1–6 Overview Required Tools and Equipment The tools and equipment required, depend on if you are using a 1203-GD1 module, 1203-GK1 module, or 1336-GM1 board. 1203-GD1 or 1203-GK1 Module To install and configure a 1203-GD1 module or 1203-GK1 module, you need the following: • Remote I/O communications module (1203-GD1 or 1203-GK1). • 35 x 7.5 mm DIN rail. • Termination resistor(s). • Power source. • 1/8" flathead screwdriver. • Appropriate cables for SCANport and Remote I/O connections.
Chapter 2 Configuring the Module Chapter Objectives Chapter 2 provides instructions and information for configuring the Remote I/O communications module (1203-GD1, 1203-GK1, or 1336-GM1). In this chapter, you will read about the following: • Factory-default settings. • Recording the I/O image table. • Configuring the module. Important: The communications module is not compatible with complementary I/O configurations because it uses both output and input image words for proper product control.
2–2 Configuring the Module Locating the DIP Switches Figure 2.1 SW3.1 = Block Transfer SW3.2 = Logic Command/Status SW3.3 = Reference/Feedback SW3.4 = Datalink A Settings SW3.5 = Datalink B Settings SW3.6 = Datalink C Settings SW3.7 – Datalink D Settings SW3.8 = Truncate Last Datalink Switches on the 1203-GD1 and 1203-GK1 Modules SW2.1 – SW2.2 = Starting Module Group SW2.3 = Last Rack Setting SW2.4 = Hold Last State/Zero Data SW2.5 = Communications Loss SW2.6 = Reset/Program/Test SW1.1 – SW1.
Configuring the Module Factory-Default Settings Quick Configuration 2–3 The module is shipped with the following settings: Feature Block Transfer Logic Command/Status Reference/Feedback Datalinks Switch(es) 3.1 3.2 3.3 3.4 – 3.7 Truncate Last Datalink Starting Group Last Rack Fault Action 3.8 2.1 – 2.2 2.3 2.4 – 2.6 Baud Rate Not Used Rack Address 2.7 – 2.8 1.1 – 1.2 1.3 – 1.
2–4 Configuring the Module Configuring the module As you configure your module, you should complete the I/O image table. First, size the I/O using switch SW3. Next, set the rack address using switch SW1. Finally, select the starting group, last rack setting, fault action, and baud rate using switch SW2. For more information on the I/O image table, refer to the example below and Chapter 4.
Configuring the Module 2–5 Setting Switches on SW3 ! ATTENTION: Injury or equipment damage can result from loss of PLC or Controller Logic Commands (Stop, Start, etc.) when all these conditions are true: • module firmware 3.04 or lower. • 230.4k baud rate. • block transfer is enabled (DIP switch SW3-1 is ON). • block transfers to the module are used (in the ladder program or by DriveTools/DriveTools32 using a Remote I/O pass thru connection). Do not use the 230.
2–6 Configuring the Module Important: Due to an anomaly in firmware release 4.01, Remote I/O modules that are used only for block transfer messages require the following configuration: switches for block transfer and reference/feedback should both be enabled (SW 3.1 and SW 3.3 are ON. SW 3.2 and SW 3.4 through 3.8 are OFF). This configuration prevents a fault on power up. It does not affect rack I/O allocation or the ladder logic program because it still fits within 1/4 rack I/O space.
Configuring the Module Figure 2.5 2–7 Reference/Feedback Switch Off = 0 On = 1 Use SW 3.3 for setting the command I/O To edit the reference/feedback setting, you need to: 1. Refer to the following table to determine the setting for SW 3.3: Reference/Feedback Disabled Enabled SW 3.3 0 1 2. Slide the switch to its appropriate position. 3.
2–8 Configuring the Module Setting Datalinks SW 3.7 through SW 3.4 enable or disable datalinks. A datalink is a type of pointer used by some SCANport products to transfer data to and from a controller. You can use datalinks to change or monitor the value of parameters without using block transfer messages. Each datalink consists of two 16-bit words of input and two 16-bit words of output. You can enable up to four datalinks (eight words in and out).
Configuring the Module Figure 2.7 2–9 Truncate Last Datalink Switch Off = 0 On = 1 Use SW 3.8 for truncating the last datalink. To set the truncate last datalink feature, you need to: 1. Refer to the following table to determine the setting for SW 3.8: Duplicate Message Detection Disable Enable SW 3.8 0 1 2. Slide the switch to its appropriate position. 3. If the switch is enabled, cross out the second module group (word) of the last datalink in your I/O image table on page 2–4.
