i am trying to connect to the serial (modbus) port of a modicon quantum using concept programming package over a telephone line using (dlink) modems at both ends. setting is 2400,7,e,1
used procomm to establish the dialed up connection and then exited - the telephone connection is still maintained but connecting concept to the plc over the serial port gives wrong data - seems the message is garbled. tried different options of parity, rtu model, no. of stop bits - doesn't work.
has anyone done this before.
tried concept since modsoft does not work on win2000!
