Mode of Operation

Time switch function
The time switch function in LOGO! consists of weekly and yearly timers and offers
the following scope of functions:

Standard times:
Switching on and off on certain days of the week, at certain times.

Event times:
Switching on and off on a certain date, at a certain time (e.g. for evening
events).

Times for suppressing the time switch function:
Date and time at which the standard and event times are inoperative, e.g.
during school holidays.

Central switching on and off:
Manual switching on and off, regardless of the time settings, e.g. for
maintenance work.
Mounting into KNX
Via the LOGO! communication module CMK2000, the time switch function of the
LOGO! is integrated into a KNX system.
Via configurable communication channels of the LOGO! CMK2000, the data
between the LOGO! and the KNX devices are exchanged bi-directionally.
In this application example, a 3-Gang Button with status LEDs is used as KNX
device. A status LED indicates the status of the time switch function.
Operation
The time switch function is configured by the user.
This requires no special programming knowledge. The following options are
available:

Displaying message texts with time and date parameters at the LOGO! TDE

Displaying message texts with time and date parameters using the integrated
web server of the LOGO!
For users with programming experience, the following additional options to
configure the LOGO! time switch function are available:

In LOGO! Soft Comfort during commissioning

Configuration mode at LOGO! display
Central switching on and off is done via configured KNX buttons, digital inputs of
the LOGO!, or function buttons of the LOGO! TDE.
LOGO! TDE is an optional component whose functions (message texts and
function buttons) can also be used via the web server. You can also use a LOGO!
basic device without display.
