"interface" to my OPC-System

[jopebe]

Hallo to all the specialists!
I have a well running Moeller-Eaton Easy Relay home automation wit an OPC DA server.
I also use IOBroker as a controler for all my MySensors-nodes.
I looked for an software interface to connect both, but I didn't find one.
Now I decided to connect them via an Arduino Mega as an ethernet-gateaway.
So I need only a lot of outputs and inputs with two states.
I found the example-sketch "Relais Actuator", which is very helpful for such a lot of identical outputs.
But I found no way to add lines for the inputs as easy as the outputs.
I added:

#define BIN_1  31  // Arduino Digital I/O pin number for first switch (second on pin+1 etc)
#define NUMBER_OF_BIN 28 // Total number of attached switches
#define BIN_HIGH 1  // GPIO value to write to turn on attached switch
#define BIN_LOW 0 // GPIO value to write to turn off attached switch

In "void before" i added

for (int sensor=16, pin=BIN_1; sensor<=NUMBER_OF_BIN; sensor++, pin++) {
        // Then set relay pins in output mode
        pinMode(pin, INPUT);
        digitalWrite(pin, HIGH);
        // Set switch to last known state (using eeprom storage)
        digitalWrite(pin, loadState(sensor)?1 :0);
        }

in void presentation I addes

for (int sensor=16, pin=BIN_1; sensor<=NUMBER_OF_BIN; sensor++, pin++) {
        // Register all sensors to gw (they will be created as child devices)
        present(sensor, S_DOOR);
    }

The childs appear in "objects" without any state.
I have no idea, how to send the states to the controler for further use in IOBroker.
I don`t know how to create a message-container and send the states.
If anybody could help me to finish my projekt, I were very happy!
