(2) Internal contact task processing
•
After the execution of scan program has been completed in the CPU module, the internal contacts that are the start-
up conditions of the task program will be checked and the internal task programs where rising edge or on state has
been occurred will be executed in accordance with its parameter.
(3) Precautions when using an internal task program.
•
The internal task program is executed when scan program has finished its execution. Therefore, though the
execution condition for the internal task program has been invoked in the scan program or task program (time
driven, external) the task (start-up condition) will not be immediately executed but will be executed when scans
program has finished its execution.
•
If execution of an internal task program is requested, the execution conditions will be checked when scan program
has finished its execution. Therefore, if an internal task execution conditions, during ‘One’ scan, has been occurred
and disappeared (if the specified contact has been turned from OFF to ON, and then from ON to OFF) by scan
program or (time driven or external) task program the task will not be executed as the execution condition can not
be detected at the time that execution conditions are being checked.
1) When an action must continuously be executed according to the related contact point set as a start-up
condition, select a level.
6) Execution of high-speed task program
GM7U series uses general digital input contact point to count high-speed pulse, not a separate high-speed pulse input
module. Setting a task (startup condition) as the same with the one of the high-speed pulse input will be explained.
(1) Conditions to be set for a task
y
Set the priority on the tasks that are startup conditions for the task program to be executed. Then a task number
will automatically be added in the priority order.
(2) Processing the high speed counter task
y
When CHSC_SET F/B of the program assigns a set value, the task program whose set value matches with the
counted value of the pulse that is input in a high speed is executed.
(3) Precautions for using high speed counter task program
y
Even though the operation is in the PAUSE mode, counted value rises. However, the task program is not executed
although the counter value reaches to the set value.
