Details
• 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
during scan if corresponding time has elapsed.
• Starts with off when PLC 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
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.
• When RUN key switch is at PAUSE position or pause
contact has turned on and if SM204 is on, PAUSE mode is
set and SM206 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
the number of times preset by parameter after
instruction is executed.
STRAR
Reset when instruction is executed.
• Turning on/off SM803 can execute
instruction.
(SM803 is forcibly turned on/off by a peripheral device.)
When switched from OFF to ON:
Same
When switched from ON to OFF:
The value stored in SD1044 is used as the condition for
the sampling trace.
At scanning, at time Time (10 ms unit)
• The SM1015 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 SM801 is turned
ON.
Sampling trace is suspended when SM801 goes OFF.
• When SM701 is OFF, characters up to NULL (00H) code
are output.
• When SM701 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.
• Switched on when the RUN key switch is in STEP RUN
position.
• Turned on when status latch is completed.
• Turned off by reset instruction.
