M9077
Sequence
accumulation
time
measurement
OFF:Time not elapsed
ON: Time elapsed
• Compares the setting value at D9077 with the time
elapsed from the start of measurement
(accumulation time) at every scan. Then, performs
the following operations:
Setting value > Accumulation time:
Turns M9077 ON and clears the accumulation
time.
Setting value < Accumulation time:
Turns M9077 from ON to OFF and clears the
accumulation time. When M9077 is already OFF,
clears the accumulation time.
* When 1 to 255 is designated at D9077, M9077 is
turned ON at the first scan.
* When the value other than 1 to 255 is designated
at D9077, the value in D9077 is reset to 0 and
M9077 is always turned OFF.

M9078
Test mode
request error
flag
OFF:No error
ON: Error
• Turned on when test mode is not available though
a test mode request was made from a peripheral
device. Turned off if test mode becomes available
by making another test mode request.
— Dedicated to A73.
M9079
Servo program
setting error flag OFF:No data error
ON: Data error
• Turned on when the positioning data of the servo
program designated by the instruction has
an error.
Turned off when the data has no error after the
instruction is executed again.
— Dedicated to A73.
M9080
BUSY flag for
execution of
CC-Link
dedicated
instruction
OFF: Number of
remaining
instructions
executable
simultaneously:
1 to 10
ON: Number of
remaining
instructions
executable
simultaneously: 0
Turned ON/OFF according to the number of
remaining instructions (
/ / /
) being executable simultaneously at one
scan.
OFF: Number of remaining instructions
executable simultaneously: 1 to 10
ON: Number of remaining instructions
executable simultaneously: 0
By assigning M9080 as execution condition, the
number of instructions above executed
simultaneously at one scan can be limited to 10 or
less.
