please help me getting any e-resources
on Ratio control techniques for Blending Process,
Boiler modelling

 

Please, tell me more about your needs. I had some experience on developing automated blend control using Modicon PLC and Intouch software, applying recipes techniques and speed control.

 

I do not remember where I replied in that forum but someone wanted to know about the level control of boiler drum. If that would be your problem, I gave good guidelines. Look under my name in that forum. As you do not describe the part ot the boiler of interest, we end here. Sorry.

Did you get an answer; I have an Allen-Bradley solution if you offer more input. Basically a Linear Equation with slope and offset. Perhaps an adjustable slope.

Provide a Manual/Auto selection and run process in manual, collect data and reuse it in auto mode for a bumbless transfer. Via a series of Copy and Mask Moves you can accomplish this project short time.
