1.2 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.

2.3.1 Basics
Week timer
Every week timer has three setting cams via which you can parameterize a time
slot each. Via the cams, you can set the switch on and off times (see Table 3-1).
If the output has not yet been set, the week timer will switch it on at a switch-on
time.
If a switch-off time is configured, the output of the week timer will be reset at the
switch-off time.
The switching state of the week timer depends on all three cams, No 1, No 2 and
No 3.
Figure 2-2: Week timer function block
Yearly timer
On certain dates, the yearly timer switches the output on or off.
The switch-on time indicates month and day, on which the timer is set.
The switch-off time indicates month and day, on which the timer is reset again.
(see Table 3-2).
The function offers two repeat patterns:
Yearly:
Timer output switches on every year at the specified month and day of the
switch-on time and remains switched on until the specified month and day of
the switch-off time.
Every month:
Timer output switches on every month at the specified day of the switch-on
time and remains switched on until the specified day of the switch-off time.
The switch-on year specifies the first year in which the timer will be activated.
The switch-off year specifies the last year in which the timer will be switched off.
Figure 2-3: Yearly timer function block
Internal clock buffering
The internal clock of a LOGO! 8 is buffered by an accumulator and continues to run
in the event of a power supply failure.
The buffering time is influenced by the ambient temperature. At 25 °C (77 °F), it is
around 20 days.

1. Time-controlled switching on and off
The combination of different switching times expands the time switch function as
follows.
Standard switching time
Via the week timer function block "B002 StandardTime”, the standard switching
time is defined.
Via the function block, it is set, on which weekdays and at which time the time
switch function switches the output Q1 on and off.
Event switching time
By linking the week timer "B001 EventTime" and yearly timer "B008 EventDay"
function blocks, an event switching time is defined.
Via the function blocks, the date and time is set for when the time switch function
switches the output Q1 on and off.
Figure 2-5: Blocks for time-controlled switching on and off
2. Suppress switching on at certain times
With the yearly timers “B006 SummerBreak”, “B020 EasterBreak” and “B049
WinterBreak”, a time period (e.g. holidays) can be defined during which the switch-
on via the standard switching times is suppressed.
With the weekly timer “B017 TimeLock”, it can be defined, on which weekdays and
at which time the switch-on via the standard switching times is suppressed.
The event switching times are not suppressed and continue to switch. This allows a
planned switch-on and off, despite the suppressed standard switching times.

3. Central switching on and off
1. Via the input I1, the function key F1 or the flag M50 (signal from the KNX), the
output of the time switch function is switched on centrally.
2. Via the input I2, the function key F2 or the flag M51 (signal from the KNX), the
output of the time switch function is switched off centrally.
The central switching on and off will be overwritten with the next impulse from the
set switching times.

4. Adjust switching times in the message text
To comfortably adjust the switching times, the switching program contains
message text blocks. The content of the message texts is displayed at the LOGO!
TDE or in the web server (LOGO! TD).
Note
In this application example, the display via the LOGO! TD is preferred, whereby
more characters per line are available in the message text than via the LOGO!
display.
Additionally, the function keys and message texts of the LOGO! TD can be used
via the web server.
Figure 2-8: Message text blocks
In the message texts, individual parameters of the weekly and yearly timers are
inserted. The parameters are clearly named for an unequivocal identification.
During operation, an operator can select and change a parameter via the message
texts at the display or via the web server.(see 4.1.2).
