Service Port Configuration

Access the Service Port Tab

The BM•CRA31210 adapter modules have a service port that can be configured for Ethernet communications or for port mirroring.

Double-click the adapter module in the Control Expert configuration to access the Service Port tab.

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.
Service Port	Disabled	—	Disable port parameters.
Service Port Mode	Access (default)	—	This mode supports Ethernet communications.
Service Port Mode	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. NOTE: This mode is not available on the BMXCRA31200.
Access Port Configuration	Service Port Number	ETH1	You cannot edit the value in the Service Port Number field.
Port Mirroring Configuration	Source Port(s)	Internal Port	Ethernet traffic through the internal port
		ETH2	Ethernet traffic through the first RIO port
		ETH3	Ethernet traffic through the second RIO port
		Backplane Port	Ethernet traffic through the backplane port

Online Behavior

The Service Port parameters are stored in the application, however you can reconfigure (change) the parameters in the connected mode. Values that you reconfigure in the connected mode are sent to the remote drop adapter module or the CPU module in explicit messages. If the module does not respond to the explicit messages, a message appears.

NOTE: 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.

NOTE: The Service Port configuration can be read and modified online using the Service Port Control Object CIP object.
