DeviceHub Agent

review the following information for setting up and configuring the devicehub agent driver set up the devicehub agent see docid\ d5z1sfjcvhqofidqmgu0c to review how to set up and configure the devicehub agent driver devicehub agent driver settings in litmus edge if you review or edit the settings of the osi agent device, refer to the following parameters parameter value type opc ua driver devicehub agent network address if unsure, leave the default value of 0 0 0 0 network port 41250 data validity period 60 if you docid 8se7z3pmrfwl1nmzcwalx in litmus edge, refer to the following supported data types and tag parameters there isn't a list of available register names supported data types word strarg null single byte reftonull mask arrayofdouble arrayofstring reftoempty reftosmallint reftomask smallint shortint reftodate reftodispatch date dispatch arrayofnull arrayofboolean reftovariant reftostring longword arrayofinteger arrayofdispatch error arrayofunknown arrayoflongword arrayofany string any arrayofolestring reftosingle reftounknown double olestring reftoolestring unknown arrayofint64 arrayofmask reftointeger currency variant arrayofsmallint arrayofvariant arrayofshortint arrayofword empty arrayofempty arrayofstrarg reftobyte integer boolean arrayofdate reftoerror reftoboolean arrayofsingle arrayofcurrency arrayoferror reftodouble reftocurrency unknowntype int64 arrayofbyte tag parameters name enter the case sensitive register name exactly as it is defined in the plc value type select a data type from the drop down list polling interval enter a value in seconds this determines how often the tag should poll the register for data 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 only publish nats messages when the value parameter changes to a new value 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 metadata 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)
