Present Value of
High-speed
Counter
These words contain the present value of the high-speed
counter.
Read
• Cleared when power is turned ON.
• Cleared when operation starts.
• Updated each cycle during over-
see process.
• Updated when present value is
read using PRV instruction.
Present Value of
Internal Pulse
Output, Absolute
Value for Abso-
lute Coordinates
These words contain the absolute value of the actual
movement in relation to the internal pulse origin when
pulses are being output to the error counter.
Data range: 8000 0000 to 7FFF FFFF hex
(

First Cycle Flag
A200.11
ON for one cycle after PLC operation begins (after the
mode is switched from PROGRAM to RUN or MONITOR,
for example).
Read-only
Initial Task Execution Flag
A200.15
ON when a task is executed for the first time, i.e., when it
changes from INI to RUN status.
Read-only
Task Started Flag
A200.14
When a task switches from WAIT or INI to RUN status,
this flag will be turned ON within the task for one cycle
only.
Note
The only difference between this flag and
A200.15 is that this flag also turns ON when the
task switches from WAIT to RUN status.
Read-only
Maximum Cycle Time
A262 to
A263
These words contain the maximum cycle time since the
start of PLC operation. The cycle time is recorded in 8-
digit hexadecimal with the leftmost 4 digits in A263 and
the rightmost 4 digits in A262.
0 to FFFFFFFF: 0 to 429,496,729.5 ms (0.1-ms units)
Read-only
Present Cycle Time
A264 to
A265
These words contain the present cycle time in 8-digit
hexadecimal with the leftmost 4 digits in A265 and the
rightmost 4 digits in A264.
Read-only
10-ms Incrementing Free
Running Timer
A0
This word contains the system timer used after the power
is turned ON.
A value of 0000 hex is set when the power is turned ON
and this value is automatically incremented by 1 every 10
ms. The value returns to 0000 hex after reaching FFFF
hex (655,350 ms), and then continues to be automati-
cally incremented by 1 every 10 ms.
Note:
The timer will continue to be incremented when
the operating mode is switched to RUN mode.
Example: The interval can be counted between
processing A and processing B without requiring timer
instructions. This is achieved by calculating the
difference between the value in A0 for processing A and
the value in A0 for processing B. The interval is counted
in 10 ms units.
Read-only
100-ms Incrementing Free
Running Timer
A1
This word contains the system timer used after the power
is turned ON.
A value of 0000 hex is set when the power is turned ON
and this value is automatically incremented by 1 every
100 ms. The value returns to 0000 hex after reaching
FFFF hex (6,553,500 ms), and then continues to be
automatically incremented by 1 every 100 ms.
Note:
The timer will continue to be incremented when
the operating mode is switched to RUN mode.
Example: The interval can be counted between
processing A and processing B without requiring timer
instructions. This is achieved by calculating the
difference between the value in A0 for processing A and
the value in A0 for processing B. The interval is counted
in 100 ms units.
