Hi,
using the PLC is the old school way of thinking. The PLC script runs every few milliseconds and samples the signal each
time it runs. This is called 'polling' an input, it works but is not efficient.
SwiftyJ is right, map the input in the Signal Library, and use a screen load script.
Have a look at the explanation of how the Signal Library works in SignalLibrary.pdf:
