I am new to PLC programming and hope that someone in these forums may be able to assist.
I am mainly using AB PICO controllers and have a need for a simple routine that only perform an output when two inputs occur in a certain order.
I am using two inputs but input 1 must happen before input 2 for the output to occur.
This routine is needed to determine which direction a wheel is rotating i.e. if input 1 closes before input 2 then direction of rotation is forward. If input 2 closes before input 1 then directionof rotation is reversed.
A suggested program routine would be appreciated.
