How to Communicate with Acromag Ethernet/IP Modules from CompactLogix Controllers – 8500762
Communicating with Acromag Series 9xxEN-60xx, XTxxx2-xxx, and NTE2xxx-xxxx Ethernet/IP™ Modules from CompactLogix™ PLC Device
This document illustrates a procedure for configuring message commands intended for Acromag Busworks® Series Ethernet/IP modules using Ladder Logic programming software in addition to a CompactLogix Programmable Controller. It is assumed that the user has a working knowledge of; Ladder Logic programming and RSLogix5000 software, as well as the CompactLogix hardware.
Configuring I/O Connection in RSLogix5000 to Communicate with Acromag Ethernet/IP Modules from CompactLogix Controllers
- From a new or existing project; right click on the CompactLogix Ethernet controller (shown as 1769-L32E in this example) and select New Module.
- In the Select Module Type box, select Ethernet-Module as shown in the example, and click [OK].
- The Module Properties window should automatically open. Under the Name box, type in the name of the module. In the example below left, the 964EN module is used.
The type of Communication Format used by all modules is Data – INT.
Note: Once the [Finish] button is pressed, the Comm format of the module cannot be changed.
Under the Address / Host Name box; the IP Address must be selected and the IP Address of the module typed in. In the example at left, the IP Address of the module is 188.8.131.52. However, this will vary depending on the address of your CompactLogix controller. See chart in app note for Comm Format, in addition to Connection Parameters.
If you have frequent communication errors or dropouts, consult the BusWorks Manual for the Input Conversion Rate or Output Update Rate; and adjust your PLC RPI rate accordingly. Some units, particularly temperature modules, take up to 480ms to process the inputs; and periodically, another 240ms for cold junction compensation, before RPI’s can be accommodated. In this case, an RPI of 1,000ms is recommended to solve the problem.
