Description
• Clears the data memory including the latch range
OFF: No processing (other than special relays and special registers) in
ON: Output clear remote run mode from computer, etc. when M9016
is on.
• Clears the unlatched data memory (other than
OFF:No processing
special relays and special registers) in remote run
ON: Output clear
mode from computer, etc. when M9017 is on.
OFF:F link • Specifies the lines to be monitored for link
ON: R link monitoring.
• Relay that repeats on/off at intervals of
predetermined scan.
• When power is turned on or reset is per-formed,

• Set the intervals of on/off by DUTY instruction.
n1
scan
• Writes clock data from D9025-D9028 to the clock
OFF:No processing element after the END instruction is executed
ON: Set requested during the scan in which M9025 has changed from
off to on.
OFF:No error • Switched on by clock data (D9025 to D9028) error
ON: Error and switched off without an error.
OFF:No processing • Clock data such as month, day, hour, minute and
ON: Display minute are indicated on the CPU front LED display.
OFF:No processing • Reads clock data to D9025-D9028 in BCD when
ON: Read request M9028 is on.
• Turn M9029 on in the sequence program to
process all data communication requests, which
have been received in the entire scan, during END
process of the scan.
OFF:No batch process
• The data communication request batch process
ON: Batch process
can be turned on or off during operation.
• Off in default state (Each data communication
request is processed at the END process in the
order of reception.)
