Quantum and Modbus

[fer_mayrl]

Hello,

Brian, does serial modbus work with quantum?

I have an indexing table which runs on mach and a cubloc run through serial modbus.

It was working with mach, but we added some weight to the table and i was missing steps, so i changed to quantum to add the S curve acceleration, and it moves and possitions my table ok so far, but i cant connect with the cubloc through modbus.

Was this feature disabled in quantum?
It can open the port but when i read the coils it says that it times outs.

Thanks
Fernando

Just tried the new version of mach3 2.63, and its doing the same thing.

When it was working i was using mach 3 version 2.0.029

Any ideas?

Well,
I reinstalled windows, installed quantum, and regained comunication with the plc.

Wohoooo!
