At a Glance

The status of a DTM is indicated in the DTM Browser: Ready, Not-Built, Connected and Installed.

Ready

Ready devices or modules are devices or modules that are used by DTMs and fully integrated in the Control Expert software, they mainly bring two particularities:

• They use new Control Expert mechanisms to be integrated into the Control Expert hardware catalog.

• They are managed by Control Expert Ethernet I/O bus editors as for any X80 I/O modules.

A green “R” icon indicates that the device or module is a Ready one.

Built or Not-Built DTMs

Build status:

• Not-Built: A blue check marks indicated that a node or one of its sub-nodes have changed, the information stored in the physical device is no longer consistent with the local project.

• Built: After building the Control Expert project, the blue check mark is no longer in front of browser nodes that were changed before the build.

Connected or Non-Connected DTMs

Connecting a DTM to its physical device automatically connects all higher level parent nodes up to the root node (all DTMs that the DTM being connected depends on.

Disconnecting a DTM from its physical device automatically disconnects all its lower level child nodes (all DTMs that depend on the DTM being disconnected).

Connection status:

• Connected: Connected nodes are represented by bold text in the browser. A node can be connected without all its sub-nodes being connected.

• Non-Connected: Non-connected nodes are represented by normal text.

  NOTE: Connecting a fieldbus or device is not linked the Control Expert connection to a PLC (Off-line or On-line). DTMs can be connected/disconnected while Control Expert is either Off-line or On-line.

Installed DTMs

Installation status:

A red X on the icon of a DTM indicates that the DTM software is not installed on the PC.

• This status is updated (red X added) when devices are detected but no DTM software is installed on the Host PC when the user:

  • Updates the Hardware Catalog

  • Tries to build the application

  • Tries to use a service in one of the 2 right-click contextual menus in the DTM Browser

  • Tries to use the Open service by left-clicking twice on a DTM in the DTM Browser

• This status is updated (red X removed) when the user updates the Hardware Catalog with the missing DTM.

A right-click on an invalid or non-installed DTM opens a 2-item contextual menu:

Function	Description
Delete	This removes the selected DTM (and its sub-nodes) from the DTM project.
Properties	To help identify the non-installed DTMs, this function displays one tab (Device information) in the Properties of dialog box:
