1 TaskIntroduction

For street lights, factors like remote control, networking and potential energy savingare becoming increasingly important.With this in mind, the street lights in a street shall be automatically switchedon and off at sunset and sunrise. In addition, it shall be possible to insert a switch-on time for the street lights via SMS, or manually on site.

2 Solution2.1 Overview

Schematic layoutThe figure below shows a schematic overview of the most important components ofthe solution:Figure 2-1

Time-of-daysynchronizationNTP server

In the automation solution, the street light is controlled with a LOGO! 8 connectedto a LOGO! CMR.Setting a manual street light control (user-defined mode) or an automatic control(astro clock mode) can be performed via SMS or LOGO! TDE.In astro clock mode, the street light is switched off in the morning and back on atnight using the “Astronomical clock” function.In user-defined mode, a user-defined time of day can be entered via LOGO!display or LOGO! TDE at which the street light shall be switched on, the day after.The time of day of the LOGO! controller is synchronized with an NTP server usingLOGO! CMR so LOGO! constantly has the correct UTC time.

3 Mode of Operation3.1 Switching on the street lights by entering the time

manually (user-defined mode)

Determine manually, via SMS or the LOGO! TDE, at which time of day the streetlights shall be switched on the day after.The time value is written to function block “Set time” via variable address “VW6”and further processed in the program.Figure 3-1

A valid format for the time input is the hours as numerals “1-24” and the minutes asnumerals “0-59”. If, for example, the user-defined time of day “11:30 h” shall be set,the value “1130” must be entered here via SMS, LOGO! display, or LOGO! TDE.The correctness of the entered time value is verified in the LOGO! program bymeans of analog function blocks (analog comparators, analog MUX, etc.).If an invalid time format is entered (e.g. “2430”), a warning message is output viaSMS, and locally on LOGO! display or LOGO! TDE, and the astro clock mode isautomatically activated.As soon as a valid time format is inserted, the user-defined mode is automaticallyactivated again.

rese

rved

Note Please note that for the time of day value “00:00” h, the analog value “2400”must be entered. Entering the value “0000” as analog value prompts a warningmessage stating that the time format is wrong.

3.2 Function mechanism of the user-defined time of dayinput

The time base for setting the switch-on time for the street lights is implementedwith a weekly timer and a wiping relay.The analog value written to the LOGO! program as time of day input is furtherprocessed as pulse width parameter (TH) via the wiping relay.For switch-on time “1130”, for example, the calculated pulse duration (TH) is 690minutes. Converting the 690 minutes yields 11 hours and 30 minutes.

Figure 3-2

Each day at 00:00 h, the weekly timer sends a pulse for one minute. As soon asthe wiping relay detects this pulse at the “Trg” input, the pulse width (TH) iscounted down in minutes (690 minutes in this example).After the pulse width (TH) of the wiping relay has elapsed, the street lights areswitched on.

Note The pulse of the weekly timer for counting the pulse width is sent at 00:00 hevery day by the wiping relay. When entering a user-defined switch-on time asan analog value, this value will be counted down as pulse width (TH) by thewiping relay on the following day. The inserted switch-on time for the street lightstherefore applies to the following day.

3.3 Automatic street light control (astro clock mode)

When setting the astro clock mode for controlling the street lights,street lighting is automatically switched off at sunrise and switched on at sunset.

3.4 Changeover between astro clock mode/ user-definedmode:

Changing between user-defined and astro clock mode is possible at any time viaSMS and LOGO! TDE.

3.4.1 Mode change via LOGO! TDE

With LOGO! TDE, the mode is changed by pressing the F1 button.

3.4.2 Mode change via SMS

Changing the mode via SMS requires generating a trigger for the pulse relay(function block B042):

Figure 3-3

A random analog value is written to analog network input NAI2 via SMS (at leastvalue "1"). As soon as the analog value has been entered, the threshold trigger(function block B007) switches to “true” and forwards the trigger to the currentpulse relay (function block B042).

Figure 3-4

If at a later point in time, the mode shall be changed again, another value must bewritten to analog network input NAI2 to generate a new trigger.

To enable writing a new value to analog network input NAI2, it must first be reset.Analog network input NAI2 is reset by analog MUX (function block B015) via outputAQ, to which the same address VW8 has been assigned by address network inputNAI2 via the parameter VM mapping table.As soon as a new value is written to analog network input NAI2, output AQ is set to“0” after 2 seconds by the analog MUX (function B015). This resets the analognetwork input NAI2 automatically back to “0”.

4.3 Configuring time-of-day synchronization from LOGO!CMR via NTP server

LOGO! CMR enables synchronizing the time of day using different methods (GPS,GSM, NTP server) and forwarding it to LOGO! 8.The correct UTC time is therefore always set in LOGO! which is very important inapplications where a timer, for example, is used.In this application example it is ensured by the time-of-day synchronization thatstreet lighting is controlled at the right time of day via the astronomical clock.

The tables below describe the settings to be made in the web interface (WBM) of LOGO! CMRto enable sending or receiving an SMS with LOGO! CMR.

Note In the completed configuration file for LOGO! CMR, also offered in thisapplication example for download, the settings for the time-of-daysynchronization of LOGO! CMR via NTP server have already been made.

Further information, on how to load the completed configuration file into LOGO!CMR is available in Chapter 5.3.2.

The NTP server used in this example is a free to use NTP server. Siemensdoes not provide this service.

Alternatively, another NTP server can also be used.If necessary, check the respective license terms of the NTP server for yourapplication purpose.
