Precautions on programming
The uses of the flag in the program
R911C
Control flag
(CH0)
Turns on during execution of pulse output
instructions and then maintains that state
during pulse output from CH0. This flag is
the same for instructions F166 to F175.
Use this to prohibit the simultaneous
execution of other high-speed counter
instructions and pulse output
instructions, and to verify completion
R911D
Control flag
(CH1)
Turns on during execution of pulse output
instructions and then maintains that state
during pulse output from CH0. This flag is
the same for instructions F166 to F175.
Use this to prohibit the simultaneous
execution of other high-speed counter
instructions and pulse output
instructions, and to verify completion
of an action.
R911E
Control flag
(CH2)
Turns on during execution of pulse output
instructions and then maintains that state
during pulse output from CH2. This flag is
the same for instructions F166 to F175.
Use this to prohibit the simultaneous
execution of other high-speed counter
instructions and pulse output
instructions, and to verify completion
R911F
Control flag
(CH3)
Turns on during execution of pulse output
instructions and then maintains that state
during pulse output from CH3. This flag is
the same for instructions F166 to F175.
Use this to prohibit the simultaneous
execution of other high-speed counter
instructions and pulse output
instructions, and to verify completion
of an action.
Note:
• The above flags vary during scanning.
Example: If the above flags are used for more than one time as input conditions, there may be the
different states in the same scan. Replace with internal relays at the beginning of the program as a
measure.
