Hello. I’m having trouble configuring Modbus TCP for the CC100 (751-9301) in CODESYS 3.5.
The firewall is disabled.
In QModMaster, I get a “Connection reset” error, but in the Node.js script, it says the port is closed.
P.S. I’m new to CODESYS.
Screenshots below.
Did you remember to set the IP address of the bridge you want to use in the “Ethernet” device object?
Are you trying to use the CC100 as the Modbus client or the Modbus server? You have both added to your project and your screenshot shows the client information, but I believe QModMaster only acts as a client as well, not a server.
