Is there a good way to show PLC control logic, both analog and discrete, on a PFD? How would one show manually-inputted PLC parameters (e.g., a manually-inputted flow limit)?
In the past, I've always converted pump discharge head to pressure using the outlet temperature/specific gravity. But with centrifugal compressors, I've used inlet temperature to convert head to pressure. Now I have a case where's there's significant temperature rise across a pump under...
