base-T is a flexible, low cost method of cabling local area networks. Pointe Controller units must be connected using 10Base-T compatible products. All Ethernet 10Base-T implementation details are defined by the EIA/TIA standard 568A. This standard specifies UTP, an acronym for Unshielded Twisted Pair cable, to be between all nodes on a given 10Base-T network.
Chapter 4: System Design and Installation Pointe Controller User Guide 4.11.3 10Base-T Connections Most hardware ports on Ethernet 10Base-T equipment are wired MDI-X (meaning medium dependent interface crossover) so you can use straight-through cable for interconnecting the network devices. This allows for proper alignment of transmitter and receiver circuits according to 10Base-T networking standards. For hub-to-hub connections, a crossover type cable is commonly required.
Pointe Controller User Guide Chapter 5: Developing Controller Programs Chapter 5: Developing Controller Programs Once you have your machine control system designed and your I/O selected and installed, you can proceed with developing the control program itself.

Chapter 5: Developing Controller Programs 5.7.3 Pointe Controller User Guide Condition (If/Then/Else) Block A Condition block contains a Yes or No type question that directs program flow in one of two directions. When the specified condition evaluates to a non-zero value, program flow proceeds down the true branch. By default, the true branch is labeled “Then” and the false branch is labeled “Else,” to correspond to the if-then-else programming construct.
Pointe Controller User Guide Chapter 5: Developing Controller Programs Condition Block Example This decision block determines if Input_1 is ON or OFF. If Input_1 is ON, program flow continues through the Flowline labeled Then. If Input_1 is OFF, flow continues through the flowline labeled Else. The LineLabels property specifies a Then label for the flowline followed from a true or on condition and an Else label for the flowline followed from a false or off condition.
Chapter 5: Developing Controller Programs 5.7.4 Pointe Controller User Guide Repeat/Until Loop Block The Repeat/Until Loop block represents a repetitive process, where the block checks the condition at the bottom of the loop, ensuring that the chart executes the sequence of instructions at least once. If the condition at the bottom of the loop is true, program flow continues at the next block in the chart. If the condition is false, control returns to the top of the loop.
Pointe Controller User Guide Chapter 5: Developing Controller Programs yes, program flow continues through the Flowline labeled Done. If Input_2 is less than 20, flow yields to the next chart, then returns to the flowline Repeat to again increment and check Input_2 until the required count is reached. 5.7.
Chapter 5: Developing Controller Programs Pointe Controller User Guide PROPERTY WHAT YOU ENTER Condition Type Type of Condition: Expression – Build a conditional expression using the Build Condition dialog. Diag Fault Bit Test – Select an Input, Memory, or Output tag and test to see if its Diag Fault Bit is set or clear. If the condition evaluates true, then the Do/On line is followed. If the condition evaluates false, then the Done/Off line is followed.
Pointe Controller User Guide 5.7.6 Chapter 5: Developing Controller Programs Subchart Block A Subchart block makes a call to a previously defined subchart, analogous to a call to a subroutine in a programming language. When program flow reaches a Subchart block, the chart transfers program flow to the Start block in the called subchart. Program flow continues from that point until reaching a Return block.
Chapter 5: Developing Controller Programs Pointe Controller User Guide Subchart Example This subchart block calls the function chart, Motion. Program flow enters the block at the top and jumps to the Motion chart’s start block. The subchart block passes each argument, listed in the Block Properties box (Invert becomes ON, Max_Time becomes 100, etc.) to that particular call of the Motion chart. Program flow continues through the Motion chart until reaching a return block.

Appendix C: Ladder Diagram Block Reference Pointe Controller User Guide When EN becomes on, the block function is executed: the Input Value (IN) is converted into an equivalent floating point and the result is sent to the Output Value (OUT). NOTE: When IN is a String, conversion to a numeric representation is attempted. If the conversion succeeds, then OUT is set to 1. If the conversion fails, then OUT is set to 0. The block function is executed every time the ladder is scanned, so long as EN remains on.
Pointe Controller User Guide Appendix C: Ladder Diagram Block Reference Functional Description This block always passes the Enable input state (EN) through to the Enable Out output state (ENO) without change; when EN becomes on, ENO is turned on, and when EN becomes off, ENO is turned off. When EN becomes on, the block function is executed: the Input Value (IN) is converted into an equivalent string and the result is sent to the Output Value (OUT).
Appendix C: Ladder Diagram Block Reference Pointe Controller User Guide C.9.5 Truncate (TRUNC) When used in a Ladder Diagram, the TRUNC block truncates a floating-point input value and discards its fractional (decimal) part. This is effectively the same as rounding the value down to the nearest integer, although the value always remains a floating-point number.
