Pin Description
Input EN
Input (only be effective in high potential). Make the clock
pulse generator connected or open via EN input.
Input R Make Output Q be 0 via Input R (Reset).
Parameter T
Time parameter. T is the time length of output to be ON and
OFF.
Output Q
Every time EN changes from 0 to 1, the internal timer begins
to time, and when Time T is up, the output is 1. If EN is held
on 1, timing can be started again, and when Time T is up
again, the output is 0. The cycle operation is continued in this
way until EN is 0 and Output Q is 0. When R is 1, then the
output Q is 0. And when R changes from 1 to 0 and EN is 1,
all the initial status of Q changing from 0 to 1 will start its
cycle.
Output P
If the property pin of the output P is connected with the
properties pin of the SLCD, the parameter of this function
block will be transferred to HMI.

Function Description:
1. Use Parameter T to set ON/OFF time. The assignment range of T is 0.01-99.99
and the time units can be set respectively to hour (H), minute (M), second (S).
2. Input EN enables the clock pulse generator to work. Output Q of clock pulse
generator will flip-flop the status every time the time T elapses, and cycle
operation is continued in this way until Input En is 0. The clock pulse generator
then stops operation and Output Q is 0.
3. EN and R terminals are treated as Status 0 if they are set as X.
4. This function is applicable to generate pulse automatically and to switch ON/OFF.
