How can I convert a PID into a DCS logic diagram? Thank you all!
First, understand the drawings clearly, then figure out the logic, and then write it yourself
As mentioned on the second floor, it is necessary to understand the PID drawings on one’s own before proceeding with DCS configuration. Typically, design institutes will provide explanations for the control circuits as well as interlock logic diagrams. This is especially true for complex control circuits and interlock logic diagrams; it’s difficult to work without such explanations, so it’s necessary to communicate well with the designers.
It can’t. PID cannot fully describe the interlocking relationships between devices (such as simultaneous shutdown, simultaneous startup, mutual backup, etc.), nor does it provide complete information about the devices themselves (such as the rapid opening of valves, etc.). It also lacks detailed information regarding control signals and feedback signals. To be precise, the PID diagram is not the direct upstream data of the logic diagram. The upstream data for a logic diagram are control instructions, in various forms such as SAMA diagrams or textual descriptions.
For a standalone device, ask the manufacturer for the logic diagram~~
Generally speaking, it ultimately boils down to communicating with the technical department again
