(Y) 8,192 points (Y0 to Y511F) Externally outputs on or off state.
(R) 14.192 points (R0 to R886F) Relay which turns on or off only within program.
(L) 10,240 points (L0 to L639F) This relay is a shared relay used for
MEWNET link system.

(T0 ( to T2999/ C3000 to C3071) ) tact with the same number turns on.
Counter (C) ( ) If a CT instruction has counted up, the con- con
(* Notes 1 and 2)
tact with the same number turns on
Pulse relay (P) 2,048 points (P0 to P127F) This relay is used to turn on only for one
scan duration programmed with the OT"
and OT# instructions.
Error alarm relay (E) 2,048 points (E0 to E2047) If turned on while the unit is running, this
relay stores the history in a dedicated buffer.
Program this relay so that it is turned on at
the time of abnormality.
Special
(R) 176 points (R9000 to R910F) Relay which turns on or off based on spe-
internal relay
cific conditions and is used as a flag.
