we r using E10 PLC for a small application.
our user needs to monitor the status of all IOs, on PC, and change a timer value in program written in the controller frequently through PC.
We have provided a PC with VB software. Distance between PC and plc is 30 meters.
Hence we r trying to connct PC serial port to 485 port of controller through auto 485. But, we did not get any response from plc when we execute host link commands.
We have tried with 2 baud rates 9600 and 38400 but it did not work.
We also tried using trilogy 3.5 and with VB sample software provided.
But, it works if we use a programing cable with PC serial port.
Is it possible to do 1 to 1 communication (PC and plc) on 485 port for E10?
