Meaning
• Turned on when operation error occurs during execution
of application instruction.
: Error • Remains ON if the condition is restored to normal
thereafter.
• Carry flag used in application instruction.
: Carry ON
• Clears the data memory including the latch range (other
than special relays and special registers) in remote run
: Output claered
mode from computer, etc. when SM1016 is on.
• Clears the unlatched data memory (other than special
relays and special egisters) in remote run mode from
: Output claered
computer, etc. when SM1017 is on.
• Relay which repeats on/off at intervals of predetermined
scan.
• When power is turned on or reset is per-formed, the clock
starts with off.
n2 scan
Set the intervals of on/off by DUTY instruction.
n1 scan
n1: ON scan interval
n2: OFF scan interval
• Writes the clock data stored in SD1025 to SD1028 to the
: Set request present CPU module after the END instruction is executed in the
used scan in which SM1025 turned from OFF to ON.
• Switched on by clock data (SD1025 to SD1028) error
: Error
• Clock data is read from SD1025 to SD1028 and month,
day, hour, minute and minute are indicated on the CPU
: Display
module front LED display.
• Reads clock data to SD1025 to SD1028 in BCD when
: Read request SD1028 is on.
• The SM1029 relay is turned on using a sequence program
to process all data communication requests accepted
during one scan in the END processing of that scan.
conducted • The batch processing of the data communication requests
: Batch processing can be turned on and off during running.
conducted • The default is OFF (processed one at a time for each END
processing in the order in which data communication
requests are accepted).
0.05s
• 0.1 second, 0.2 second, 1 second and 2 second, clocks
are generated.
0.1s
• 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
0.5s
CPU module reset is performed.
1s
• 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 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
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.
