About the Control Expert DTM Browser
Original instructions
Introduction to FDT/DTM
Control Expert incorporates the Field Device Tool (FDT) / Device Type Manager (DTM) approach to integrate distributed devices with your process control application. Control Expert includes an FDT container that interfaces with the DTMs of EtherNet/IP and Modbus TCP devices.
An EtherNet/IP device or Modbus TCP device is defined by a collection of properties in its DTM. For each device in your configuration, add the corresponding DTM to the Control Expert DTM Browser. From the DTM Browser you can open the device’s properties and configure the parameters presented by the DTM.
Device manufacturers may provide a DTM for each of its EtherNet/IP or Modbus TCP devices. However, if you use an EtherNet/IP or Modbus TCP device that has no DTM, configure the device with one of these methods:
NOTE: The DTM for a BMENOC0301/11 module is automatically added to the DTM Browser when the module is added to the PLC bus.
Automatic DTM Creation
In a Unity Pro 11.0 or later application, DTMs for some Ethernet communication modules and other pre-configured devices (see the following list) are created automatically when added to an Ethernet rack on the main local or main remote drops. A default DTM name is assigned in the DTM topology, but you may modify the name:
DTMs are automatically created when you add a BMENOC0301/11 Ethernet communication modules to an Ethernet rack.
Windows Compatibility
M580 DTMs are compatible with the following operating systems:
NOTE: Unity Pro 10.0 no longer supports Microsoft Windows XP.

USB port on the PC
Open the DTM Browser
View the configuration options for the BMENOC0301/11 Ethernet communications module in the Control Expert DTM Browser:
Step
Action
1
Open a Control Expert project that includes a BMENOC0301/11 module.
2
Open the Control Expert DTM Browser (Tools → DTM Browser).
3
In the DTM Browser, find the name that you assigned to the BMENOC0301/11 module.
4
Double-click the name of the BMENOC0301/11 to open the configuration window.
5
View the DTM configuration parameters for the Ethernet communications module in the open dialog:
DTM Types
The DTM Browser displays a hierarchical list of DTM nodes on a connectivity tree. The DTM nodes that appear in the list have been added to your Control Expert project. Each node represents an actual module or device in your Ethernet network.
There are two kinds of DTMs:
This list contains these node types:
DTM Type
Description
communication (master)
Communication DTMs appear under the root node (host PC).
A communication DTM can support gateway DTMs or device DTMs as children if their protocols are compatible.
gateway
A gateway DTM supports other gateway DTMs or device DTMs as children if their protocols are compatible.
device
A device DTM does not support any child DTMs.
Node Names
Each DTM node has a default name when it is inserted into the browser. The default name for gateway and device DTMs is in the format <protocol:address> device name. (For example, < EtherNet IP:192.168.20.3 > BMENOC0301_from_EDS.)
This table describes the components of the default node name:
Element
Description
channel
This is the name of the channel communication medium into which the device is plugged. This name is read from the DTM and is set by the device vendor.
Example: EtherNet/IP, Modbus
address
This is the bus address of the device that defines the connection point on its parent gateway network (for example, the device IP address).
device name
The default name is determined by the vendor in the device DTM, but the user can edit the name.
Node Status
The DTM Browser contains graphics to indicate the status of each DTM node in the connectivity tree:
Status
Description
Built / Not-built
A blue check mark is superimposed on a device icon to indicate that the node (or one of its sub-nodes) is not built. This means that some property of the node has changed, so the information stored in the physical device is no longer consistent with the local project.
Connected /
Disconnected
A connected DTM appears in bold text. An unconnected DTM appears in plain text.
NOTE:
  • Connecting a DTM to its physical device automatically connects all higher level parent nodes up to the root node.
  • Disconnecting a DTM from its physical device automatically disconnects all its lower level child nodes.
NOTE: Connecting or disconnecting a DTM to or from its device does not also connect or disconnect Control Expert to or from the device. DTMs can be connected/disconnected while Control Expert is either offline or online.
Installed /
Not-installed
A red X is superimposed on a device icon to indicate that the DTM for that device is not installed on the PC.
Handling Invalid Nodes
As indicated above, a red X superimposed on a node indicates the DTM for that node is not installed on the PC. To resolve this situation, right-click the node to open a pop-up menu with these commands:
Command
Description
Delete
Removes the selected node (and its sub-nodes) from the DTM Browser.
Properties
Open the Properties of ... dialog box to identify the name of the missing DTM.
NOTE: After you install the DTM, reopen the Control Expert application.
