Delay Word
Explanation:
After the instruction DELAY is executed, the execution of the program following the DELAY is
delayed for a period of time specified by users.
The unit of S is 0.1 milliseconds.
Example:
When X0.0 is ON, the instruction DELAY is executed. The execution of the program following
DELAY is delayed for two milliseconds. That is, Y0.0 is ON and the states of Y0.0~Y0.15 are
refreshed two milliseconds after the instruction DELAY is executed.
Output Y0.0
T=2ms
Input X0.0
Additional remark:
1. If S I less than 0, there is no delay.
2. If S is larger than 1000, the instruction is not executed, SM0 is ON, and the error code in SR0
is 16#2003.
3. Users can adjust the delay according to the practical condition.
4. The delay will increase due to the communication or other influences.
