The post AutoQuiz: Changing the Point of Origin for Input Data and Output Signal Destination with a DCS first appeared on the ISA Interchange blog site.
Today’s automation industry quiz question comes from the ISA Certified Control Systems Technician (CCST) program. Certified Control System Technicians calibrate, document, troubleshoot, and repair/replace instrumentation for systems that measure and control level, temperature, pressure, flow, and other process variables. Click this link for information about the CCST program. This question comes from the Level I study guide, Domain 2, Loop checking. Level I represents a professional who has a five-year total of education, training, and/or experience.
Changing the point of origin for input data and the output signal destination is easy with a distributed control system (DCS) because many changes can be implemented by:
a) relocating wire jumpers in a junction box
b) changing the pneumatic tubing connections
c) reassigning inputs/outputs by changing loop configuration
d) installing new transmitters and final control elements
e) none of the above
