This PLC is used to control and monitor three bulk power supplies for MCORs. It can also reset MCOR crates. Below are the PLC control and monitor tags.

Note: The ".#" at the end of the tag signifies the bit in the tag used. For example, to reset MCOR 1, you would momentarily set REMOTE_CONTROL[0], bit 3 high. To monitor for a Flow Switch 1 fault, you would monitor bit 1 of STATUS_BITS[0].
