User timing
clock No.0
• This relay repeatedly turns on and off at the
specified scan intervals.
• When the CPU module is powered on or
reset, this relay is set to on from off to start the
clock. Set the intervals of on/off by DUTY
instruction.
•n1: On scan interval
•n2: Off scan interval
When SM1020 to SM1024 are specified for
the DUTY instruction in programs, if the CPU
type is changed from the High Performance
model QCPU or Process CPU to the Universal
model QCPU or LCPU, they are replaced with
SM420 to SM424. (For the Universal model
QCPU and LCPU, SM1020 to SM1024 cannot
be specified.)
