Introduction
The Control Expert DTM provides diagnostics information that is collected at configured polling intervals. Use this information to diagnose the operation of the embedded Ethernet scanner service in the CPU.
Connect the DTM
Before you can open the diagnostics page, make the connection between the DTM for the CPU’s embedded scanner service:

Diagnostics Information
The diagnostics window has two distinct areas:
left pane: LED icons indicate the operating status of modules, devices, and connections.
right pane: These pages show diagnostics data for these items:
CPU’s embedded scanner service
local slave nodes that are activated for the CPU’s embedded scanner service
EtherNet/IP connections between the CPU’s embedded scanner service and a remote EtherNet/IP device
When the appropriate DTM is connected to the CPU, Control Expert sends an explicit message request once per second to detect the state of the CPU’s embedded scanner service and of all the remote devices and EtherNet/IP connections linked to the CPU.
Control Expert places one of these status icons over the module, device, or connection in the left pane of the window to indicate its current status:

Run state is indicated. |
The health bit for every EtherNet/IP connection and Modbus TCP request (to a remote device, sub-device, or module) is set to active (1). |
|
One of these states is indicated:
|
The health bit for at least one EtherNet/IP connection or Modbus TCP request (to a remote device, sub-device, or module) is set to inactive (0). |
