Using the Diagnostic Window

Introduction

Use the Diagnostic window to display:

LED icons (in the left pane of the window) that indicate the operating status of modules, devices and connections
pages (in the right pane of the window) that present diagnostic data for the following:
- the communication module
- local slave nodes activated for the communication module
- EtherNet/IP connections between the communication module and a remote EtherNet/IP device

NOTE: Before you can open the Diagnostic window, connect the DTM for the target communication module to the physical module itself. To do this, select the module node in the DTM Browser, then select Edit → Connect.

The Diagnostic window looks like this:

To open the Diagnostic window:

Diagnostic LED Icons

During the time that a communication module DTM is connected to the physical communication module, Control Expert sends an explicit message request once per second to detect the state of the communication module and the states of the remote devices and EtherNet/IP connections linked to that module.

Control Expert places one of the following status icons over the module, device or connection nodes in the left pane of the Diagnostic window to indicate its current status:

This icon...	Indicates the following state for a...
This icon...	Communication module	Connection to a remote device

	One of the following: unknown started stopped not connected	The health bit for at least one EtherNet/IP connection or Modbus TCP request, to a remote device or to a sub-device or module, is set to inactive (0).
