Hi all,
Having some issues setting up a PIDE Cascade control loop.
Have been trying to go through the Wp008 doc but there's probably something easy/small that I'm missing.
I have a tank with an oil jacket which is directly heated up using resistive heaters (SSR). The oil jacket in turn heat transfers to the tank product (wax).
The application is heat only, as the client generally turns on the oil jacket heaters and leaves overnight for the wax to melt.
Am I correct in assuming that this calls for a PIDE Cascade Loop?
Primary Loop - Wax Temperature - 4-20mA - 0-200C with SP cutoff at 150.
Secondary Loop - Oil Jacket Temperature - as above.
Secondary Loop output goes to SRTP for the SSR output.
Thanks ahead for any help.
