Primary DTM

Use the primary DTM to configure the IP address settings, which the primary DTM will use when communicating with the HART module.

The HART module is designed to receive its IP address settings from the FDR server in the CPU, so configure the DHCP Address Server settings in the primary DTM.

Accessing Module IP Address Properties

Follow these steps to access the Address Settings page for the HART analog I/O module, where you can input IP address settings:

Step

Action

1

In the DTM Browser, right-click the M580 CPU.

2

Select Open from the context menu.

Result: The primary DTM configuration window opens.

3

Use the tree control on the left side of the DTM configuration window to navigate to a HART analog I/O module that you previously added to the configuration:

4

Select the Address Setting tab to access the IP address configuration settings:

5

Use the following fields to configure IP address settings for the selected HART analog I/O module:

IP Address

Enter the IP address that the FDR server in the CPU serves to the selected HART analog I/O 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 analog I/O module.

NOTE: Refer to the following topic: Creating a Device Name for DHCP.

6

Click Apply.

7

In the CPU primary DTM, select Channel Properties in the navigation tree.

8

Confirm that the Source IP Address is correct.

NOTE: Control Expert uses this IP address to communicate with the CPU.

Creating a Device Name for DHCP

When the DHCP client service is enabled in the primary DTM, the HART analog I/O module uses the Device Name identifier to request an IP address from the FDR server in the CPU. 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 Rack ID and Slot Number values, confirm that the values you input 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:

  • Mx80: a main local rack

  • M58A: primary rack in a Hot Standby network design

  • M58B: standby rack in a Hot Standby network design

  • 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 :

  • the string AHI0812 for the BMEAHI0812(H) module

  • the string AHO0412 for the BMEAHO0412(C) module

Sample device name identifiers could be:

  • Mx80_02_AHI0812 for a BMEAHI0812(H) module located at slot 2 of a main rack.

  • M58A_03_AHI0812 for a BMEAHI0812(H) module located at slot 3 of a primary Hot Standby rack

  • M58B_04_AHO0412 for a BMEAHO0412(C) module located at slot 4 of a standby Hot Standby rack

  • C001_05_AHO0412 for a BMEAHO0412(C) module located at rack 1, slot 5 of a remote I/O rack
