Diagnostics via the M580 CPU DTM

The M580 CPU DTM provides the following diagnostic services:

  • Device discovery

  • CIP Safety I/O device health

CIP Safety Device Discovery

When Control Expert is operating online, you can use its field bus discovery service to discover first level CIP Safety devices – i.e. devices that are connected directly to the CPU – in your network. Only devices with a DTM that matches a DTM that is registered in the host PC DTM Catalog are discoverable.

Device discovery is performed by right-clicking the CPU DTM (BMEP58_ECPU_EXT) in the DTM Browser, then selecting Field bus discovery to open a dialog of the same name, which displays discovered devices. You can use the tools of this dialog to add device DTMs to your project. The devices you add appear under the CPU in both the DTM Browser and in the navigation tree of CPU DTM.

For more information on how to use this service, refer to the Field Bus Discovery Service topic.

CIP Safety Device Connection Health

When Control Expert is operating online, the navigation tree of the CPU DTM displays an icon indicating the health of each connection for CIP Safety I/O devices that have been added to the project:

  • indicates the connection is in RUN state.

  • indicates the connection is in STOP state, or not connected, or unknown.
