    Hello

    first of all i want to congratulate on this project !
    Im trying to connect my arduino MEGA 2560 board with Wonderware InTouch. Im using OPC Arduino 1.9 version, OPC library is 1.7, IDE is 1.8.2 .
    I had problem with compailing sketch MEGA for OPC. When i try to upload it on board there is some error message: OPCItemType was not declared in this scope.
    Code which i tried to upload is :

    code code:/*
    * A generic sketch for use with the Arduino OPC or Visual OPC Builder from www.st4makers.com
    */
    #include <OPC.h>
    #include <Bridge.h>

    #include <SPI.h>

    OPCSerial myArduinoMEGA;

    opcAccessRights digital_status_input[54], analog_status_input[16];

    bool readwrite_digital(const char *itemID, const opcOperation opcOP, const bool value)
    {
    byte port;

    OPCItemType aOPCItem = myArduinoMEGA.getOPCItem(itemID);

    port = atoi(&itemID[1]);

    if (opcOP == opc_opwrite) {
    if ((aOPCItem.opcAccessRight == opc_write) || (aOPCItem.opcAccessRight == opc_readwrite)) {

    if (digital_status_input[port] != opc_write) {
    pinMode(port, OUTPUT);
    digital_status_input[port] = opc_write;
    }

    digitalWrite(port,value);
    }
    }

    if (opcOP == opc_opread) {

    }

    return digitalRead(port);
    }
    }
    }

    {
    byte port;

    OPCItemType aOPCItem = myArduinoMEGA.getOPCItem(itemID);

    port = atoi(&itemID[1]);

    if (opcOP == opc_opwrite) {

    Hello,
    no, i didnt resolve it. I only had success with UnoLED sketch, after upload it on mega2560, i was able to control LED on mega from Wonderware app. But this above, shows error like i explane.
    Best Regards,

    Hello,
    i resolve the problem by updating two files: OPC.h and OPC.cpp (i download it from your folder on https://github.com/SoftwareTools4Makers/OPC).
    So, i download MEGA sketch from that folder too, and upload it on arduino well.
    I succesfully add items on my SCADA app, i use Wonderware InTouch, but i have problem with Digital I/O.
    Button going in ON and OFF position byself every few second. Only digital I/O D13, where is LED integrated works fine, but others digital I/O going in ON and then after few seconds in OFF position byself.
    I dont know why, maybe is some problem in sketch, i will try to find out what happens..
    Best regards,
    Nikola

    Yes, sure the problem is in the sketch. I havent time to test it in deep. If you detect any issue, please let me know

    Hello again,
    i dont want to open new topic, i think this one have some same issues:
    do you have maybe sketch for MEGA 2560 OPC through Ethernet?
    I connected W5100 shield on my MEGA 2560 board, and im trying to connect it with opc but i have problem.
    When i use sketch from library (EthernetShieldR3, EthernetShieldLED…) i cant reach opcItems (look at attached file). I use latest update of everything. I can ping ip of shield, but nothing of items.

    Best regards,
    Nikola

    It was my fault. I made constantly mistake with IP address. I was write IP address which i found in Control Panel — Network manager … In details of Local Area Network, there was set one IP addresse (10.0.0.12), and i always put that IP in arduino sketch and that didnt work. After i written address 10.0.0.13 , everything was fine.
    Maybe if there is somebody like me who is not good in this communications, this answer will help. 🙂

    Best regards,
    Nikola

    If someone use ethernet shield on arduino Mega 2560, here is modified generic sketch for use with Mega and Arduino OPC server. Find it below:

    Thank you

    I will take a look and incorporate it in the examples library if you dont mind

    all the best and thanks

    Yes, ofcourse.
    Im going to test communication between arduino and SCADA and reliability of arduino as well. I will try to improve it and if i find out something, i will share here.
    Best regards,
    Nikola
