Service Port Configuration
Original instructions
About us
Access the Service Port Tab
Double-click the 140CRA31908 adapter module in the Control Expert project to view 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 the 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 case, 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.
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
all Ethernet traffic for the module
ETH2
CPU: all INTERLINK port traffic
adapter modules: Ethernet traffic through the first port
ETH3
CPU: Ethernet traffic through the first port
adapter modules: Ethernet traffic through the second port
Online Behavior
The Service Port parameters are stored in the application, but you can reconfigure (change) the parameters in connected mode. The values that you reconfigure in connected mode are sent to the 140CRA31908 module on the X80 remote drop or the CPU with EIO scanner service 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.) A message appears when the module does not respond to the explicit messages.
Limitations
The SERVICE port on the CPU 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 equipment:
