To set up and configure this device in Belden Horizon Data Operations, you will need to do the following:
- Step 1: Set up and Configure the PLC Device
- Step 2: Set up the PLC Device in Belden Horizon Data Operations 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 Belden Horizon Data Operations DeviceHub
Configure the following parameters when you [Connect a Device](docId\:T-cWPe0_Jsfw5-aoj8WPP) with this driver. Update default values to the specific setup of your device.

## Register Table
:::hint{type="info"}
**Note**: The address format in this Gen 2 driver is different from the replaced Gen 1 drivers for the same device.
:::
| **Name** | **Value Types** | **Address Format** | **Min Address** | **Max Address** | **Description** |
| -------- | --------------- | ------------------ | --------------- | --------------- | --------------- |
| X | bit | HHH | 0 | 2047 | Input Relay |
| Y | bit | HHH | 0 | 2047 | Output Relay |
| M | bit | DDDD | 0 | 2047 | Internal Relay |
| B | bit | HHH | 0 | 1023 | Link Relay |
| F | bit | DDDD | 0 | 1023 | Annunciator |
| R | word | DDDDD | 0 | 65535 | File Register |
| W | word | HHH | 0 | 1023 | Link Register |
| D | word | DDDD | 0 | 1023 | Data Register |
| CV | word | DDDD | 0 | 4095 | Counter Memory |
| TV | word | DDD | 0 | 255 | Timer Memory |
## 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.
- **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. 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
- log
- exp
- **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.
