Which activity is not typically included in commissioning efforts?

• A. Operation of field devices
• B. Test for damaged equipment
• C. Test of logic functionality
• D. I/O to logic solver are all fully operational

Answer: (C)

In commissioning efforts, the primary focus is on ensuring that all components of a system are correctly installed, configured, and functioning as intended. While testing logic functionality is indeed an important aspect of system validation, it is generally not considered part of the commissioning phase. Commissioning primarily involves verifying that physical components, such as field devices and connections to the logic solver, are operational and that there are no physical defects or issues.

The activities typically included in commissioning would cover the operation of field devices to confirm that they respond correctly to commands, testing for any damaged equipment that may compromise system integrity, and verifying that inputs and outputs (I/O) to the logic solver are fully operational. These activities focus on the hardware aspect of the systems rather than the internal logic functionalities which may be tested later during the validation or maintenance phases. Therefore, testing of the logic functionality is usually treated as a separate activity, distinguishing it from the core objectives of commissioning.
