  • We're experiencing challenges connecting to OPC Servers with Mango and would need to know where to get more documentation. Not all OPC Servers require authentication.


  • Hi Gordoe,

    Good question! Alas, I'm not too sure. i can tell you that the OPC module is using the org.openscada OPC version 0.9 library to actually do the OPC protocol. I have very limited experience with OPC devices. It looks like you could modify a Mango/bin/ext-available script to set the log level for the logger in the library to a lower level by change its JAVA_OPTS to -Dorg.slf4j.simpleLogger.defaultLogLevel=debug or put a config file someplace: https://stackoverflow.com/questions/14544991/how-to-configure-slf4j-simple

    I'm not sure I found the ideal place to explore v0.9 of the source code for the library on the web.
