Symbolic Names For I/Os - ABB AC500 Introduction Manual

Symbolic names for I/Os

In our example we use one digital input and one digital output. We want to label them with symbolic
names. Proceed as follows: Click on the
configuration:
Now define a symbolic name for the digital input (digital input 0) as follows. First click on the
front of "Digital Inputs 0-15[FIX]":
In the line of input 0, click twice on "AT". Then enter the symbolic name, e.g. I0dig.
Complete your input by pressing the <Enter> key (displayed entry: I0dig AT %IX0.0 ...). Now the
program can access this input by its symbolic name. Using the same procedure, we then have to label
the digital output with a symbolic name. Click on the
outputs 16-31 [FIX]".
