Function
Function
I/O refreshing and the user program are executed in units that are called tasks.
Tasks are used to specify execution conditions and execution priority.
Periodically executed tasks
Conditionally executed tasks
Maximum number of primary periodic tasks: 1
Maximum number of periodic tasks: 2
Maximum number of even tasks: 32
When active even task instruction is executed or when condition expression for variable is met.
