Where wiring cost is a concern, it may be more cost-effective to distribute I/O points closer to the field devices they control. Field I/O modules can pass I/O data to/from the controller with one single communications link. Terminator field I/O Network Interface Modules offer Ethernet, DeviceNet, or Modbus RTU communication.
The Terminator I/O MODBUS network interface module allows you to connect I/O as a slave station on a MODBUS RTU network.
The T1K-MODBUS can communicate with any MODBUS RTU network master using high-level MODBUS commands.
Some of our DirectLOGIC Programmable Logic Controllers (PLCs) can be used as MODBUS masters, directly through a communication port on the CPU.
(Consult our "PLC Hardware" product category Web site sections or our product catalog for more information).
The T1H-EBC100 module provides a low-cost, high-performance Ethernet link between Terminator I/O and your MODBUS TCP Master, PC-based control or WinPLC/ DL205/ DL405 CPUs using the H*-ERM module for remote I/O.
If you are already using or planning to implement a DeviceNET controller network, our Terminator I/O subsystem will help further reduce the cost of your overall application. We now offer the T1K-DEVNETS (slave) module, which allows our Terminator I/O subsystem to be linked with a DeviceNET master controller.
DeviceNET is a lowcost control network that provides a common method to connect on a single network. This advanced communications media and software is referred to as DeviceNET and significantly reduces hardwiring costs. DeviceNET provides specifications for information exchanged between nodes, such as controller data associated with low-level devices and configuration parameters individually related to system operations.
For use with Think & Do Software, we recommend the SST DeviceNET PCI Master Card, part number 5136-DNPPCI. Recommended cable: Belden 3085A, YR-29832 (or equivalent)
