(2) Enable interrupt TASK_EI
This FB is used to enable interrupt of a task. Specify a task level (0 to 4, 10 to 19) for which interrupt is enabled by a bit pattern.
1) Symbol
TASK_EI
LEVEL
3) Function
• This instruction is used to enable interrupt of the task level that has been disabled by the “TASK_DI” instruction.
• Set ON the bit position of the task level (0 to 4, 10 to 19) for which interrupt is enabled by WORD-type data of “LEVEL.”
Interrupt is enabled for the corresponding task.
• The interrupt disabled state of each task is output.
• Even if the bit of WORD-type data of “LEVEL” is turned from ON to OFF, the interrupt enabled state continues. To disable
interrupt, use the “TASK_DI” instruction.
2) Description of FCT terminals
Parameter Data type Description
LEVEL WORD
Specify the bit position of the target task level. (ON: Enable, OFF: No operation)
* Set ON the bit position. of a task for which interrupt is disabled (0 to 4 or 10).
You can set ON multiple bit positions
Interrupt is disabled only in the task of the specied bit.
