1 Chapter 1: Introduction The Silver Series EM Operator Interface Terminals (OITs) are powerful human machine interfaces for equipment and processes. EZwarePlus 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 Watlow Silver Series EM Installation Guide 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 EM 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: • It can take a few seconds for the Systems settings dialog with the password field to appear.
3 Chapter 3: Communications Basics The Silver Series EM OIT can communicate with Watlow controllers via Modbus TCP or Modbus RTU. This section defines terms you will encounter and provides information about Modbus communications that will help you create a user interface with the Silver Series EM OIT for equipment and machines that include Watlow controllers. About Gateways, Controllers and PLCs The Silver Series EM OIT can communicate with a variety of devices.
supply “the addresses.” So to use any two products together you need to know whether or not you have to convert the specified “address” in order to get the result you want. EZwarePlus’s Modbus drivers call the data block, “Device type” and for “Address” expect the memory location’s absolute address without the data block number. For example, to access a value in a holding register with absolute address 401,905, for Device type you select the data block “4x” and enter “1905” in the Address field.
For example, the EZ-ZONE PM Integrated Controller Models User’s Manual lists Map1 and Map 2 addresses for Process Value for Analog Inputs 1 and 2. If the Data Map parameter is set to Map 1 then the Process Value for Analog Input 2 is read at address 441 (the listed address plus one), but if Data Map is set to Map 2 then the Process Value for Analog Input 2 is read at address 451. The address for the Process Value for Analog Input 1 is the same for Map 1 and Map 2.
ZONE controllers via Ethernet, add three Modbus TCP/IP Master devices to the device list in the System Parameter Settings dialog each configured to communicate with one controller. Addressing Parameters in Multiple Controllers Normally the Silver Series EM OIT assumes that any register address you enter when communicating via Modbus RTU is associated with the controller at the network address you set in the PLC default station no field in the Device Properties under the System Parameter Settings.
In such a system the Silver Series EM OIT is connected to and configured to communicate with the gateway. The gateway presents itself as a single device on the Modbus network; the OIT does not communicate with the controllers, only with the gateway. The gateway is configured by the user with an address offset for each controller connected to it. That address offset is added to the parameter addresses for the controller.

(054) 14) Optional: Use the Scale tool to add a scale and labels with the Text tool. Color coordinate these or add a legend if the trend channels don’t all have the same zero and span.
Use Recipes This example assumes you have a project with at least one controller in which the recipe memory has not already been used for something else. In this example we will create a recipe that has five parameters from one controller. For each parameter we will create a data transfer object that saves the parameter’s value in the recipe in the OIT.
1) From the Objects menu choose Data Transfer (Triggerbased). 2) In Comment type “Recipe Save:” and the name of the name of the parameter (such as “Loop 1 Set Point”. 3) For Source address PLC name choose Modbus RTU Master or Modbus TCP/IP Master. 4) For Source address choose 4x and enter the address of the parameter. 5) In No. of words type word size of the parameter’s data type. 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 MultiState 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. 7) Click OK to close the Address dialog.
17) Click Setting… 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 Mapping window. (070) Note: The first recipe is selected with the multi-state switch in its state 0.
