While working on a development server with a development PLC connected, when I try to write to tags int he PLC I get an error, “Error writing to OK.value: Bad”. There is another PLC connected to this system as well. Both are Allen-Bradley ControlLogix processors. The second PLC I can write to.
We have swapped the PLC for which the errors are generated and still get the error.
Attached is the configuration, status, and other information relevant to this connection and errors.
The device configuration is all default with exception of the name and the IP address.
I have not seen this before and I’ve used quite a few ControlLogix processors with Ignition.
This particular PLC is a v31.01 version processor.
Can anyone shed some light on what may be going on here?
