A20011 This flag is turned ON for one cycle when program execution
starts (the operating mode is switched from PROGRAM to
RUN/MONITOR).
A20015 When a task switches from INI to RUN status for the first
time, this flag will be turned ON within the task for one cycle
only.
A20014 When a task switches from WAIT or INI to RUN status, this
flag will be turned ON within the task for one cycle only.
The only difference between this flag and A20015 is that this
flag also turns ON when the task switches from WAIT to
RUN status.
A262 to These words contain the maximum cycle time in units of
A263 0.1 ms. 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.) (See note.)
A264 to These words contain the present cycle time in units of
A265 0.1 ms. 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.) (See note.)
A268 When Parallel Processing Mode (with or without synchro-
nous access to I/O memory) is being used, this word con-
tains the peripheral processing cycle time in binary.
0000 to 4E20 hex: 0.0 to 2,000.0 ms (unit: 0.1 ms)
Note: If the cycle time exceeds 2,000.0 ms, then 4E20 hex
will be stored.
Note With a Single CPU System, this would be the same as the instruction execu-
tion cycle if Parallel Processing Mode is being used.
Address
A294 This word contains the task number of the task that was
being executed when program execution was stopped
because of a program error.
A440 This word contains the maximum processing time for any
interrupt task in binary (unit: 0.1 ms).
A441 This word contains the number of the interrupt task that gen-
erated the maximum processing time in binary (8000 to
80FF hex). Bit 15 will turn ON when an interrupt has
occurred. The lower two digits of the hexadecimal value cor-
respond to the task number (00 to FF hex).
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.
