3) Task program
(1) Function
•
In order to process internal/external signal, which occurs periodically, or non-periodicity the task program
temporarily stop the operation of scan program and processes first the corresponding function.
(2) Types
•
Task programs are classified into four types as below.
▶
Time driven task program : Up to 8 programs are applicable
▶
Single (internal) task program: Up to 8 programs are applicable
▶
Interrupt (external) task program: Up to 8 programs are applicable
High speed counter task program: Up to 4 programs are applicable.
▶
•
Time driven task program
▶
The program is executed by the time internal set before.
•
Single (internal) task program
▶
The corresponding program will be executed at the rising edge and on state of internal contact
in the program.
▶
The detection of the start up condition will be executed after the scan program has been processed.
•
Interrupt (external) task program
▶
The program is executed according to the external signal a input to the interrupt module
•
High-speed counter task program
The program is executed according to speed level.
▶
1) Refer to section 5.4.3 “Task” for details of task program.
2) GM7U series use separate digital input contact to execute interrupt signal. Refer to section 5.4.3 “Task” for
details of task program.
