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, follow the steps below.

Refer to the following parameters.

Communication mode: DF1 Full Duplex protocol 19200, None, 8, 1 (default)

To configure the PLC:

1. Note down the following information and use it as needed. Device: Allen Bradley Communication I/F: Ethernet. Refer to the following figures.

2. Connect the device to your PC with Serial Port 25-pin D-shell cable.

3. Launch RXLinx Classic, click the Configure driver icon, and add an RS232 DF1 device driver.

4. Configure the driver as follows, and then click Auto Configure.

5. Launch RSLogix 5 pro v8.00, and then click Comm > Who Active Go Online.

6. Find the device to be connected, and click Online.

7. Check communication settings in Channel Configuration. Use Channel 1.

8. Use Channel 3A to set up the IP Address.

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.

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. 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.

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:

sqrt

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 only publish NATS messages when the value parameter changes to a new value. 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. Metadata 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).
