05 DI Disable Interrupt
OP Descriptions Program Steps
N/A
No contact to drive the instruction is required.
DI instruction disables PLC to accept interrupts.
When the special auxiliary relay M1050 ~ M1059 for
disabling interruption is driven, the corresponding
interruption request will not be executed even in the range
allowed for interruptions.
DI: 1 step

Explanations:
1. EI instruction allows interrupting subroutine in the program, e.g. external interruption, timer
interruption, and high-speed counter interruption.
2. In the program, interruption subroutines are enabled between EI and DI instructions. If there is
no section requires to be interrupt-disabled, DI instruction can be omitted.
3. Interrupt subroutines must be placed after the FEND instruction.
4. Other interrupts are not allowed during execution of a current interrupt routine.
5. When many interruptions occur, the priority is given to the firstly executed interruption. If
several interruptions occur at the same time, the priority is given to the interruption with the
smaller pointer No.
6. Any interrupt request occurring between DI and EI instructions will not be executed
immediately. The interrupt will be memorized and executed when the next EI occurs.
7. When using the interruption pointer, DO NOT repeatedly use the high-speed counter driven by
the same X input contact.
8. When immediate I/O is required during the interruption, write REF instruction in the program to
update the state of I/O
Points to note:
Interrupt pointers (I):
a) External interrupts: 8 points including (I000/I001, X0), (I100/I101, X1), (I200/I201, X2),
(I300/I301, X3), (I400/I401, X4), (I500/I501, X5), (I600/I601, X6) and (I700/I701, X7) (00
designates interruption in falling-edge, 01 designates interruption in rising-edge)
Timer interrupts: 2 points including I605~I699 and I705~I799 (Timer resolution = 1ms), Timer
interrupts: 1 point including I805~I899 (Timer resolution = 0.1ms), available for SE,
ES2-E/EC5, for other modules, this function is available for modules with firmware V2.00 or
later.
