1 TaskIntroduction
In residential house, the following functions shall be controlled manually or automatically:
Blinds
Roof hatch
Interior and exterior lighting including panic switch
Heating
Garden watering
The manual or automatic mode can be selected via the selection button.
Depending on time and day, the blinds are automatically opened or closed and thegarden watering is switched on or off.
Depending on the temperature, the roof hatches can be opened or closed and theheating switched on or off.
If the maintenance mode is set for the blinds, manual or automatic closing isblocked.
The states of the respective house functions are displayed on a text display.
2 Solution
2.1 Overview of the general solution
Figure 2-1
In the automation solution, one LOGO! 0BA7 (1) is used as master and one asslave, which both communicate with each other via a compact switch module (6).
One PT100 (9) and one PT1000- (10) temperature sensor each are connected tothe RTD expansion module (5), and they are used to control the temperatures indifferent building areas. Further inputs and outputs of the configuration can beadded at any time via DM16 24R (2) or DM8 24R (3) expansion modules. Theblinds (14) and the roof hatch (12) can be opened or closed manually via buttons.
The exterior and the interior lighting can be switched on and off via buttons (12). Alllights are switched off via a central off button. For each button in the house, a panicfunction is configured so when pressing longer than 3 seconds, all lights areswitched on for a certain amount of time and switched off with automatic time delay
or pressing the button for another 3 seconds.

An FI protective switch (18) provides the necessary security. Additionally, thepower supply for the first, second or third line of the distribution box can beswitched off via line protection switch (16, 17).
Via LOGO! TD (8), the blinds, the lights and the roof hatch can be controlledcentrally and the automatic mode can be switched on and off. Switching themaintenance mode and garden watering on and off, as well as changing thesetpoint values for the heating is possible.
Advantages/Benefits
Simple execution and clear operation and monitoring of a house control withLOGO! OBA7 and LOGO! TD
Adjustable automatic function of the house control with times and days, whichcan be adjusted individually
Protection of the blinds for maintenance works
Excellent energy efficiency by monitoring the heating depending on the roomtemperature and the given setpoint value
Central house control via LOGO! TD
Presence simulation when absent through automatic opening and closing theblinds via a random generator
Simultaneously switching all lights on and off via panic buttons
Control of several areas and functionalities of a house control via stillunassigned inputs and outputs

Function description
For each blind, a 0.5 seconds pause for the direction change was programmed for protecting the motor against direct rerouting.
In manual mode, the blinds are operated via buttons and LOGO! TD (see Table 3-1,Table 5-1 No. 3, and Table 5-2).
With LOGO! function block “Astronomical clock” the blinds are, in automatic mode,moved up at sunrise and moved down at sunset during the week. On the weekend,the blinds are moved up at 08:00 h and down at 20:00 h. A random generator candelay the time of automatic opening and closing up to 30 minutes. Even though thehouse is empty, this makes it seem that somebody is in the house.
In maintenance mode, the blinds move up. Closing the blinds only becomespossible again when the maintenance mode is deactivated.
In configuration mode, the parameters of the function blocks (“weekday”, “weekend”,“astro.cl”, “random”) can be changed on the LOGO! display and LOGO! TD.

Function description
For each roof hatch, a 0.5 seconds pause for the direction change wasprogrammed for protecting the motor against direct rerouting.
In manual mode, the roof hatch is exclusively operated via the button.
In automatic mode, the “aut.roo” (analog threshold value switch) function blockcontrols the roof hatch depending in the temperature.
In configuration mode, the parameters of the “aut.roo” function block can bechanged on the LOGO! display and LOGO! TD.
Note When using a rain sensor (see LOGO! Set 11), the roof hatch is closeddepending on the weather.

The heaters are switched on and off via the function blocks “heater1” (AnalogComparator) and “heater2” (Analog Comparator).
Note In the LOGO! basic device (master), the standard setting for two analog inputsare used so the RTD expansion module has the inputs AI3 and AI4.
3.4 Garden watering
Function description
In manual mode, the garden watering is operated via LOGO! TD (see Table 5-1, No. 8).
In automatic mode, the garden watering is switched on in the morning at 09:00 h and in theevening at 20:00 h for 10 minutes.
In configuration mode, the days and times of the weekly timer switch (function block “watering”)can be changed on the LOGO! display and LOGO! TD.
Note When using a rain sensor (see LOGO! Set 11), the garden watering issuppressed depending on the weather.
