Hey all,
I'm looking for some advice on setting up a data collection system. The plant I'm working in has about 30 SLC 5/04, on 4 seperate DH+ networks.
Currently we have a CLX Gateway with 2 DHRIO and 1 ENBT card to allow our SCADA system to log data.
The problem with our setup is that the SCADA system logs from each SLC individually (for ex, production data from a press line, from the press slc) and is subject to the data being unavailable due to LOTO procedures.
One idea I have is to put a CLX processor into the gateway and have it poll the SLCs on a regular basis (every 10 minutes or so, depending on the process) and store all the data in a central place. This way if a SLC is powered down for any reason the most recent data (give or take 10 minutes) is available.
Is this a standard practice when dealing with data logging and requiring machinery to be locked out? Is there a downside to this method?
