Description

16ch Binary Input (potential-free)

The binary input has 16 inputs available and is used to connect eight conventional push-buttons or floating contacts such as window or relay contacts. There is one status LED for each input. In addition, the input status is sent to the bus. A separate power supply is not necessary


Technical Data:

  • Operating voltage:         KNX Bus voltage <10mA
  • Installation type:             Top Hat Rail mounting
  • Number of Inputs:           16
  • Number of S0-Inputs:      4 (CH13 - CH16)
  • Input polling:                    with 100ms, 300ms or 500ms
  • Typ of Inputs:                   potential-free / floating contacts
  • Max. cable length:           30m tested (more possible)
  • input voltage:                  5V
  • Max. input voltage:          24V (absolute rating, for <1min)
  • Max. input current:          10mA
  • The device makes a contact supply voltage (5V) which is not electrically isolated from the bus voltage!
  • x-Inputs can configure to a "room" ("room"-GA can show if one of the windows is open in the room)


Hardware

Software

What you need

  • Arduino IDE (link)
  • Arduino Code for 16CH Binary Input
  • XML-File for 16CH Binary Input
  • KONNEKTING SUITE (link)


Arduino Code

Libs

#include <KonnektingDevice.h>
#include "kdevice_KNX_Bineareingang_Multi.h"  -> erzeugte lib aus Konnekting
#include "Timer.h"
#include "EEPROM.h"
#include "S0_Schnittstelle.h"
#include <RTCZero.h>
#include <Wire.h>
#include <PCF8575.h> // Required for PCF8575

Debug Config

Hier hat man Möglichkeiten bestimmte Funktionen zu aktivieren/deaktivieren

// I2C-MODE (enable for normal mode)
#define I2COFF // comment this line to disable I2C mode
// DEBUG-MODE (for normal mode without debugging you must deactivate the function)
#define KDEBUG // comment this line to disable DEBUG mode
// Anzeige-Platine (enable if you use the Status LED PCB)
#define ANZEIGE_Platine

KNX Serial Config

Hier wird das Serial-IF zum KNX-Bus konfiguriert

#ifdef __AVR_ATmega328P__
#define KNX_SERIAL Serial // Nano/ProMini etc. use Serial
#elif ESP8266
#define KNX_SERIAL Serial // ESP8266 use Serial
#else
#define KNX_SERIAL Serial1 // Leonardo/Micro/Zero etc. use Serial1
#endif

RTC Config

Jeden Tag um 0UHr werden alle Daten ins EEPROM geschrieben

/* Create an rtc object */
RTCZero rtc;
/* Change these values to set the current initial time */
const byte seconds = 0;
const byte minutes = 00;
const byte hours = 00;
/* Change these values to set the current initial date */
const byte day = 1;
const byte month = 1;
const byte year = 17;


define IO Config

#define PROG_LED_PIN    A2
#define PROG_BUTTON_PIN A1
#define LED_YELLOW      25     
#define SAVE_PIN        38
#define MAX_CH          15

Room classification

Die Raumerkennung funktioniert als 16Bit Wert und jedes Bit ist ein Input. Möchte man also alle 16 Inputs zusammen als "Zimmer" definieren, dann wäre das:
b1111111111111111 = 65535
oder frei, Inputs wären hier: 1,5,6,10,14,15
b1000110001000110 = 35910
Die Dezimalwerte kann man in die Suite eingeben, beim parameterisieren werden diese Werte ins EEPROM geschrieben. Bei jedem Start werden die Daten ins RAM geladen und decodiert.
Aktuell können so 5 "Zimmer" definiert werden

HW Documentation

Circuit diagram

One VCC Output-Pin shares two Input-Channels. Because of that always two Channels will monitoring together.

S0 interface Up to four Inputs can configure to an S0-interface. possible CH are Ch13 - Ch16 note: If you configure only one Ch to an S0-Interface on an VCC-Output pair, then the output of the other CH can not be switched off, because the VCC-Output voltage supply always both Channels.


16Ch Input
12Ch Input + 4Ch S0-Interface

State Machine

START -> Loop over all Channels (activation Outputs x + y -> readout inputs x + y -> update Status LED -> deactivation Outputs x + y)
