The measurement chain includes the sensor, installation, transmitter, power supply, cable, input terminal, configuration, scaling, validation and process context. A defect in any part can produce a plausible but wrong value. For each instrument record the tag, measured quantity, engineering unit…

]]> PID and Process Control in TwinCAT: From Control Philosophy to Commissioning https://axiotech.co.uk/hyperion-technical-library/article/pid-process-control-twincat/ Sat, 29 Aug 2026 10:24:52 +0000 https://axiotech.co.uk/hyperion-technical-library/article/pid-process-control-twincat/ A PID block is only one component of a control loop. Successful process control depends on the measurement, actuator, process dynamics, execution interval, operating modes, limits and response to faults. Tuning cannot compensate for poor instrumentation, a sticking valve or an undefined mode transition. State the controlled variable, manipulated variable, normal setpoint range…
