Access the Service Port Tab
Double-click these modules in the Control Expert rack view to access the Control Expert Service Port tab:
head module on the local rack (140CRP31200)
adapter module on the remote drop (140CRA31200 or BMXCRA31210)
The Service Port tab appears:

Service Port Parameters
These parameters are on the Control Expert Service Port tab:
Field |
Parameter |
Value |
Comment |
---|---|---|---|
Service Port |
Enabled |
— |
Enable port and edit port parameters. |
Disabled |
— |
Disable port parameters. |
|
Service Port Mode |
Access (default) |
— |
This mode supports Ethernet communications. |
Mirroring |
— |
In port mirroring mode, data traffic from one or more of the other ports is copied to this port. A connected tool can monitor and analyze port traffic. NOTE: In
this mode, the SERVICE port acts like a read-only
port. That is, you cannot access devices (ping, connection to Control Expert, etc.) through the SERVICE port.

On Line Behavior
The Service Port parameters are stored in the application, but you can reconfigure (change) the parameters in connected mode. Values that you reconfigure in connected mode are sent to the remote drop’s adapter module or 140CRP31200 head module in explicit messages. (The changed values are not stored, so a mismatch can exist between the parameters that are being used and those that are in the stored application.) If the module does not respond to the explicit messages, a message appears.
Limitations
The SERVICE port on the 140CRP31200 head module and the adapter modules have the same limitations as the cloud port of the dual-ring switch (DRS). Therefore, the module's cloud port and the DRS's cloud port can be connected to the same equipment.
The maximum load the module can process from distributed I/O devices:
5 Mbps: per SERVICE port
20 Mbps: total distributed I/O traffic on the main ring
For more information about considerations that apply to the use of the distributed I/O cloud port and the service port on the DRS, refer to the Predefined Configuration Files topic in the Quantum Ethernet I/O System Planning Guide.
