I want to concentrate, log and trend data from our network of AB ControlLogix PLCs. We have a bunch of Citect HMI systems connecting to their specific PLC or PLCs, but they're an old version that cannot connect directly to the CLgx via Ethernet/IP (we connect to the Clx via a DH/RIO card on the ControlLogix). Besides, they're already up their limit in IO points, so using Citect is not an option.
Unfortunately, my budget just barely allows me to get for example a Kepware OPC server with AB ethernet comms, but I would still need the logging/trending and (ideally) web access functionality.
If somebody could give me just a few names of low cost trenders/logger, I will appreciate it very much. Or, if there's something that already includes the comm drivers for AB, much better.
Thanks and best regards,
Bob
