Can someone please shed some light on my problem
Getting modbus working with a hitachi x200 ?
I have read for days on this and i believe i have it set up correctly
But i get timeout errors once i open the port and try to read data
I have a rs232 to rj485 on a pci serial port card
I get no errors in mach opening and closing the port so this much
I think is right
I have the baud rate and settimgs setup on the pc to match mach
I have the swith on the vfd to rj485
Seems to be from the converter to the vfd where my probl lies
Just not sure where to lool now
