100-ms Incrementing Free
Running Timer
(Unit versions 3.0 or later)
A001 This word contains the system timer used after the power is
turned ON.
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.

1-s Incrementing Free
Running Timer
(Unit version 4.0 or later)
A002 This word contains the system timer used after the power is
turned ON.
0000 hex is set when the power is turned ON and this value
is automatically incremented by 1 every 1 s. The value
returns to 0000 hex after reaching FFFF hex (65,535 s), and
then continues to be automatically incremented by 1 every
1 s.
Note: The timer will continue to be incremented when the
operating mode is switched to RUN mode.

Maximum Cycle Time A262 to
A263
These words contain the maximum cycle time in units of
0.1 ms. In a Parallel Processing Mode, the maximum cycle
time of the program execution cycle will be given.
The time is updated every cycle and is recorded in 32-bit
binary (0 to FFFF FFFF, or 0 to 429,496,729.5 ms). (A263 is
the leftmost word.)
Read-only
Present Cycle Time A264 to
A265
These words contain the present cycle time in units of
0.1 ms. In a Parallel Processing Mode, the maximum cycle
time of the program execution cycle will be given. The time is
updated every cycle and is recorded in 32-bit binary (0 to
FFFF FFFF, or 0 to 429,496,729.5 ms). (A265 is the leftmost
word.)
Read-only
Peripheral Servicing Cycle
Time
(CJ1-H CPU Units only)
A268 In Parallel Processing with Synchronous or Asynchronous
Memory Access, this word contains the peripheral servicing
cycle time in units of 0.1 ms. The time is updated every cycle
and is recorded in 16-bit binary (0 to 4E20 hex, or 0.0 to
2,000.0 ms).

Task Number when Program
Stopped
A294 This word contains the task number of the task that was
being executed when program execution was stopped
because of a program error.
Read-only
Maximum Interrupt Task
Processing Time
A440 Contains the Maximum Interrupt Task Processing Time in
units of 0.1 ms.
Read-only
Interrupt Task with Max.
Processing Time
A441 Contains the task number of the interrupt task with the maxi-
mum processing time. Hexadecimal values 8000 to 80FF
correspond to task numbers 00 to FF. Bit 15 is turned ON
when an interrupt has occurred.
Read-only
IR/DR Operation between
Tasks
(Not supported by CJ1@-
CPU@@ CPU Units.)
A09914 Turn ON this bit to share index and data registers between
all tasks. Turn OFF this bit to use separate index and data
registers between in each task.
