This time we will see how to test our sketch to operate with the Arduino YÚN. First of all we could load an OPC Example as Random_yun sketch for test its operation. Note the IP address of the Arduino YÚN Wireles network (192.168.1.5 in this case) and the declared item in the sketch. Now you …

At this time we have to learn how to use the Modbus protocol with the Arduino/Genuino UNO as a slave (server). The device will be connected using the virtual serial port under the USB connection and the PC will act as the client asking to the Arduino device slave to populate information about the digital …

First you have to download Matrikon OPC Explorer from http://www.matrikonopc.es/products/opc-desktop-tools/opc-explorer.aspx Once installed, execute it and try to browse your Arduino OPC Server. If Arduino OPC Server is not shown then maybe you need to configure Matrikon OPC Server to find it. Go to Options and configure Matrikon OPC Server to search for OPC Servers from the …
