Description of Tasks

Section 1-6

Task Execution Time

While a task is on standby, instructions in that task are not executed, so their
OFF instruction execution time will not be added to the cycle time.

Note From this standpoint, instructions in a task that is on standby are just like

instructions in a jumped program section (JMP-JME).

Since instructions in a non-executed task do not add to the cycle time, the
overall system performance can be improved significantly by splitting the sys-
tem into an overall control task and individual tasks that are executed only
when necessary.

Earlier system

Most instructions 
are executed.
(Instructions in 
subroutines and 
jumps are 
executed only 
when neces
sary.)

CS/CJ-series PLCs

Instructions are 
executed only 
when necessary.

Task 0

Task 1

Task 2

Task 3
