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 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:** 1. Note down the following information and refer to it when needed. 2. **Device**: Allen-Bradley 3. **Communication I/F**: Ethernet. Refer to the following figure. ::Image[]{src="https://api.archbee.com/api/optimize/SSUUxKZUk9bFTEPNn_6Zo/WCDrI7sm2UjoP1nUjVkY3_ab-micro850.png" size="80" width="604" height="345" position="center" darkWidth="604" darkHeight="345" showCaption="false"} 4. Launch RSLinx Classic, and connect the device to a PC using USB cable. The device is added to the browser. 5. Right-click the device and then click **Module Configuration**. ::Image[]{src="https://api.archbee.com/api/optimize/SSUUxKZUk9bFTEPNn_6Zo/PAvXurV3Acmsjt3gZGH8j_ab-micro850-browse482x338.png" size="80" width="482" height="338" caption="Module Configuration option" position="center" darkWidth="482" darkHeight="338" showCaption="true"} 6. From *Port Configuration*, set up the device Ethernet parameters. ::Image[]{src="https://api.archbee.com/api/optimize/SSUUxKZUk9bFTEPNn_6Zo/Sib9aU1z13qakcOoSP_lK_ab-micro850-ethernet-parameters.png" size="60" width="276" height="367" caption="AB Micro850 parameters" position="center" darkWidth="276" darkHeight="367" showCaption="true"} 7. 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**. ::Image[]{src="https://api.archbee.com/api/optimize/SSUUxKZUk9bFTEPNn_6Zo/3TbiMQQ5ZH9y7I1kigRxR_ab-micro850-adapter.png" size="70" width="382" height="294" caption="Configure Driver dialog box" position="center" darkWidth="382" darkHeight="294" showCaption="true"} 8. Launch CCS, Connected Component Workbench. 9. Click the **Discover **icon to browse the device. ::Image[]{src="https://api.archbee.com/api/optimize/SSUUxKZUk9bFTEPNn_6Zo/hDE__igxxrA_kWyUZcwel_ab-micro850-ccs-browse.png" size="80" width="418" height="426" caption="Connection Browser dialog box" position="center" darkWidth="418" darkHeight="426" showCaption="true"} 10. Double-click the device. ::Image[]{src="https://api.archbee.com/api/optimize/SSUUxKZUk9bFTEPNn_6Zo/DeTwluyUmHzpgdVBFTwO-_ab-micro850-details.png" size="80" width="880" height="573" caption="AB Micro850 details" position="center" darkWidth="880" darkHeight="573" showCaption="true"} # 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. | 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](docId\:Wpe2HMXelARLBnhWbuChY) to the connected device, refer to the following tag parameters and available value types. Refer to the following additional resources: - [Organize Device and Tag by Using Metadata](docId\:kR5ZcBhkXWK89Qti0v1t8) - [Tag Formula Variables](docId:9m6xLAQ9IoPW5alpru96S) ## 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.
