Retrieving all Data


Recommended Posts

I am wondering if it is possible to load all of the current values for all analog and digital inputs from a PLC. I have successfully connected to a PLC using:

PLC plc = PLCFactory.GetPLC(ethernet, 0);

Is there an easy way to use this PLC object to retrieve all values, or do I need to specifically know information (Address, etc) of each value I would like to read. If I do need to read them individually, how do I determine these parameters?

Thanks in advance
