1 Chapter 1: Overview Features and Benefits Using the RUI as a Gateway Remote user interface (RUI) The addition of a gateway card allows information to be passed from the Standard Bus side of the gateway (EZ-ZONE-family controllers) to one or more of the following popular field bus networks: • Uses one RUI for multiple zones • Shallow panel depth allows it to fit in small spaces • Eliminates the costs and complexity of having to bring all controller related wires to the front panel • Enables the use o

Mounting the Remote User Interface (RUI) 1. Make the panel cutout using the mounting template dimensions in this chapter. Insert the case assembly into the panel cutout. 2. While pressing the case assembly firmly against the panel, slide the mounting collar over the back of the RUI. If the installation does not require an IP66/NEMA 4X seal, slide the mounting collar up to the back of the panel tight enough to eliminate the spacing between the gas ket and the panel. 3.

Failure to do so may result in damage to equipment and property, and/or injury or loss of life. Note: The RUI (remote user interface) without a gateway installed can communicate using Watlow's Standard Bus only. Wiring a Serial EIA-485 Network Do not route network wires with power wires.

5 Chapter 5: Using an RUI/Gateway Conceptual View of the RUI Used as a Gateway: Using Modbus RTU (Communications To/From a Master): As shown in the following network screen shots the gateway allows for connectivity between dissimilar networks.
Modbus Offset 0 gtW 1 = PM1 Modbus Offset 5000 HMI, PC, PLC Com Instance 2 Com Instance 1 Modbus Address Ad;m = 1-247 Standard Bus Address Ad;S = 1-8 Modbus Offset 10000 Baud Rate baud = 9.6, 19.2, 38.
[a;nb] (CIP Assembly Size) Used with implicit messages where this prompt defines the implicit Assembly size. For any given RUI gateway the input and output assembly size will never be greater than 20 members. The user entry ranges from 0 to 20 where all members can be dedicated to one gateway instance or they can be distributed any way the user sees fit across the EZ-ZONE family controllers on the network.
CIP Offset 1-3 CIP Offset 5-7 gtW 1 = PM1 Com Instance 2 Com Instance 1 Standard Bus Address Ad;S = 1-8 CIP Offset 9-11 Start Node to Scan St;2n = 1-16 DeviceNet Node Address Ad;d = 0-63 Network Baud Rate baud = 125, 250.
Using EtherNet/IP™ Using the graphic on the following page as an example, if: (Communications To/From a PLC): [Gtw] instance 1 has [a;nb] set to 5 There are two methods used to communicate to/from a PLC, i.e., implicitly and explicitly. Once the gateway instance is enabled for EtherNet/IP™ there are two prompts that relate directly to these forms of communication shown below. In the explanation below note that it is the CIP offset that is being used not the Modbus offset as shown in the graphic below.
CIP Offset 1-3 Modbus Offset 0 gtW 1 = PM1 Com Instance 2 Com Instance 1 Modbus Word Order M;hl = lohi or hilo Standard Bus Address Ad;S = 1-8 EtherNet Addressing Mode Ip;m = dhCp or F;Add Modbus Enable Mb;e = Yes or No Start Node to Scan St;2n = 1-16 End Zone to Scan nU;2n = 1-16 EtherNet/IP Enable Eip;e = Yes or No EtherNet/IP CIP Offset 9-11 Modbus Offset 10000 Modbus TCP CIP Offset 5-7 Modbus Offset 5000 gtW 4 = PM4 CIP Offset 13-255 Modbus Offset 15000 Watlow Standard Bus (Daisy chain EIA
Saving Settings to Non-volatile Memory When controller settings are entered from the controller front panel or a remote user interface (RUI) changes are always saved to non-volatile memory (EEPROM). If the controller loses power or is switched off its settings will be restored when power is reapplied. The EEPROM will wear out after about 1,000,000 writes, which should not be a problem with changes made from the panel or RUI.
