Title: Sample Code Request for DO-More controlling GS4 thru GS-EDVR.
Post by: Saturn_Europa1 on February 15, 2026, 04:14:04 PM

Does anyone have any sample ladder logic code to write to a .RS485SpeedRef and a .RunCommand .  I could not find any samples online. 

I found this in another program at my facility that takes a 0-100 input from a C-More and writes it into a .RS485SpeedRef.  However, I am confused because I thought that the GS drives took unsigned 16 bits instead of Real.  (see attached).

this is a piece of code that manipulates the values you're asking about. it calculates a random speed between 100 and 250Hz, sets the direction, sets the accel and decel rates, then sets the run command:
