Myself and a Collegue are working on acquiring data from many PLC's and logging the data. Lets just say we want to talk to 20 processors and pull data from each about every minute and a half. Then there is other data we want at 5 sec. intervals, and yet more data pulled at specific times, based on certain inputs or bits.
Now, I know that there is currently software out there to handle this, yet the price is a little steep. So, we have come up with ONE method. A plc5 has it's own "WEB PAGE" and we are coding an application in VB to pull that data and store in a CSV file. If successful, then great. So far, it's looking good, just not sure if I fully want to invest my time on this train of thought. SO, I am finally getting to my question. Is there a way, excluding RSLinx, to communicate with a PLC and explore the data contained within? It would be more efficient to be able to monitor the RAW data instead of constantly reading and refreshing an HTML document. Any thoughts? I'm in GREAT need.

Thank you in advance.
