PLC TIMERS P1/1
Tmr1 Delay
Timer 1 Delay (CP-410) is the time, in seconds, from which Timer 1 becomes enabled (Tmr1 En bit going from “0” to “1”)
until Tmr1 Out bit (24) in the PLC is going active (1). When the Tmr1 En bit (124) returns to “0”, the Tmr1 Out bit (24)
is reset to “0” and the delay-time is reset to “0”.
Tmr1 on Tm
Timer 1 on Time (CP-411) is the time, in seconds, from which Timer 1 is going active (= 1) until Tmr1 Out is going
inactive (back to “0”). When the Tmr1 En bit (124) returns to “0”, the Tmr1 Out bit (24) is reset = “0” and the on-
time is reset to “0”. If you want Timer 1on-time to be infinite (“On” until Tmr1 is disabled with Tmr1 En = “0”),
then enter a value of "-1" into Tmr1 on Tm (CP-411).
Tmr2 Delay
Timer 2 Delay (CP-412) is the time in seconds from which Timer 2 becoming enabled (Tmr2 En bit going from “0” to “1”)
until Tmr2 Out bit (25) in the PLC going active (1). When the Tmr2 En bit (125) returns to “0”, the Tmr2 Out bit (25) is
reset to “0” and the delay-time is reset to “0”.
Tmr2 on Tm
Timer 2 on Time (CP-413) is the time, in seconds, from which Timer 2 is going active (= 1) until Tmr2 Out is going
inactive (back to “0”). When the Tmr2 En bit (125) returns to “0”, the Tmr2 Out bit (25) is reset = “0” and the on-
time is reset to “0”. If you want Tmr2 on-time to be infinite (“On” until Tmr2 is disabled with Tmr2 En = “0”), then
enter a value of "-1" into Tmr2 on Tm (CP-413).
Tmr3 Delay
Timer 3 Delay (CP-414) is the time, in seconds, from which Timer 3 becomes enabled (Tmr3 En bit going from “0” to “1”)
until Tmr3 Out bit (26) in the PLC is going active (1). When the Tmr3 En bit (126) returns to “0”, the Tmr3 Out bit (26)
is reset to “0” and the delay-time is reset to “0”.
Tmr3 on Tm
Timer 3 on Time (CP-415) is the time, in seconds, from which Timer 3 is going active (= 1) until Tmr3 Out is going
inactive (back to “0”). When the Tmr3 En bit (126) returns to “0”, the Tmr3 Out bit (26) is reset = “0” and the on-
time is reset to “0”. If you want Timer 3 on-time to be infinite (“On” until Tmr3 is disabled with Tmr3 En = “0”),
then enter a value of "-1" into Timer 3 on Time (CP-415).
Tmr4 Delay
Timer 4 Delay (CP-416) is the time, in seconds, from Timer 4 becoming enabled (Tmr4 En bit going from “0” to “1”)
toTmr4 Out bit (27) in the PLC going active (1). If Tmr4 becomes disabled, the delay-time is retained so the timing can
continue when Tmr4 is re-enabled. The Tmr4Rst bit (128) in the PLC must be used to reset the delay time to “0”.
Tmr4 on Tm
Timer 4 on Tm (CP-417) is the time, in seconds, from Tmr4 Out going active (= 1) until Tmr4 Out going inactive (back
to “0”). When Tmr4 becomes disabled, the on-time is retained so the timing can continue when Tmr4 is re-enabled.
The Tmr4 Rst bit (128) in the PLC must be used to reset the on-time to “0”. If you want Tmr4 on-time to be infinite (“On”
until Tmr4 is reset with Tmr4 Rst = 1) then enter a value of “-1” in Tmr4 on Tm (CP-417).
Tmr4 Time
Timer 4 Time (MP-107) displays the elapsed time, in seconds, for Timer 4 during the delay part of it's operation.
