Solution:
Set up two intervals: one for weekdays, and one for weekends. A timer is also needed for activation outside the
normal office hours. The example configuration is completed as follows:
1. Interval 1 (used for the weekdays)
– Set ON Time (P3.11.1.1) to a value of 07:00:00.
– Set OFF Time (P3.11.1.2) to a value of 17:00:00.
– Set From Day (P3.11.1.3) to a value of Monday.
– Set To Day (P3.11.1.4) to a value of Friday.
– Set Assign to Channel (P3.11.1.5) to a value of Time Channel 1.
2. Interval 2 (used for the weekends)
– Set ON Time (P3.11.2.1) to a value of 09:00:00.
– Set OFF Time (P3.11.2.2) to a value of 13:00:00.
– Set From Day (P3.11.2.3) to a value of Saturday.
– Set To Day (P3.11.2.4) to a value of Sunday.
– Set Assign to Channel (P3.11.2.5) to a value of Time Channel 1.
3. Timer 1 (used for the override operation outside of normal office hours)
– Set Duration (P3.11.6.1) to a value of 1800 (30 minutes).
– Set Assign to Channel (P3.11.6.2) to a value of Time Channel 1.
– Set Timer 1 (P3.5.1.18) to a value of DigIN Slot A.1.
4. Control Source (location of the start/stop)
Set Control Signal 1 A (P3.5.1.1) to a value of TimeChannel.1.
