About us
Overview
Control Expert incorporates the Field Device Tool (FDT)/Device Type Manager (DTM) approach to integrate distributed devices with your process control application.
For details, refer to chapter FDT Container.
Procedure
To access the DTM configuration for the BMECXM module in the Control Expert DTM Browser, follow these steps:
Step
Action
1
Click Tools → DTM Browser to open the DTM Browser .
2
In the DTM Browser, double-click the name that you assigned to the BMECXM module.
Result: The DTM Configuration window is displayed.
3
In the Configuration window, select:
DTM Connections
To connect or disconnect a DTM and the BMECXM module in the DTM Browser, follow these steps:
Step
Action
1
Select the DTM that you want to connect to or disconnect from.
2
Right-click and select:
  • Connect(1) to monitor and diagnose the real-time operation of the device, or
  • Disconnect(1)
NOTE: A connected DTM appears in bold text. The Connect command is available only for disconnected DTMs.
(1) You can also access the Connect and Disconnect commands in the Control Expert Edit menu.
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.
In the DTM Browser, two kinds of DTMs are instantiated automatically:
DTM Names
Each DTM has a default name when it is inserted into the browser. The name is limited to 26 characters.
This table describes the components of the default 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. For example: EtherNet/IP
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
DTM name
The default name is determined by the vendor. You can edit the name in the DTM Browser by clicking the DTM node or in the Ethernet Configuration tab of the CANopen master module screen.
NOTE: The DTM name is different from the Device Name that is used to get the IP address of the BMECXM0100 module in the IP/DHCP tab.
The default name for gateway and device DTMs is in the format <BusName><BusNumber>_d<DropNumber>_r<RackNumber>_s<SlotNumber>_<PartNumber>_[SubSetName]. The name of the subset is optional.
As an example on a local rack, a BMECXM0100 module on PLC bus, drop 0, rack 0, and slot 2, has this name: PLC0_d0_r0_s2_ECXM0100.
As an example on a remote drop, a BMECXM0100 module on EIO bus, drop 3, rack 1, and slot 4, has this name: EIO2_d3_r1_s4_ECXM0100.
DTM Status
The DTM Browser contains graphics to indicate the status of each DTM in the connectivity tree:
Status
Description
Built / Not-built
A blue check mark is superimposed on a device icon to indicate that the node/subnode is not built. This means that some property of the node has changed. Information stored in the physical device is thus no longer consistent with the local project.
Connected /
Disconnected
A connected DTM appears in bold text.
  • 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.
Ethernet ready
A is superimposed on a device icon to indicate that the device is an Ethernet ready equipment. This means that the equipment provides additional services compared to standard EIP or Modbus equipment. For more information, refer to Ethernet Ready Equipment.
