Modbus TCP (Gen1)

note this driver will be deprecated in a future release we recommend using the gen 2 modbus tcp docid wku1najuga3kzu g9vty review the following information for setting up and configuring the modbus tcp (gen1) driver manufacturing connect edge compatible series compatibility parameter compatible items driver type ethernet when to use tcp connection to a modbus device replaced with gen 2 driver modbus tcp docid wku1najuga3kzu g9vty 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 if the device is configured for ethernet access, find its network parameters otherwise, follow the steps below to configure your device note down the following information and refer to it when needed device modbus tcp x20cp1381 communication i/f ethernet refer to the following figure launch automation studio v4 6 2 software, create a new project, and then select identify hardware configuration online click identify hardware to browse the device automatically 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 modbus driver modbus tcp (gen1) network address the device address you defined in step 1 port 502 station id 1 step 3 configure the list of registers when you add tags docid\ ioanzd2awqnkuppgee3eh 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\ f b720nivllber44rfyhn tag formula variables docid\ pwd 7p kzjxkt pyawaow register table name value type address format min address max address description d bit

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 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 address enter a tag address the value must in the decimal format, within the allowed min/max range omit the leading zeros the device might use the decimal (d), hexadecimal (h), or octal (o) address format see the register table at the bottom of the dialog box for bit tags, append the bit address without the bit separator the lowercase letters in the address format indicate how many digits you should enter in the bit address count enter the number of register values to read a count higher than 1 will generate an array of values from the address value configured and respective subsequent address values 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)
