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
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: Allen-Bradley
- Communication I/F: Ethernet. Refer to the following figure.

- Launch RSLinx Classic, and connect the device to a PC using USB cable. The device is added to the browser.
- Right-click the device and then click Module Configuration.

- From Port Configuration, set up the device Ethernet parameters.

- Create an AB_ETHP-1 driver. Select an adapter on the same subnet as the device. If you cannot find it in the local subnet, select Remote Subnet.

- Launch CCS, Connected Component Workbench.
- Click the Discover icon to browse the device.

- Double-click the device.

Step 2: Set up the PLC Device in Belden Horizon Data Operations DeviceHub
Configure the following parameters when you Connect a Device with this driver. Update default values to the specific setup of your device.
Parameter | Value |
|---|---|
Type | Allen-Bradley |
Driver | AB Micro850 (Gen1.3) |
Network address | The device address you defined in Step 1 |
Port | 44818 |
Slot Number | 0 |
Step 3: Configure the List of Registers
When you Add Tags to the connected device, refer to the following tag parameters and available value types.
Refer to the following additional resources:
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
- byte
- word
- dword
- lword
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
- 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.
