My scan time is to hign to see an input thats comming on. I am trying to use an Event Task to see it faster. For some reason its saying "the input module is not capable of triggering an event". Im trying to see a valve bank using ethernet. Would I have to configure the module differently? or will it just not work with a valve bank?...Any ideas?? Thanks

Use a LOCAL module, mounted in the chassis.

What controller are you using? What is the part # of the Input Module? Is the module in a local chassis or is it remote? If remote, what network are you using?

Have you set the input filters as short as possible, what are you're RPI settings?

since both platforms use the same software, it's easy for many people to be confused by assuming that the hardware is the same "under the hood" for both platforms ... that is an INcorrect assumption ...
