Instruction Execution Times and Number of Steps
Note Scheduled interrupt tasks can be executed (while an instruction is being exe-
The interrupt response time of scheduled interrupt tasks is the time taken
from after the scheduled time specified by the MSKS(690) instruction has
elapsed until the interrupt task has actually been executed.
The length of the interrupt response time for scheduled interrupt tasks is 1 ms
max.
cuted, or by stopping the execution of an instruction) during execution of the
user program, I/O refresh, peripheral servicing, or overseeing. The interrupt
response time is not affected by the scheduled time elapsing during any of the
above processing operations.
Some scheduled interrupts, however, are not executed during other interrupt
tasks even if the scheduled interrupt conditions are satisfied. Instead, the
scheduled interrupts are executed in order of priority after the other interrupt
task has completed execution and the software interrupt response time (1 ms
max.) has elapsed.
The interrupt response time for external interrupt tasks differs depending on
the Unit or Board (Special I/O Unit, CS-series CPU Bus Unit, or Inner Board)
that is requesting the external interrupt task of the CPU Unit and the type of
service requested by the interrupt. For details, refer to the appropriate opera-
tion manual for the Unit or Board being used.
Power OFF interrupt tasks are executed within 0.1 ms of the power being con-
firmed as OFF.
The following table lists the execution times for all instructions that are avail-
able for CS1D CPU Units.
The total execution time of instructions within one whole user program (i.e.,
within all the tasks that are executed in a cycle) is the process time for pro-
gram execution when calculating the cycle time (See note.).
The conditions (e.g., operands) under which an instruction is executed affect
the execution time, as does the model of the CPU Unit. The execution time
can also vary when the execution condition is OFF.
