I want to create a trend which will show an expected value of a sensor (e.g. temperature) of all the process time (e.g. 10 hours). While I'm in these 10 hours (While the process is still running) I want to see the progress of the real-value of the sensor.

I whish to see the real-value in real-time following the expected-value.

I have no clue how doing it. It seems to be a little bit complicated because future values or supposed to be showed (by the excpected-value)

How can I do it using Cimplicity, using itself or 3rd party applications?

Grate thanks

 

You can add a 3rd party application to your SCADA programme.

TrendWorX32 by ICONICS connects to OPC Data Access tags and stores the values in an open database (Access, MSDE, SQL Server). TrendWorX32 itself acts as an OPC HDA (historical data access) Server in respect to other trend analyses software.

A collected trend period can be defined as an "ideal trend". A realtime trend can be plotted against the ideal trend.

If your SCADA software is up to date with the OPC standards, you can have it directly connect to the OPC H.D.A tags in TrendWorX32. Otherwise you can add the TrendWorX32 Viewer ActiveX Control to your SCADA displays.
