Operands:
S: Delay time, unit: 0.1ms (K1~K1000)
Explanations:
When DELAY instruction executes, in every scan cycle, the execution of the program after DELAY
instruction will be delayed according to the delay time.
Program Example:
When interrupt input X0 is triggered from OFF to ON, interrupt subroutine executes DELAY
instruction first, therefore the program after DELAY instruction (X1 = ON, Y0 = ON…) will be delayed
for 2ms.

Points to note:
1. User can adjust the delay time according to the actual needs.
2. The delay time of DELAY instruction could be increased due to the execution of
communication, high-speed counter and high-speed pulse output instructions.
3. The delay time of DELAY instruction could be increased due to the delay of transistor or relay
when external output (transistor or relay) is specified.
