Status Transitions

INI (Disabled) status
A task attribute can be set to control when the task will go to READY status.
The attribute can be set to either activate the task using the TASK ON instruc-
tion or when RUN operation is started.
A TASK ON (TKON(820)) instruction is used to switch an instruction-activated
cyclic task from Disabled status or Standby status to READY status.
An operation-activated cyclic task will switch from Disabled status to READY
status when the operating mode is changed from PROGRAM to RUN or
MONITOR mode.
Note A Programming Device can be used to set one or more tasks to go to READY
status when operation is started for task numbers 0 through 31.
A cyclic task that is READY will switch to RUN status and be executed when
the task obtains the right to execute.
A TASK OFF (TKOF(821)) instruction can be used to change a cyclic task
from Disabled status to Standby status.
Activated at the start of

Standby status
Note A task in RUN status will be put into Standby status by the TKOF(821) instruc-
tion even when the TKOF(821) instruction is executed within that task.
Standby status functions exactly the same way as a jump (JMP-JME). Output
status for the Standby task will be maintained.
Instructions will not be executed in Standby status, so instruction execution
time will not be increased. Programming that does not need to be executed all
Right to execute obtained.
