AB CompactLogix & eCatcher

Today we tried to remotely connect to an Allen Bradley CompactLogix PLC and we were not able to make a connection via RSLinx. We used the setup on your web page. https://hmsnetworks.blob.core.windows.net/www/docs/librariesprovider10/downloads-monitored/manuals/application-user-guide/aug-0070-00-en-plc-discovery-through-talk2m.pdf

RsLinx could never see the PLC using the ETHIP driver as shown on page 6. Any idea why we cannot make this work?

Please try the following:

  1. Make sure that the firewall is set to Standard in the Ewon’s Property page in eCatcher.


  1. In RSLinx use the Ethernet (not Ethernet/IP) driver and add the PLC’s IP address to the driver.


You should be able to see the PLC now.
