(other than special relays and special registers) in
remote run mode from computer, etc. when M9016
is on. Usable with all
types of CPUs.
M9017
Data memory
clear flag OFF:No processing
ON: Output clear
• Clears the unlatched data memory (other than
special relays and special registers) in remote run
mode from computer, etc. when M9017 is on.
Usable with all
types of CPUs.

M9018
Data link
monitor
switching
OFF:F link
ON: R link • Specifies the lines to be monitored for link
monitoring.
— Dedicated to A3V.
M9020
User timing
clock No. 0
• Relay that repeats on/off at intervals of
predetermined scan.
• When power is turned on or reset is per-formed,
the clock starts with off.
• Set the intervals of on/off by DUTY instruction.
Usable with all
types of CPUs.
M9021
User timing
clock No. 1
M9022
User timing
clock No. 2
M9023
User timing
clock No. 3
M9024
User timing
clock No. 4

M9025
Clock data set
request OFF:No processing
ON: Set requested
• Writes clock data from D9025-D9028 to the clock
element after the END instruction is executed
during the scan in which M9025 has changed from
off to on.
Unusable with An,
A3H, A3M, A3V,
A2C and A0J2H.
M9026 Clock data error
OFF:No error
ON: Error • Switched on by clock data (D9025 to D9028) error
and switched off without an error.
Unusable with An,
A3H, A3M, A3V,
A2C and A0J2H.
M9027
Clock data
display OFF:No processing
ON: Display • Clock data such as month, day, hour, minute and
minute are indicated on the CPU front LED display.
Usable with A3N,
A3A, A3U, A4U,
A73 and A3N
board.
*2
M9028
Clock data read
request OFF:No processing
ON: Read request • Reads clock data to D9025-D9028 in BCD when
M9028 is on.
Unusable with An,
A3H, A3M, A3V,
A2C and A0J2H.
*2
M9029
Data
communication
request batch
process
OFF:No batch process
ON: Batch process
• 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.
• The data communication request 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.)
Usable with AnU
and A2US(H).
