What do PV operations, SP operations, and logical operations mean in instruments? I would be extremely grateful if experts could provide some guidance. Thank you!
I heard about PV operations and SP operations for the first time and don’t know what they mean. Logical operations are performed in accordance with Boolean algebra.
Thank you, even though you didn’t provide a satisfactory **.
You mean signal processing in control systems, right?
Yes, that’s exactly the issue I’m talking about. But I don’t know what each of them means; please let me know.
PV operations involve processing signal inputs, such as performing addition, subtraction, multiplication, and division on the PV values of signals, as well as handling alarms. Generally, systems have integrated functional blocks, and you can review the relevant documentation for each one； I’ve never heard of SP operations ； These two terms are generally referred to as analog processing and digital processing. Logical operations are generally used in interlock programs, involving AND and OR relationships.
