!
Writes the clock data stored in D9025 to D9028 to the clock devices
after execution of the END instruction in the scan in which M9025 is
switched ON.
! Comes ON when there is an error in he clock data (D9025 to D9028)
values. OFF when there is no error.
!
When M2098 is ON, the clock data is read to D9025 to D9028 as
BCD data.
! These relays generate the 0.1 second, 0.2 second, 1 second, 2
second, and 1 minute clocks.
! These relays do not go ON/OFF with each scan but when their
respective fixed intervals have elapsed, even during a scan.
!
These relays start from the OFF status when the power is turned on
or resetting.
!
Relay used for initialization during a sequence program or as a
dummy contact for an application instruction.
! M9036 and M9037 retain their ON or OFF status regardless of the
settings of the key switch on the front of the CPU, but M9038 and
M9039 change in accordance with the key switch status. They go
OFF when the key switch is set to the STOP position.
1 scan
When the key switch is at a position other than STOP, M9038 comes
ON for one scan only, and M9039 goes OFF for one scan only.
1 scan
!
When the RUN/STOP key switch is set to PAUSE or the remote
PAUSE contact is turned on, provided M9040 is ON, the PAUSE
status is established and M9041 comes ON.
! ON when the RUN/STOP key switch is set to STOP.
!
Comes ON on completion of the number of sampling traces set in the
parameters are completed after execution of the STRA instruction.
After that, it is reset by execution of the STRAR instruction.
! ON during execution of a sampling trace
! A sampling trace cannot be executed unless M9047 has been turned
ON.
When M9047 is turned OFF, the sampling trace is stopped.
! When M9049 is OFF, output continues until the NULL (00H) code.
When M9049 is ON, ASCII code for 16 characters is output.
! When M9052 is ON it is executed as the I/O partial refresh
instruction. When M9052 is ON, it is executed as the 7-segment display
instruction.
! Turn ON when a link refresh enable/disable (EI, DI) instruction is
executed.
