Hello, I am working with a micrologix 1100 allen bradley plc and I need to send and receive ascii code to a sensor device. The syntax for the commands that the manufacture states are the following:
set:LO=xxxx -(to set the low speed)
set:HI=xxxx -(to set the high speed)
I can get this to work using an AWA write command with a ACN command by typing the (set:LO=) in my ST string file and loading the xxxx variable from an hmi into and interger file and using an AIC command.
it works pretty well.
What I am having problems with is how to read information from the sensor.
get:LO=xxxx
get:HI=xxxx...
I am not certain how I can read these with and ARL or ARD instruction.. Or do i need to do something else. I will also need to convert it back to an integer file.
Thank you for your time!!!
