Sorry for the late response. The problem was with the computer's IP Address, so the PC and PLC were not connected correctly. Thank you very much for your help!

Support Questions / No Response from PLC

« on: May 19, 2020, 01:19:41 PM »

Hello everyone. I just started using AHMI yesterday and the software is still a bit confusing to me. I tried looking through some old posts for the solution to the problem I am having but I could not find anything that resolved the issue, so I thought I might ask it here.

I am using a CompactLogix PLC and I am trying to read data from an IO Module connected to the PLC. The tags for the IO Module appear under the Controller Scope tags. In order to test that everything was working correctly, I decided to make a simple application to display one of the IO values on a Digital Panel Meter. To do this, I built the solution, added an EthernetIPforCLX driver, selected the appropriate IP address, added a Digital Panel Meter display, and typed the name of the tag (Local:1:I.Ch5Data) into the PLCAddressValue parameter. However, whenever I run the application, the Digital Panel Meter's value never changes and the words "No response from PLC 192.168.1.17, slot=0" appear across the top of the Digital Panel Meter display. I checked and I am pretty sure I am using the correct IP address and slot number.

In one of the posts I read, it suggested that RSLinx.exe must not be running in order for the application to work. However, when I attempt to stop RSLinx.exe in the task manager, Studio 5000 also crashes. I would really appreciate any help I can get regarding the issues I have outlined above. I have included three screenshots that I hope might help.