2–10 Configuring the Module 2. Refer to the following table to set SW 2.2 and SW 2.1: Starting Group 0 2 4 6 SW 2.2 1 0 1 0 SW 2.1 1 1 0 0 3. Slide the switches to their appropriate positions. Settings take effect when a module or board first receives power. When you change a setting, you must remove and then reapply power for the new setting to take effect. Setting the Last Rack Switch SW 2.3 lets you notify a controller that the connected product is the last device with this rack address.
Configuring the Module 2–11 Setting the Fault Action SW 2.6 through SW 2.4 let you configure how a Remote I/O module and connected product act when Remote I/O communications fail (e.g., disconnected cable) or the controller is switched to program or test mode. You can use fault, hold last state, or zero data. If you select hold last state, a product continues in its present state after a communications disruption. If you select zero data, the data output to the product is zeroed.
2–12 Configuring the Module 4. Slide the switches to their appropriate positions. Settings take effect when a module or board first receives power. When you change a setting, you must remove and then reapply power for the new setting to take effect. Setting the Remote I/O Baud Rate SW 2.8 and SW 2.7 set the baud rate at which the Remote I/O module communicates. ! ATTENTION: Injury or equipment damage can result from loss of PLC or Controller Logic Commands (Stop, Start, etc.
Configuring the Module Setting Switches on SW1 2–13 Setting the Rack Address DIP switches 8 through 3 on SW 1 set the rack address for the Remote I/O module. Each Remote I/O device must have a rack address that the controller can recognize. Each rack contains 8 words. Important: When using a PLC-2 family processor, add 1 to the rack number set on the Remote I/O module DIP switches to your PLC code.
2–14 Configuring the Module
Chapter 3 Installing the Module Chapter Objectives Chapter 3 provides the information that you need to install the module (1203-GD1 module, 1203-GK1 module, or 1336-GM1 board).

3–2 Installing the Module Remote I/O Cables Remote I/O communications modules are connected to Remote I/O links with twinaxial cable used for Remote I/O and Data Highway Plus (DH+) communications. When selecting a cable, remember the following: • Only 1770-CD Belden #9463 is tested and approved for RIO and DH+ installations. Using other cables is at your own risk. • The total cable length depends on the baud rate that you are using. Refer to the following table: Baud Rate 57.6 K 115.2 K 230.
Installing the Module Installing a 1203-GD1 or 1203-GK1 Module 3–3 Required Tools and Equipment To install your module, you need the following tools and equipment: • Remote I/O communications module (1203-GD1 or 1203-GK1). • 35 x 7.5 mm DIN rail. • Appropriate cables for SCANport and Remote I/O connections. Refer to the “Selecting Cables” section in this chapter. • Termination resistor (if necessary). Refer to the “Selecting a Termination Resistor” section in this chapter.
3–4 Installing the Module 3. Connect a SCANport cable (1202-Cxx) to a module and product. Important: For the location of the SCANport connector on your product, refer to its user manual. If you are using a port expander, refer to its documentation. Figure 3.2 Connecting the SCANport Cable SCANport Product . Module 4. Connect a Remote I/O cable to the module and link or controller. Figure 3.3 Connecting the Remote I/O Cable PLC Controller Blue Shield Clear .. .
Installing the Module 3–5 5. If the module is the last device on the Remote I/O link, connect the termination resistor. If the Remote I/O link uses 230Kbps, you must use an 82 ohm termination resistor. Figure 3.4 Connecting the Termination Resistor 2 Clear Shield I50 Ohm or 82 Ohm 1 watt +/-10% Sh Blue To Another Remote I/O Link Device 1 6. Connect the power supply to the module. Figure 3.
3–6 Installing the Module Installing a 1336-GM1 Board Required Tools and Equipment To install your 1336-GM1 board, you need the following tools and equipment: • Remote I/O communications board (1336-GM1). • A kit that includes one grounding wrist strap, four Phillips mounting screws, four stand-off nylon headers, and one snap-in comm housing with mounting instructions (supplied with board). • #1 Phillips screwdriver. • Appropriate cable for the Remote I/O connection.
Installing the Module 3–7 4. Screw the four stand-off nylon headers into the appropriate spaces on the drive main control board. Figure 3.6 Mounting the Open Style Communications Board 5. Insert the SCANport connector into the 14-pin SCANport header on the control board. The DIP switches should be facing you. 6. Screw the board securely into place, being careful not to overtighten the four screws. 7. Connect the Remote I/O cable. Figure 3.
3–8 Installing the Module 8. If the module is the last device on the Remote I/O link, either user the internal termination resistor (J2) or an external termination resistor. If the Remote I/O link uses 230Kbps, you must use an external 82 ohm termination resistor. Important: Use only one type of termination (internal or external), Figure 3.
