A food processing plant uses a DCS for its continuous mixing process. The plant wants to add a small packaging line that operates independently. Which controller is best suited for the packaging line?

A PLC with its own program and I/O.

Use a remote I/O rack connected to the DCS.

Use a single-loop controller for each packaging machine.

Add the packaging line to the existing DCS.

A pipeline operator requires continuous operation of a critical compressor station. The current PLC has a single power supply and a single network card. The engineer must improve reliability without replacing the PLC. Which combination of changes provides the most effective redundancy for the control system?

Install a second PLC in standby with automatic failover.

Use a redundant fieldbus and a second sensor for each input.

Connect the PLC to a UPS and add a second HMI.

Add a redundant power supply and a second network card with failover.
