vr.sr Posted April 12, 2011 Report Share Posted April 12, 2011 Hi everybody, I have a problem in communication between Z-view and PLC (V130-33-R6). Communication is done via Ethernet, or it should be. I'm using a straight through cable. I managed to ping the PLC successfully, but the port state remains not connected. Later on, after some restarts, port state changed to idle. I made an alias "reading" with address "1;1;MI102", but the question mark on the value remains. For I am using this scada for the first time, maybe there is some catch that is already familiar to someone. In user manual I couln't find the correct syntax for the address, so I'm not sure if 1;1;MI102 is the right one. Any help is appreciated. Thank you in advance, for your effort Quote Link to comment Share on other sites More sharing options...
vr.sr Posted April 13, 2011 Author Report Share Posted April 13, 2011 News! I made the connection, so the post state is CONNECTED. I did in ladder the card int, sock int, plc name, sock connect and scan. Now I have to make SCADA and PLC to talk. Tx is counting, but the Rx and items are 0. Is the port 502 with Modbus on socket 2 condition for their conversation? Quote Link to comment Share on other sites More sharing options...
