I have been reading the PI Server System Management Guide around the PI Digital States.
I am a little confused as the guide jumps straight into setting them up and configuring them but doesnt cover much around the concepts or purpose of them.
Primarily I am interested in the System digital set. It seems that there are a number of predefined items; or that you can map an interface to define a certain number of items.
I guess I am looking for some clarity around the following:
* What is the purpose of the System digital set?
* Are you supposed to map interfaces to have items within the system digital set or add a new set?
* Is there any way of telling which interfaces are mapped to which items?
* Is there any further documentation which discusses this further?
Any pointers very much appreciated. I feel like I have either misunderstood the intent of the System digital set or how the interfaces are related to it.
