Take a look as our supplier Acromag illustrates how their BusWorks XT Series
Ethernet I/O modules provide a reliable, simple way to
communicate with multiple distant locations.
With Acromag's i2o® peer-to-peer communication on the XT1111 Modbus/TCP discrete I/O module, one signal from the central control room PLC can be split and re-transmitted to many remote sites at the same time.
This document illustrates using Acromag's BusWorks® XT Ethernet I/O modules to split one signal from a central control room PLC and control multiple remote locations using Ethernet protocol.
Defining the Problem:
A customer has multiple remote locations linked over an Ethernet network, each requiring discrete outputs. They all need to be sent the same communication signal at the same time.
System Requirements:
• All remote sites need to be controlled simultaneously from one central control room via Ethernet protocol
Implementing the Solution: | Featured Products: |
| 1. Set up the Ethernet communication between master PLC device and the BusWorks XT discrete I/O modules (XT1111) | • 16-Channel Discrete I/O, Modbus/TCP XT1111-000 |
| 2. Connect the field instruments and verify input status using the software test & polling feature | • 16-Channel Discrete I/O, with Counter/Timers 989EN-4C16 |
| 3. Program the BAS with the remote I/O network parameters and Modbus registers. | • Software Interface Package XT-SIP |
Why Acromag:
Our BusWorks XT Modbus/TCP remote I/O modules include a peer-to-peer feature known as i2o, where two or more slaves can talk to each other without requiring a master. With i2o communication, one signal from the PLC is split by the XT1111 modules and sent to multiple locations. The XT1111 automatically re-transmits the discrete level to each 989EN module's IP address, thus reproducing the status of the original PLC input.
