OPC UA Client

note this driver will be deprecated in a future release we recommend using docid\ g5sby5tl8xu28ch4eluig review the following information for setting up and configuring the opc ua client manufacturing connect edge compatible series compatibility parameter compatible items driver type ethernet validated devices/series used to subscribe data from opc ua servers only sends a message to the broker if the value changes at the server level subscription interval is defined at the driver level and does not have a polling interval at the tag level replaced with gen 2 driver docid\ g5sby5tl8xu28ch4eluig note the opc ua client does not connect to the server with the basic256sha256 se security policy supported servers opc ua client it provides better performance compared to other opc ua clients opc ua client with new design supports both poll and subscription mode set up the plc device in manufacturing connect edge devicehub configure the following parameters when you docid\ rfvijdxz7dbad8mwbisma with this driver update default values to the specific set up of your device parameter value type opc ua driver opc ua client network address the device ip address network port 4840 certificate auto generated private key auto generated configure the list of registers browse for tags to add to this freetag device see docid\ olxxodrwnlm ikp2gps 4 to learn more alternatively, when you docid\ h5heqicxrcy3nch9kbg9i , for register name map the opc server tags to the client using this format ns=1;s=tagname example ns=2;s=demo static scalar boolean the following data types are supported int32 bool sbyte byte int16 uint16 int32 uint32 int64 uint64 float32 float64 string dump desc refer to the following tag parameters tag parameters name enter a name based on this format ns=1;s=tagname example ns=2;s=demo static scalar boolean value type select a data type from the drop down list tag name enter a name for the tag description (optional) enter a description for the tag tag formula enter a formula for the tag to process the generated data two variables are permitted value (current tag value) and timestamp (current tag unix time in milliseconds) the following math functions are available sin cos sqrt tan power power( x ) performs the operation 10^x log log( x ) is the natural logarithm (the logarithm is in base e ) exp exp( x ) performs the operation e^x only publish on change of value select the checkbox to customize nats messages to be published only when the value parameter changes from a previous value to a new one change of value only applies to boolean, numeric (such as int or float), and simple string data types it does not apply to complex types, such as json or array poll once topics will not be affected by change of value settings these topics will still only see a single message meta data metadata summarizes basic information about data this feature allows you to define key value pair data for the device output payload later on it can then be used to find, use, and reuse particular instances of data note if you use special characters in meta data key names, the special characters are replaced with underscore characters in the payload this can cause two key names to be combined into one for example, configuring the key names a b and a&\&b will cause only one key name to be created (a b)
