1. Real time window determination TZCP
1. Real time window determination TZCP
1.1. Instruction Description
The instruction will read the current time from the hardware clock and compare it with the given time window (a time period consisting of start and end times), and store the comparison results of each situation in the specified bit register group.
Assuming to output to Y000, Y001, Y002, Y000=1 when the current time does not enter the time window, Y001=1 when entering the time window, and Y002=1 when exceeding the time window.
If BCD format is selected in [PLC Settings]=>[Other]=>[Real time Clock Format], all date and time values must be encoded in BCD format (for example, 8211 represents 2013) Please refer to the table below.
| T (Dn-Dn+7) | Description | Data |
|---|---|---|
| 0 | Year (2000-2099) | Current Year |
| 1 | Month (1-12) | Current month |
| 2 | Date (1-31) | Current Date |
| 3 | Hour (0-23) | Current Hour |
| 4 | Minutes (0-59) | Current minute |
| 5 | seconds (0-59) | current second |
| 6 | 00 | Reserved |
| 7 | What day of the week (0-6) | The current day of the week, 0=Sunday |
