AB CompactLogix FreeTag (Gen1)

review the following information for setting up and configuring the ab compactlogix freetag (gen1) driver manufacturing connect edge compatible series compatibility parameter compatible items driver type serial validated devices/series compactlogix when configuring tags for this driver, you must enter the case sensitive register name exactly as it is defined in the plc see the free tags section below to learn more to set up and configure this device in manufacturing connect edge, you will need to do the following step 1 set up and configure the plc device step 2 set up the plc device in manufacturing connect edge devicehub step 3 configure the list of registers step 1 set up and configure the plc device record the serial communication parameters for the device otherwise, use plc software on your computer to look up these parameters these parameters will be used for setting up the driver in the next step step 2 set up the plc device in manufacturing connect edge devicehub configure the following parameters when you connect a device docid\ rfvijdxz7dbad8mwbisma with this driver update default values to the specific set up of your device parameter value type allen bradley driver ab compactlogix freetag (gen1) communication port local serial connection file path data bits 8 baud rate 19200 parity even, odd, none stop bits 1 slot 0 step 3 configure the list of registers when you add tags docid\ ioanzd2awqnkuppgee3eh to the connected device, refer to the following tag parameters and available value types refer to the following additional resources organize device and tag data by using metadata docid\ f b720nivllber44rfyhn tag formula variables docid\ pwd 7p kzjxkt pyawaow free tags this driver doesn't have a list of available register names in the devicehub add tag form to add tags, you must enter the case sensitive register name exactly as it is defined in the plc a connected status for the device won't display until a tag with a correct register name is created available value types bool sint int dint real lint 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 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)
