I am using a Allen-Bradley industrial controller to communicate with the SSC-32. I need to know the ASCII termination character(s) for strings recieved from the SSC-32. Bottom line: I am able to send commands to the servo controller and the servo motor responds appropriately, but I am not receiving any responses when I query the controller. My hunch is that my AB controller is not recognizing term characters for incoming query responses.
Which query commands are you using?
Per the SSC-32 manual, The “Q” command for query movement, returns a single byte which is either a “.” or a “+”; there is no termination character.
The “QP” command for query pulse widtth, returns a single byte, whose (binary) value represents the pulse width for the selected servo with a resolution of 10us; there is again no termination character.
I use the read analog inputs command, VA, and it returns a single byte whose (binary) value represents the voltage on the pin…
