After SEL
OGIC
Control Equations settings changes have been made and the settings are saved,
the SEL-351P responds with the following message:
xxx Elements remain available
indicating that “xxx” Relay Word bits can still be used for the particular setting group.

The relay elements and logic (and corresponding SEL
OGIC
Control Equation settings and
resultant Relay Word bits) are processed in the order shown in Table APPENDIX G: .2 (top to
bottom). They are processed every quarter-cycle (1/4-cycle), and the Relay Word bit states
(logical 1 or logical 0) are updated with each quarter-cycle pass. Thus, the relay processing
interval is 1/4-cycle. Once a Relay Word bit is asserted, it retains the state (logical 1 or logical 0)
until it is updated again in the next processing interval.
