Want to fetch data from AC500 controllers
I have two requirements
1. There are total 15-20 CHMI 6 & Automation Builder 1.2 system computers with dedicated controllers PM5xx-eth, and I have to fetch selected data from their controllers, just to display on my centralized CHMI 6 computer "Similar System" without doing any modification in existing system. However all computers are on the same network and dedicated IP address.
How i can do this thing?
2. How to fetch OPC data from each computer, as they are also fetching the data from different make of PLC through Kepserver 6 (as this data will not be available in PLC program).
Thanks in advance.
1.If possible, tunnel the data on PLC level, I don't know what protocols an AC500 have built-in. Depending on cost, a custom UDP/TCP application can be created in AC 800M acting as a concentrator to receive data from virtually any device capable of sending custom UDP/TCP telegrams. Once in AC 800M, use MMS to transfer the data to CHMI.
2. OPC can be tunneled via DCOM or a proprietary tunneler software (at some cost, though...). But having 20 OPC DA connectors receiving OPC tunneled data might be too much for your concentrator system.
Seek to implement data transfer on PLC level and use as little as possible of system-to-system transfer via OPC. Perhaps you can use a common protocol, e.g. MODBUS to make PLC transfer with less programming effort?
