11.14.2 Time Channels, Intervals, and Timers
Time Channels
It is possible to assign the output of the interval and/or timer functions to time channels 1–3. It is possible to use the time channels
to control on/off type functions, for example relay outputs or digital inputs. To configure the on/off logic of the time channels, as-
sign intervals and/or timers to them. A time channel can be controlled by many different intervals or timers.
Assigning intervals and timers to time channels is flexible. Every interval and timer has a parameter with which to assign them to a
time channel.

Illustration 73: Assigning Intervals and Timers to time Channels
Intervals
Use parameters to give each interval an ON Time and OFF Time. It is the daily active time of the interval during the days set with
parameters From Day and To Day. For example, with the parameter settings below, the interval is active from 7 am to 9 am from
Monday to Friday. The time channel is like a digital input, but virtual.
• ON Time: 07:00:00
• OFF Time: 09:00:00
• From Day: Monday
• To Day: Friday
Timers
Use the timers to set a time channel as active for a period with a command from a digital input or a time channel.
In the following figure, the activation signal comes from a digital input or a virtual digital input, like a time channel. The timer counts
down from the falling edge.
