How is advanced control represented on a P&ID diagram?

Thread Content

Question: A P&ID shows 40 instrument points, of which 10 are used with 10 other instrument points from another diagram in advanced process control (APC). Should this be indicated on the P&ID? How to express it?

APC seems to be represented in a way similar to PLC… A diamond-shaped box could be considered… If the values are not fed into the DCS, then a hexagonal box should also work
