Duplex CPU Systems: Normal Mode only
Note Parallel Processing Mode and Peripheral Servic-
ing Priority Mode cannot be used.
Single CPU Systems: Normal Mode, Parallel Processing
with Asynchronous Memory Access Mode, Parallel Pro-
cessing with Synchronous Memory Access Mode, and
Peripheral Servicing Priority Mode can be used.
1 to 7 steps per instruction
Duplex CPU Systems: Approx. 440 (3-digit function
codes)

0.06 s min.
Duplex CPU Systems: 1.9 ms
Single CPU Systems: 0.5 ms (Normal Mode)
0.4 ms (Parallel Processing Mode)
7 max. (CS1D Expansion Racks)
(C200H Expansion I/O Racks and SYSMAC BUS
Remote I/O Slave Racks cannot be connected.)
288 (cyclic tasks: 32; extra cyclic tasks: 256)
Extra cyclic tasks can be executed each cycle, just like
cyclic tasks, making a total of 288 tasks that can be exe-
cuted each cycle.
Cyclic tasks are executed each cycle and are controlled
with TKON(820) and TKOF(821) instructions.
288 (cyclic tasks: 32; interrupt tasks: 256)
Interrupt tasks can be executed each cycle, just like cyclic
tasks, making a total of 288 tasks that can be executed
each cycle.
Cyclic tasks are executed each cycle and are controlled
with TKON(820) and TKOF(821) instructions.
The following 4 types of interrupt tasks are supported:
Power OFF interrupt task (1 max.), scheduled interrupt
tasks (2 max.), I/O interrupt tasks (32 max.), and external
interrupt tasks (256 max.).
Supported (by global subroutines).
