Add Tags

you can add tags to connected devices by navigating to devicehub > tags to learn more about the list of registers for specific devices, visit the industrial systems connection guide docid\ q9scssqe xxk9dg9by8vr you can add tags as follows add a tag adds a single tag for the selected device multiple tags in a csv file uploads a list of tags from a csv file browse tags search for pre defined device tags and select the ones to add see search for pre defined device tags docid\ mocoh 5sebdz22wwbjsuf to learn more before you begin before creating tags, make sure you have connected a device refer to connect a device docid\ rfvijdxz7dbad8mwbisma important refer to the following information on free tags and opc ua drivers certain device drivers do not have a list of register names in the add tag form these are referred to as free tags you must enter case sensitive register names exactly how they are defined in the device devices do not display a connected status until a tag with a correct register name is created see devicehub troubleshooting docid\ tcrpco1f0sonhurjyekfv for more information for opc ua, map the opc server tags to the client enter the register name using this format where the semicolon is required ns=1;s=tagname for example ns=2;s=channel1 device1 tag1 add an individual tag you can add a tag for a single device register or upload tag details with a comma delimited csv file see the add multiple tags section for more information about loading comma delimited values to add a tag for a single register navigate to devicehub > tags from the tags pane, click the add tag icon, and then select add a tag the add tag dialog box appears for manufacturing connect edge version 3 5 6 and earlier, click add new tag , and then select add one click the select a device field, and then select an option from the drop down list only devices that had been added to manufacturing connect edge appear in the drop down list the fields displayed in the add tag dialog box depend on the device driver type from the add tag dialog box, complete the parameters for the tag refer to the industrial systems connection guide docid\ q9scssqe xxk9dg9by8vr for parameters specific to your device driver and review the tag parameters section the following optional parameters apply to all device drivers configure them as needed tag formula enter a formula for the tag to process the generated data see tag formula variables docid\ pwd 7p kzjxkt pyawaow to learn more two variables are permitted value (current tag value) and timestamp (current tag unix time in milliseconds) the following math functions are available sin cos tan sqrt 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 for additional functions on tag values such as rounding and data conversions, you can use analytics docid\ ijqp0ihd8tue3ntgltufp or the flows manager docid 5bbsox0doib rc iuliim 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 see organize device and tag data by using metadata docid\ f b720nivllber44rfyhn to learn more when done configuring the tag, click add tag the tag appears in the tags pane add multiple tags you can add multiple tags at once by downloading a csv template file, filling out the file with tag details and additional tag fields as needed, and then uploading the csv file important when saving the csv file, you must ensure that commas are used as column delimiters and not semicolons if semicolons are used as column delimiters, you won't be able to upload the csv file successfully see tag upload through csv issues docid\ cudhd8fpkve8pydnu8zrx to learn more step 1 download a sample csv template you will need to download a template csv file that has common device tag fields you may need to update the file with additional fields based on the device tags you're adding to download a sample csv template for manufacturing connect edge version 3 10 0 and later, select the appropriate device for earlier versions, click the help icon and select sample csv template click the help icon and select sample csv template step 2 populate the csv template file you can now populate the csv template with the tags that will be added a row/record for each tag must be populated with attribute values, as described below the order of the attribute columns in the template file may be in any order refer to the following sections for information on populating the csv template file example of a tag csv file https //archbee doc uploads s3 amazonaws com/ssuuxkzuk9bftepnn 6zo/mvxcayfa7 z637ipdawsv tag sample csv deviceid devicename drivername name tagname description valuetype registerid publishcov

error displays, but the tags will still be successfully added attribute values are required unless noted as optional if an optional value is null, it is ignored this allows for the loading of register definitions for multiple device types from a single file if the value is null and the device driver defines it as mandatory, the tag is not imported if an optional value is present in the csv file, but it is not supported by the device driver, it is treated as an error and the tag is not imported attribute columns in the csv can be in any order attribute name data type description required notes deviceid string id of the device you can get this value from the device tile in devicehub > devices no get this value from the copy icon next to the device id in the device tile in devicehub > devices if a device identified by the deviceid is not found, devicename is used devicename string the name you configure for the device yes drivername string driver name is for validating optional attributes

metadata key value pairs no pollinginterval float polling interval in seconds no how often the tag will poll the driver for a value 0 means auto polling disabled 1 means poll every 1 second if left blank, a value of 1 is set csv formatting and escaping rules because csv format is not standardized, several different methods could be used for escaping special characters and, depending on locality, a different value separator may be used for example, in european countries, a semi colon is widely used as a separator the manufacturing connect edge csv specification adheres to the rules used by microsoft excel, as listed below field separators can be comma ( , ), semicolon ( ; ), or tab ( \t ) fields can have white spaces around them this space is removed during processing fields can be escaped with double quotes ( " ) or single quotes ( ' ) leading or trailing white spaces inside the quotes are preserved any separator characters within a quoted field is treated as part of the field value any quotation character in a field value must be escaped with a backslash ( \ ) character fields are parsed based on their data type string values are read "as is" and numeric values are parsed with a numeric parser empty fields are treated as null values step 3 upload populated csv file of tags once the csv template file is populated, you can upload it to add all tags that were added to the file to upload a populated csv file for manufacturing connect edge version 3 10 0 and later, navigate to the tags pane, and then select the appropriate device for earlier versions, click the help icon and select upload csv , and then continue with step 3 click the add tag icon and select upload csv click select csv select the file to upload and click open from the upload tags dialog box, click upload upon a successful upload, the tags appear in the tags pane if the details in the csv file do not match the expected configuration, error messages indicate the issues search for pre defined device tags some devicehub devices give you the option of searching, selecting, and downloading pre defined device tags devices that support searching for device tags display a tag icon in the bottom right corner of the device card there are two ways to search for device tags note the server search option is available for manufacturing connect edge version 3 5 2 and later use browse tags docid\ vddnslvnu mnguwwiessp to view all available tags for a device you can then select and download tags applicable for your devicehub device use server search docid\ dggn ulr8mf3yt1zki8lx to search for device tags you will need to know the name of the tags you want to search for and add to your devicehub device
