I'm new to PLC and right now i've to modify an old SCADA system build by FIX32 (ver6.15).
I've an AI tag that monitor the flowrate of a discharger. What I've to do is to log the volume that passes throught this discharger in 24 hr (from 8pm to 7:59pm). In the case the volume flow excess a preset value, an alarm will be sounded to alert operators. In the mean time, this daily log record can be opened up for reference, where data older than 1 years will be deleted automatically.
I'm confused with the group tags as well. In what situation am I supposed to use it?
Thanks in advance!
