Hello
We have approximately 60 remote sites which have Remote Telemetry Units using MicroLogix 1400 PLCs and Viper SC 200 radios. We have a Master Telemetry Unit using a CompactLogix L32E which polls each RTU 1 at a time in order and collects about 8 binary values and 3 analog values.
Our system takes about 5 minutes to poll every site. Fixing the polling times is an ongoing project, however in the mean time we would like to be able to somehow store the flow rate every 30-60 seconds in the RTUs and have the MTU grab all of the stored data and then somehow have our Wonderware Historian save all of the data properly so that we get a nice pretty trend of flow (currently we get what looks like a square wave since the data only changes once every 5 minutes).
Any ideas?
Thanks,
Shawn
