CP-406 PLC Monitor 2
PLC Monitor 2 (CP-406) determines which PLC bit will be monitored in PLC Mon 2 Val (MP-109). The PLC Mon 2 Val
(MP-109) displays the name of the bit rather than “PLC Mon 2 Val”. To select a PLC bit to monitor, enter the number of
the bit or by use the Scroll keys (^ or v) to scroll through the list. This bit can be monitored in any screen when the
code select line set to PLC Mon 2 Val (MP-109).
Minimum Value: 0 Maximum Value: 223
Default Value: 13 Units: PLC Bits
CP-407 PLC Bit Set
PLC Bit Set (CP-407) forces a PLC bit to be set to “1”. Enter the number of the bit that you want to set to “1”. PLC Bit
Set (CP-407) tests your PLC program rather than commanding a direct operation. The bit is set prior to the PLC program
execution but after all the inputs, comparisons, timers and counters have had their status bits set up. However, the PLC
could clear this bit and unpredictable results can occur. Do not attempt to set a PLC bit that is controlled by an OUT
instruction in the PLC program. If you need to force an output, use Diag DO in the diagnostics screen.
Minimum Value: 0 Maximum Value: 223
Default Value: 3 Units: PLC Bits
CP-408 PLC Bit Clear
PLC Bit Clear (CP-408) forces a PLC bit to be reset to “0”. Enter the number of the bit that you want to clear. PLC Bit
Clear (CP-408) tests your PLC program rather than commanding a direct operation. The bit is cleared prior to the PLC
program execution but after all the inputs, comparisons, timers and counters have set up their status bits. However, the
PLC could set this bit and unpredictable results can occur. Do not attempt to clear a PLC bit that is controlled by an
OUT instruction in the PLC program. If you need to force an output, use Diag DO in the DIG I/O Test diagnostics
screen.
Minimum Value: 0 Maximum Value: 223
Default Value: 2 Units: PLC Bits
CP-410 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
the Tmr1 Out bit (24) in the PLC is activated = 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”.
Minimum Value: 0 Maximum Value: 86400
Default Value: 1.000 Units: Seconds
CP-411 Tmr1 on Tm
Timer 1 on Time (CP-411) is the time, in seconds, from which Tmr 1 Out is activated (= 1) until Tmr1 Out is deactivated
(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 1 on-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).
Minimum Value: -1 Maximum Value: 86400
Default Value: -1 Units: Seconds
