contact t t with ith the th same number b turns t 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
