can anyone plz help me out to use mvi69mcm module
most of the times i get an error -11 which says request timeout for which i increased the timeout time in my mvi69mcm module configuration.
Although Prosoft seems to indicate terminating resistors are optional, I find it hard to agree.
Thanks very very much to DIR and Ian S,i wouldn't be able to communicate with my slave devices had you all not helped me.
I have the manual of MVI69MCM which i can give to you all if you require,my email id is [email protected].
I have been to one site where the only way to get the Modbus working was to REMOVE the terminating resistor!
With the resistor fitted, some of the devices would drop out. It was bizarre.
That case wasn't involving an MCM though.
