Hi all,
I am setting up a small SCADA system using Micrologix 1100 PLCs - about 8 of them. I just want to log data into a data historian like Canary Labs so that I can tie process variables with batch numbers and run some trend charts. I was thinking of using KepWare for the OPC interface between the Historian and the 1100.
Do I need to use the data logging function to queue up the data or can I simply update the tags when a process is complete? I guess it's the retrieving of OPC data that confuses me. A little help or kick in the right direction would be greatly appreciated.
