Meaning
• Alternates between ON and OFF according to the
seconds specified at SD414. (Default: n = 30)
• Not turned on or off per scan but turned on and off even
ns during scan if corresponding time has elapsed.
• Starts with off when Programmable Controller power
supply is turned on or CPU module reset is performed.
• Used as dummy contacts of initialization and application
instruction in sequence program.
• SM1038 and SM1037 are turned on and off without regard
to position of key switch on CPU module front. SM1038
and SM1039 are under the same condition as RUN status
except when the key switch is at STOP position, and
turned off and on. Switched off if the key switch is in STOP
1 scan
position. SM1038 is on for one scan only and SM1039 is
off for one scan only if the key switch is not in STOP
position.
1 scan
• When RUN key switch is at PAUSE position or pause
contact has turned on and if SM1040 is on, PAUSE mode
is set and SM1041 is turned on.
• Switched on when the RUN key switch or RUN/STOP
switch is in STOP position.
• Turned on upon completion of sampling trace performed
progress the number of times preset by parameter after STRA
instruction is executed.
completed Reset when STRAR instruction is executed.
• Turning on/off SM1044 can execute STRA/STRAR
ON Same as STRA instruction.
(SM1044 is forcibly turned on/off by a peripheral device.)
instruction
When switched from OFF to ON: STRA instruction
execution
When switched from ON to OFF: STRAR instruction
OFF Same as STRAR
The value stored in SD1044 is used as the condition for
instruction
the sampling trace.
execution
At scanning, at time
• The SM1045 relay is turned on to reset the WDT when the
ZCOM instruction and data communication request batch
processing are executed (used when the scan time
exceeds 200 ms).
• Switched on during sampling trace.
• Sampling trace is not executed unless SM1047 is turned
suspended ON.
Sampling trace is suspended when SM1047 goes OFF.
• When SM1049 is OFF, characters up to NULL (00
are output.
code encountered
• When SM1049 is ON, ASCII codes of 16 characters are
output.
• Switched ON to disable the CHG instruction.
• Switched ON when program transfer is requested.
Automatically switched OFF when transfer is complete.
• When SM1052 is ON, the SEG instruction is executed as
an I/O partial refresh instruction.
When SM1052 is OFF, the SEG instruction is executed as
a 7-SEG display instruction.
