Operands:

S: delay time (unit: 0.1ms)

Explanations:

1. Range of S: K1 ~ K1,000. See the specifications of each model for their range of use.

2. After DELAY instruction is executed, the program after DELAY in every scan period will execute delay outputs

according to the delay time designated by the user.

Program Example:

When X0 goes from Off to On and generates an external interruption, the interruption subroutine will execute DELAY

for 2ms before executing the next step, X1 = On and Y0 = On.

Remarks:

1. User can define the delay time based on their needs.

2. The delay time may increase due do the influences from communication, high-speed counters and high-speed

pulse output instructions.

3. The delay time of designated external output (transistor or relay) will increase due to the delay on the transistor
