The Integral Real-Time Clock S5-100U
12.3.2 Setting the Prompt Time in DB1
How to set the prompt time in DB1
1.
Perform an overall reset on the programmable controller.
2. Generate DB5 with DW0 to DW21.
3. Output default DB1 to the programmer.
4. Overwrite the comment characters (#) with a blank space.
5. Use the cursor to jump into the CLP parameter block.
6. Enter the example.
- Set the clock to the following prompt time: Thursday, December 17, 1992, 8:00 o’clock.
Figure 12-3. Example: Setting the Prompt Time in DB1 to Thursday, December 17,
1992, 8:00 o’clock
The clock data is stored in data block 5 beginning
with data word DW0. The status word is located in
flag word MW 102.
The clock is updated when the programmable
controller is in the STOP mode. The clock time is
saved in the clock data area. See Table 12-3.
After the parameter for TIS, enter the weekday,
date and time to initiate the prompt time.
You can enter the parameter for the clock mode.
The clock runs in the 24-hour time mode.
