Спасибо за своевременный ответ. К сожалению, не смог ответить сразу. Я загружаю код из примеров блиотеки OPC "Uno LED". После установки компонентов OPC ситуация изменилась. Теперь ошибка: "Этот OPC сервер не содержит публичных тегов".
Сервер пишет следующее:
01.06.2016 11:21:12 > Connected client
01.06.2016 11:21:12 > Asking for available OPCItems from ArduinoSerial0
01.06.2016 11:21:13 > Disconnected client Simple-Editor DA Client
На всякий случай приложу код:
#include <OPC.h>
#include <Bridge.h>
#include <Ethernet.h>
#include <SPI.h>
/*
* Declaring the OPC object
*/
OPCSerial aOPCSerial;
/*
* set led status from OPC Client
*/
int ledPin = 13;
/*
* create a callback function for the OPCItem
*/
bool callback(const char *itemID, const opcOperation opcOP, const bool value){
static bool ledValue = false;
/*
* if operation is a write command from OPC Client
*/
if (opcOP == opc_opwrite) {
ledValue = value;
if (ledValue)
digitalWrite(ledPin, HIGH);
else
digitalWrite(ledPin, LOW);
}
else
/*
* read the led status
*/
return ledValue;
}
void setup() {
Serial.begin(9600);
pinMode(ledPin, OUTPUT);
/*
* OPC Object initialization
*/
aOPCSerial.setup();
/*
* led OPCItem declaration
*/
aOPCSerial.addItem("led",opc_readwrite, opc_bool, callback);
}
void loop() {
/*
* OPC process commands
*/
aOPCSerial.processOPCCommands();
}
Попробовал снова без режима администратора, на этот раз сервер отреагировал следующим образом:

Стоит добавить, что использую Arduno Mega. При компилировании появляются ошибки, но скетч все равно загружается. Приведу код ниже, если вдруг поможет

Пытались ли Вы добавить не только bool-теги, но и теги с другими типами данных (например int)? В этой теме (https://simple-scada.com/forum/index.php?topic=114.msg728#msg728) есть много примеров. И ещё, удается ли увидеть теги утилитой ItemProperty (https://www.simple-scada.com/downloads/ItemProperty.rar)?
