28 training simulation time interrupt organization block
Question 1: "D_TOD_TD" What is this? See 107 books
A: D_TOD_TD IEC function FC IN1 is beginning to define the date and time of interruption,
TOD # 8: 0: 0.000 milliseconds seconds respectively minutes
Issue 2 "QRY_TINT" inside the state is how to define the word?
Because behind me I use MB9 bit 4 and 2 to monitor the inside PLCSIM

Question 3 has generated local variable 20 bytes organization block OB1 of how to view?
In the video CD in the name of the time interrupt organization block applications.
The video function is completed
By function "QRY_TINT" and "D_TOD_DT" set interrupt time. For example, the time now is
2020/2/8 1:06 I can set 2020/2/8 1:00
Then the time has generated the interrupt.
At the same time generates an interrupt function "SET_TINT" which set 1min, the interrupt time is 1 minute
An interrupt is generated in block OB10 1min tissue to which increments by one MW2
