Modbus and FInning CAT EPMC4.2

[spazzdla]

Has anyone written a program to gather information from a EMCP4.2 controller via modbus?

Anyone skilled with modbus that uses Horner or GE PLC's?  I have the modbus map.

I need to test it without the actual controller I don't want to show up on site and just hope it works.


The main thing I am really looking for is a way to mimic the EMCP4.2 controller with my computer.
