Inconsistent M91 communication issues

Recommended Posts

Hi All,

New to M91, I am struggling with communication issues with VisiLogic. The unit is connected to my laptop by means of programming cable, RJ11=>RS232 adapter and an RS232=>USB prolific adapter.

When I use the remote Access utility, it seems to establish communication. However when trying to use same port/data parameters with VisiLogic, it does not establish communication, whatever I do.


PLC - M91 - 2- R1-R1 OS ver. 3.80

VisiLogic Ver. 9.3.1

updated prolific driver (Win7)

Thanks for your kind help.
