SEL-351 Instruction Manual
RELAY WORD BITS (USED IN SELOGIC CONTROL EQUATIONS)
Relay Word bits are used in SELOGIC Control Equation settings. Numerous SELOGIC Control
Equation settings examples are given in Section 3 through Section 8. SELOGIC Control Equation
settings can also be set directly to 1 (logical 1) or 0 (logical 0). Appendix G: Setting SELOGIC
Control Equations gives SELOGIC Control Equation details, examples, and limitations.
The Relay Word bit row numbers correspond to the row numbers used in the TAR command [see
TAR Command (Target) in Section 10: Serial Port Communications and Commands]. Rows 0
and 1 are reserved for the display of the two front-panel target LED rows.
