Setting up ModBus TCP
Hello all, I'm struggling with a ModBus TCP connection, but can't for the life of me understand how to properly set it up. It's my first time doing this but trial and error (and forum reading) haven't worked out so far. I have attached files to make it easier for you to understand and hopefully tell me what I've done wrong.
Basically, I want to access data on another brand PLC via ModBus and create signals for these in my 800xA system to display alarms etc. In between I have a Westermo modem which translates serial modbus to tcp. The IP of the modem is 172.16.27.80
This IP I have currently entered into the Gateway IP address in the hardware tree of the control builder, but I have no idea if this is correct.
The CI867 should have the IP of .81
What am I doing wrong?
Thanks in advance!
