Hi guys and gals, I have 2 controllers running modbus working perfectly, i need to add another master but for the life of me can't get it working, I currently run the slave and 1st master on socket 3 port 502 over tcp/ip.
I set up a second config rung and assigned it to port 503 on socket 2, have the scan ex on both sockets in the slave and just one on each of the masters. Cant get the second master to take to the slave over socket two. Its frustrating the hell out of me.
Any one point me in the right direction???
Many thanks in advance, Steve
