Table 3.1 Special Relay List (Continued)
Number Name Stored Data Explanation
M9049
Number of output
characters selection
OFF Output until NULL code
ON 16 characters output
! When M9049 is OFF, output continues until the NULL (00H) code.
When M9049 is ON, ASCII code for 16 characters is output.
M9052
(Note-2)
SEG instruction switch
OFF 7-segment display
ON I/O part refresh
!
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.
M9053
(Note-2)
EI/DI instruction switch
OFF Sequence interrupt control
ON Link interrupt control
!
Turn ON when a link refresh enable/disable (EI, DI) instruction is
executed.
M9054 STEP RUN flag
OFF STEP RUN not in effect
ON STEP RUN in effect
! ON when the RUN/STOP key switch is set to the RUN position.
M9055
Status latch completion
flag
OFF Not completed
ON Completed
! Comes ON when status latch is completed.
Goes OFF on execution of a reset instruction.
M9056
Main side P/I setting
request
ON During P/I set request
OFF Other than during P/I set request
M9057
Sub side P/I setting
request
ON During P/I set request
OFF Other than during P/I set request
!
Turns ON the P/I set request at completion of transfer of the other
program (e.g. subprogram when the main program is during run)
during run. Automatically turned OFF at completion of P/I setting.
M9058
Main side P/I setting
completion
Turns ON instantaneously at
completion of P/I setting.
M9059
Sub side P/I setting
completion
Turns ON instantaneously at
completion of P/I setting.
!
Turns ON instantaneously at completion of P/I setting and turns OFF
immediately.
M9065
Split processing
execution detection
OFF Not during split processing
ON During split processing
! ON during execution of the instruction for AD57(S1) or AD58 in split
processing and turns OFF at completion of execution (split
processing is not performed).
M9066
(Note-2)
Split processing request
flag
OFF Batch processing
ON Split processing
! M9066 is turned ON to split-process the instruction which is designed
for AD57(S1) or AD58 and has long processing time since that
instruction increases the scan time substantially.
M9070
(Note-2)
A8UPU/A8PUJ search
time
OFF Without read time reduction
ON Read time reduction
! Turned ON to reduce the time required for the A8UPU/A8PUJ to
search. (In this case, the scan time of the CPU increases 10%.)
M9081
Communication request
registration area busy
signal
OFF Communication request
registration areas free
ON No communication request
registration areas free
! Turns ON when there are no free registration areas among the 32
areas used for registering the standby instructions (FROM/TO) to be
given to the MNET/MINI(-S3).
M9084
(Note-2)
Error check
OFF Error check executed
ON No error check
! Set whether or not the error check shown below is executed on END
instruction processing. (Used to shorten END instruction processing
time.)
(1) Blown fuse check
(2) I/O module verification check
(3) Battery check
M9091
(Note-1)
Instruction error flag
OFF No error
ON Error occurrence
! Turns ON at occurrence of an instruction-related error.
Remains ON if the condition returns to normal.
M9094
(Note-2)
(Note-3)
I/O change flag
OFF Not changed
ON Changed
! After setting the first I/O number of the changed I/O module to
D9094, turning M9094 ON enables the I/O module to be changed
online. (Only one module may be changed in single setting.)
! When making an I/O change during RUN, use the program or the
test mode of the peripheral device. During STOP, use the test mode
of the peripheral device.
! Do not change the RUN/STOP mode to the other until I/O change is
finished.
M9100
Presence/absence of
SFC program
OFF SFC program absent
ON SFC program present
! Turns ON when the SFC work area is secured for the SFC program
registered.
! OFF when there is no SFC program registered or the SFC work area
is not secured.
M9101
(Note-2)
Start/stop of SFC
program
OFF SFC program stop
ON SFC program start
!
Turned ON by the user to start the SFC program.
Turn OFF to turn OFF the operation output of the execution step and
stop the SFC program.
M9102
(Note-2)
Starting status of SFC
program
OFF Initial start
ON Continuous start
!
Choose the start step when the SFC program is restarted by M9101.
ON : The execution conditions at an SFC program stop are all
cleared and the program is started at the initial step of block 0.
OFF : The SFC program is started at the execution block and
execution step it had been stopped.
!
Once turned ON, M9102 is latched (compensated for power failure)
by the system.
M9103
(Note-2)
Presence/absence of
consecutive transition
OFF Without consecutive transition
ON With consecutive transition
!
Select whether or not to execute all the steps whose transition
conditions have held within one scan when the transition conditions
of consecutive steps have all held.
ON : Executed consecutively. (With consecutive transition)
OFF : One step is executed at each scan.
(Without consecutive transition)
M9104
Consecutive transition
inhibit flag
OFF Transition finished
ON Transition not executed
!
Turns ON when consecutive transition is not executed during
consecutive transition, and turns OFF when the transition of one step
is finished. Describing M9104 under the AND condition as a
transition condition inhibits the consecutive transition of the
corresponding step.