Chapter 4 Creating Ladder Logic Programs Chapter Objectives Chapter 4 provides information about ladder logic programs for products connected to a Remote I/O communications module. In this chapter, you will read about the following: • I/O image table. • Control Features. • Datalinks. • Example ladder logic programs for PLC, SLC, and Logix5550 controllers.
4–2 Creating Ladder Logic Programs DIP switches on SW3 determine how the data contained in the programmable controller I/O image table is used in the drive. Figure 4.1 shows an I/O image table. Figure 4.
Creating Ladder Logic Programs 4–3 Products That Support Datalinks To use datalinks, your SCANport product must support them. Refer to your product user manual. Using Datalinks The following are the rules for using datalinks: • Normally, each enabled datalink reserves two words in both the input and output image tables of the controller. This increases your I/O image size. The starting module group on the module must be set to support the size of the I/O image table.
4–4 Creating Ladder Logic Programs Example Application 2 Another application for datalinks is to set a parameter into a Data Out parameter. The controller input image table word connected to this datalink will then receive the value of the parameter programmed into the Data Out parameter. For example, to monitor the value of parameter 27 in a 1336 PLUS drive, you need to: 1. In the 1336 PLUS drive, set parameter 119 (Data Out A1) to 27. 2. On the module, slide SW 3.4 to ON. See Figure 2.6. 3.

Chapter 5 Using Block Transfer Messages Chapter Objectives Chapter 5 provides information about Block Transfer messages. In this chapter, you will read about the following: • General information on block transfers. • The Remote I/O status word. • Data storage. • Example ladder logic programs using Block Transfer messages. ! ! Understanding Block Transfer ATTENTION: The sample programs and block transfer examples shown in this manual are intended solely for purposes of example.
5–2 Using Block Transfer Messages Understanding the Block Transfer Status Word The block transfer status word is returned from the Remote I/O module. It is the first word associated with the rack in the controller input image table. This status word indicates the condition of the Remote I/O module itself and is not part of the standard block transfer instructions in the ladder program. Figure 5.1 details the individual bits. Figure 5.
Using Block Transfer Messages 5–3 Understanding Data Storage In order to use the block transfer instructions in the ladder program, it is necessary to reserve several words for data storage. Some of these words are required for internal use by the block transfer function, and some contain the block transfer message information. Refer to Appendix B for detailed information on the required data in data files for different block transfer messages. Example PLC Block Transfers Figure 5.3 and Figure 5.
5–4 Using Block Transfer Messages Figure 5.4 Example for a PLC-5/20, PLC-5/40, PLC-5/60, PLC-5/80 This rung performs a Block Transfer Write to the 1203-GD1 at Rack Address 1, Starting Group 0 (the Module number is always 0 with these adatpers). The data instructs the adapter to send a SCANport message. When this message has completed, the response can be read with a BTR.
Using Block Transfer Messages Example SLC Block Transfers 5–5 Figure 5.5 and the following data file illustrate an example block transfer program from an SLC controller to a Remote I/O communications module. This program uses the first block transfer area in the scanner located in the first slot. It also uses data files N10 and B3. The example data file contains the data needed to request a read full of parameter 78. The length of the block transfer data file is loaded into N10:1.
5–6 Using Block Transfer Messages Figure 5.5 SLC Block Transfer Continued When the Gx1 indicates that it is ready for a BTR, this rung sets up the BT buffer for a BTR and enables it. BTR Available I:1.0 Virtual BT.Type Bit 0 = BTW 1 = BTR N10:0 L 7 Virtual BT.EN Bit N10:0 0004 10 1747-SN 15 Virtual BT.EN Bit N10:0 L 15 Virtual BT.
Using Block Transfer Messages 5–7 Calculating the Rack, Group, Slot Address The Rack, Group, Slot address for a block transfer is calculated as shown in the table below. Rack, Group, Slot Address 0,0,0 1,0,0 1,2,0 2,4,0 Decimal Value 0 100 120 240 This value is needed as part of the data file that is copied to the M0-file block transfer buffer in the 1747-SN RIO Scanner module. Example Logix5550 Block Transfers Figure 5.
5–8 Using Block Transfer Messages Figure 5.6 Example for a Logix5550 Due to the asynchronous nature of the ControlLogix platform, input data may change during a program scan. This rung makes a local copy of the Block Transfer Status word to ensure proper synchronization between the ControlLogix program and the RIO Scanner. Make a Local Copy of the 1203-GD1's Block Transfer Status Word MOV Move Source PLUS_IO:I.
