Tips

Start from the flow measurement, that's the easiest one. You can done it the same way as you did the measurement in the previous assignment. But check the type of the Profibus card from the I/O list.

HS-valves

Check the principle from picture 1.

Remove the open and close limits from mgv's parameters (inside the function block).

Control valves

Use the pid function block.

Check from the typehelp to do the interclock.

Pump

Use the ins member for the feedback from the frequency converter.

Profibus IO functions

Check basics from the manual
