I’m trying to set up tags using modbus but I can’t connect them. I didn’t have any problems when I setup the devices using Allen Bradley. I thought that maybe the port on the computer is not open so I tried opening the ports manually using the inbound and outbound rules in the windows firewall settings and allowed the port 502 connection but it’s still not connecting.
What else can you guys suggest?
I’m not sure if i should be posting this here but I just want as many answers as I can get.
