This is the MODBUS TCP protocol. I have interperted the requested register as 23726. What my problem is, I cannot find anything addressed within the Ignition project to this register.
In my PLC system, this address is not used. It is definitely invalid, but I cannot find what is driving it. It is on a 1 second scan.
I have been away from Ignition for a while and am a bit rusty.
Any input would be appeciated
