review the following information for setting up and configuring the ab logix serial driver manufacturing connect edge compatible series compatibility parameter compatible items driver type serial validated devices/series compactlogix, controllogix, flexlogix, micro800 replaces gen 1 driver(s) ab flex serial (gen1), ab compactlogix freetag (gen1), ab controllogix freetag (gen1), ab micro850 freetag (gen1) 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 ensure the plc device is configured for serial communication note the serial port configuration parameters including baud rate, data bits, stop bits, and parity settings identify the local serial port (for example, /dev/ttys0 ) on your manufacturing connect edge gateway that will connect to the plc ensure proper physical connectivity between the plc's serial port and the gateway's serial port step 2 set up the plc device in manufacturing connect edge devicehub configure the following parameters when you connect a device docid\ nm1lqfefya dsiffitity with this driver update default values to the specific setup of your device parameter value type allen bradley driver ab logix serial plc type select the appropriate plc type (compactlogix, controllogix, flexlogix, or micro 800) device file the local serial connection file path, for example /dev/ttys0 baud rate update to match your device configuration the default is 19200 data bits 8 stop bits 1 parity none step 3 configure the list of registers when you add tags docid\ h5heqicxrcy3nch9kbg9i to the connected device, refer to the following register table and tag parameters refer to the following additional resources organize device and tag data by using metadata docid\ jouzsq77y8z4dt jdgct tag formula variables docid 4yhyz92z7ggpgswqp05tf register table name value types access type description r bool, sint, int, dint, lint, byte, uint, udint, ulint, real, lreal, string r/w read/write tags to plc tag parameters name select a register name from the drop down list the available options depend on the names in the register table value type select a data type from the drop down list the available options depend on the register name selected and include bool, sint, int, dint, lint, byte, uint, udint, ulint, real, lreal, and string 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 this should match the tag name configured in your plc program 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 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)
