I’m trying without success to connect to a modbus TCP device (ABB PM554 ETH) using the ignition Modbus TCP driver in ignition 8.
The weird thing is I was able to successfully connect and communicate in ignition 7.9.9.
In ignition 8 it connects and disconnects relative to the OMB time setting on the modbus TCP server.
In the following log pic I had the omb time set at 30,000 ms.
I should note that I saw the same behavior from ignition 7.9.9 when I had the OMB time set at the default 1000 ms…
but upon research found Modbus TCP disconnection and no reconnection [SOLVED] and changing the OMB time to 30000 ms fixed the issue.
I have tried changing the OMB time back to 1000 while attempting to connect to ignition 8 but I get the same error just at a higher frequency.
Anyone else come across this? Any ideas on what to try?
