Hi, we have an old TSX 702 plc, the software is PL7 v3.4 and the comms cable is TSX PCX1031. I am trying to go on line with the plc but I keep getting the message
"Cannot establish the physical link with the plc at address SYS via driver UNTLW01 : the
max. number of addresses available for this terminal has been reached.
Close any other PL7 programs or increase the max. number in the UNITELWAY configuration."
We have other machines with a TSX 702plc so I know its not that. I have no other programs running.
Please advise
