I’ve just started putting a project together and I’m getting a lot of this message in the logs:

ABControlLogixWriteRequest Received (successful) but there is a group number miss match.

Can someone explain what that warning message means? Should I be concerned.

Ignition 7.6.3 talking to a single ControlLogix PLC.

Hi Aidan,

Thanks for pointing that out. I did try a forum search before posting but nothing came up (I was probably putting too much of the error text into the search field).

At least the consensus on your thread seems to be that the message is “harmless”. 😕
