Adding a BME AH• 0•12 HART Analog I/O Module to a Remote I/O Drop
Original instructions
About us
Introduction
You can add an Ethernet HART analog I/O module to a remote I/O drop. With an Ethernet backplane, you can use the extended Ethernet functionalities with a link to the associated HART DTM to configure the module.
Quantum high-end CPUs (140 CPU 6•• •• also support Ethernet backplanes (BME XBP •••• in the following network configurations:
These Ethernet backplanes function in the same manner as when they are used in an M580 system. The eX80 EIO adapter modules also function in the same manner (including configuration, diagnostics, and performance) as when they are used in an M580 system.
Adding a HART Module
Follow these steps to add a HART analog I/O module to a remote I/O drop in your Unity Pro (10.0 or later) application.
NOTE: Unity Pro is the former name of Control Expert for version 13.1 or earlier.
NOTE: You can add a HART module to the main remote rack only. Extended remote racks do not support Ethernet backplanes, so they are not compatible with HART modules.
Step
Action
1
In the Project Browser in your Control Expert application, double-click Local Bus (or right-click and select Open) to open the local rack.
2
Add a 140NOC78000 Ethernet communication module (or confirm that you already added one) to the local rack.
Result: The associated DTM loads automatically.
3
In the Project Browser, double-click EIO Bus (or right-click and select Open) to open the remote I/O drop(s).
4
In the EIO Bus window, double-click an empty slot in the respective drop (or right-click and select New Device) to add a HART module.
5
In the New Device window, expand Analog, select the desired HART module (or double-click the module), and click OK.
6
In the main menu, click Tools → DTM Browser to open the DTM browser.
7
In the DTM Browser, right-click the 140NOC78000 module and select Add.
8
In the Device column of the Add window, select either BME AHI 0812 or BME AHO 0412 for the respective HART DTM, and click Add DTM.
Result: The Properties of device window opens with the DTM Alias name:
  • BME_AHI_0812 (for the input module)
    – or–
  • BME_AHO_0412 (for the output module)
9
In the Properties of device window:
  • Accept the Alias name in the General tab or edit as necessary.
  • Accept the default values in the Protocol information tab or edit as necessary
  • Click OK.
Result: The HART DTM appears in the DTM Browser associated with the 140NOC78000 module.
Configuring a HART Module IP Address
Follow these steps to access the Address Settings window for the HART module, where you can input IP address settings:
Step
Action
1
In the DTM Browser, double click the 140NOC78000 module DTM. (You can also right-click the DTM, and select Open.)
2
In the DTM configuration window, expand the Device List, and double-click the DTM of the HART module that you added to a remote I/O drop. (You can also right-click the HART DTM and select Open.)
3
Click the Address Setting tab.
4
Use the following fields to configure IP address settings for the selected HART module.
IP Address
Enter the IP address that the FDR server in the 140NOC78000 module serves to the selected HART module.
Subnet Mask
Accept the default value.
Gateway
Accept the default value.
DHCP for this device
Select Enabled.
Identified by
Select Device Name.
Identifier
Enter the Device Name identifier for the selected HART module.
NOTE: Refer to the topic Creating a Device Name for DHCP later in this topic.
5
Click Apply.
6
In the 140NOC78000 module DTM, select Channel Properties and confirm that the Source IP Address is correct.
Creating a Device Name for DHCP
When the DHCP client service is enabled in the 140NOC78000 module DTM, the HART module uses the Device Name identifier to request an IP address from the FDR server in the 140NOC78000 module. Create the Device Name identifier by concatenating the Rack ID and Slot Number values to the Module Name, as follows:
Device Name = Rack ID_Slot Number_Module Name
NOTE: When inputting the Rack ID and Slot Number values, confirm that the values describe the actual module position in the rack.
The components of the concatenated Device Name include the following:
Parameter
Description
Rack ID
A 4-character field that identifies the rack used for the module:
  • Cxxx: CRA
    The next box displays the ID of the remote rack. The ID range is 0 to 159.
Slot Number
A field that identifies the position of the module in the rack.
Device Name
Use the following module names for the purpose of generating a Device Name:
  • AHI0812 for the BME AHI 0812 module
  • AHO0412 for the BME AHO 0412 module
Sample device name identifiers include:
Configuring HART Module Parameters
Follow these steps to configure a HART analog I/O module in a remote I/O drop in your Unity Pro (10.0 or later) application:
Step
Action
1
In the DTM Browser, double-click the HART DTM (or right-click and select Open).
Result: The BME_AH•_0•12 - fdtConfiguration window opens.
2
In the DTM window, modify the parameters:
  • Module Overview
  • Address Table
  • General Information
  • Host Communication Status
  • Instrument Status
  • Multiplexer Status
  • Process Data
  • Configuration
3
In the DTM window, click:
  • Apply to save and leave the window open.
    – or–
  • OK to save and close the window.

Make any other necessary changes to your application. Then, click Build → Rebuild All Project.
5
When the application build is complete, click PLC → Transfer Project to PLC.
6
In the DTM Browser, right-click the HART DTM and select Connect.
7
When the DTM is connected, right-click the HART DTM and select Device menu → Additional functions → Transfer to FDR Server.
HART Module Device DDT
When you add an Ethernet HART analog I/O module to an Ethernet remote I/O drop (with a BME CRA 312 •0 adapter module), a read-only variable associated with a DDT is created automatically. Refer to the Device DDT topics for the HART modules, both input and output.
