Usage of single-loop PID in Zhejiang University Zhongkong BSCX module?
Thread Content
If I use BSCX blocks for a single-loop PID, should I use SwAM or SwSV for manual/automatic switching? I saw in the notes that SwSV seems to be used. If SwSV is indeed used, then the external setpoint is the output value calculated automatically by the PID block, while the internal setpoint is the value manually entered from the higher-level system, right? If I’m wrong, please point it out; thank you.
Manual/automatic switching is done using SwAM, while internal/external setting is handled by SwSV; that’s what it says in the help information.
If SwAM is a manual/auto switch, then when switched to manual mode, is the upper manual setpoint for the PID block derived from the internal setpoint output?
