1 Chapter 1: Introduction The Silver Series Operator Interface Terminals (OITs) are powerful human machine interfaces for equipment and processes. EasyBuilder5000 is easy-to-use and flexible software for creating the windows, buttons, displays, gauges and other screen items with which operators interact on the OIT. The purpose of this addendum is to quickly get you up and running with the OIT and software when used with Watlow controllers.
2 Chapter 2: Install and Wiring Consult the Silver Series Installation and Operation Manual for detailed information on installing and wiring the OITs. This chapter provides important additional information regarding connecting to and communicating with Watlow controllers. Connecting via Modbus RTU (232/485) The tables below indicate to which pins on the Silver Series OIT’s DB9 connectors the Watlow EZZONE® screw terminals should connect.
• The IP address is listed in the System settings window on the Network tab. (If Auto Get IP Address is selected, the IP Address is not editable. If you want to configure the OIT for a fixed address, select IP address get from below, and enter the IP address here. • Click OK to close the System settings window on the OIT. Hints for using the Virtual Keyboard to enter the OIT password and IP addresses: • If you do not see the Virtual Keyboard it may be minimized; click the X on the menu bar.
Parameter Register Addresses The Modbus RTU and Modbus TCP communications protocols assume that each device’s memory is organized in blocks of like-data. Each data block contains either read-only data or read/write data and either bit-size data or word-size (16-bit) data. For example, the Coils data block contains read/write bits and the Input Register data block contains read-only words. Within each of these data blocks there is a range of memory locations.
For example, the EZ-ZONE PM Integrated Controller Models User’s Manual lists the relative address for Heat Power as 1904. To monitor the heat power with the Silver Series OIT, you will add one (1) to the relative address and enter “1905” in the Address field in EasyBuilder5000. (073) In summary, when setting an address for a screen object to read or write from a Watlow controller: • For the Device type select 4x.
Choosing the Communications Drivers When you create a project using EasyBuilder5000 you select the drivers necessary to communicate with the Watlow controllers and any other devices with which the Silver Series OIT must communicate. For Watlow controllers, you select one of these drivers: • Modbus RTU Master—used with Watlow controllers that support Modbus RTU and communicate via RS-232 or RS-485. • Modbus TCP/IP Master—used with Watlow controllers that support Modbus TCP and communicate via Ethernet.
Address Offsets in Multi-Loop Controllers In controllers with more than one loop of control, more than one limit etc., there is more than one instance of each parameter for these duplicated functions. The manuals for controllers such as the EZZONE RM, list the Modbus address and an offset for these parameters. Add the offset to the address once to get the address of the second instance of the parameter, add it twice to get the third instance and so on.
Data Types The Silver Series OIT’s Modbus drivers support a variety of data types. The Watlow manuals specify the data type of each parameter. However the terminology is not precisely the same. The table below correlates the data types indicated in the Watlow documentation with the data types you should select when configuring a screen object in EasyBuilder5000.

See Table. 6) Click Setting… 7) For Destination address PLC name choose the OIT (Local HMI by default).
11) Click OK to close the Address dialog 12) For Mode choose External Trigger. 13) For Trigger address PLC name choose the OIT (Local HMI by default). 14) For Trigger address Device type choose LB to use an internal bit to cause the OIT to store values in a recipe. 15) In Trigger address Address type 500. 16) Click the Label tab. 17) Check Use label. 18) Set State to 0. 19) In Content type the name of the parameter. 20) Click OK. 21) Place the Data Transfer (Trigger-based) object on the screen.
1) From the Objects menu choose Data Transfer (Triggerbased). 2) In Description type “Recipe Load:” and the name of the parameter (such as “Loop 1 Set Point”). 3) For Source address PLC name choose the OIT. 4) For Source address choose RW and type the recipe address for the item. (062) 5) If you set up the recipe save to use and index register: • Click Source address Settings… • Check Source address Index register • For Source address Index choose INDEX 0 (16-bit). • Click OK to close the Address dialog.
To create a button to trigger the data transfer objects to copy the values currently in the controller to the corresponding recipe memory in the OIT: 1) On the Objects menu, point to Button and choose Set Bit. 2) In Description type “Save Recipe”. 3) For PLC name choose the OIT (Local HMI by default). (063) 4) For Address choose LB and type 500. 5) For Set style Choose Momentary. 6) Click the Label tab. 7) Check Use label. 8) In Content for state 0 type “Save to OIT”. 9) Click OK. 10) Place the button.
Optional: To see what you are copying from the controller to the OIT’s recipe memory, create an object displaying the current value in the controller next to each Data Transfer (Trigger-based) object. Create a label that indicates what the fields are such as “Current Controller Values”. Optional: To see or edit directly what is saved in recipe memory create a data entry object for each recipe item. These objects should display the values of the data in the RW memory at the recipe addresses.
Address indexing allows a screen object to display and set the value of different memory locations depending on the value in the index. In this example we use LW-9200 as the address index. Whatever value the index is set to is added to the address in the data transfer (and recipe display) objects. When the index value is zero, the first recipe is used. When the index is 10 the second recipe is used. When the index is 20 the third recipe is used.
To select the recipe to save to or load from create a multi-state switch to select the recipe as follows: 1) On the Objects menu point to Buttons and choose Multi-State Switch. 2) In Description type “Recipe Selector”. 3) Click Read address Setting… 4) For PLC name choose the OIT (Local HMI by default). 5) Check System tag. 6) For Device type choose LW-9200 (16bit) : address index 0. (069) 7) Click OK to close the Address dialog.
17) Click Set… 18) For each state enter the appropriate offset Value. For state 0 enter 0. For state 1 enter a value that will offset the beginning of the second recipe beyond the end of the first in the recipe memory. 19) Click OK to close the State mapping window. (070) Note: The first recipe is selected with the multi-state switch in its state 0.
