Section 2-6
Note
A Programming Console cannot be connected to a CP1H CPU Unit. If
Use
programming console
is set, the CPU Unit will start in RUN mode.
2-6
Power OFF Operation
2-6-1
Overview
The following processing is performed when CPU Unit power is turned OFF.
Power OFF processing will be performed if the power supply voltage falls
below the specified value while the CPU Unit is in RUN or MONITOR mode.
1,2,3...
1.
The CPU Unit will stop.
2.
Outputs from all Output Units will be turned OFF.
Note
(1) All outputs will turn OFF despite the status of the I/O Memory Hold Bit or
I/O Memory Hold Bit at power ON settings in the PLC Setup.
(2) AC Power
85% of the rated voltage: 85 V or less for a 100 to 240 V AC system
(3) DC Power
90% of rated voltage: 20.4 V DC or less
The following processing will be performed if power drops only momentarily
(momentary power interruption).
1,2,3...
1.
The system will continue to run unconditionally if the momentary power in-
terruption lasts less than 10 ms for AC power or 2 ms for DC power, i.e.,
the time it takes the rated voltage at 85% or less to return to 85% or higher
is less than 10 ms for AC power or the time it takes the rated voltage at 90%
or less to return to 90% or higher is less than 2 ms for DC power.
