Verify Rmc-Xio Connection (Physical Connection) - ABB XIO-08 User Manual

–
Connectivity failure after an initially successful connection results from a change of connection status
The XIO Interface Overview screen displays information about the last successful communication
polls in addition to the red indicator for connection loss.

Verify RMC-XIO connection (physical connection)

Depending on the connection scenario, the XIO may connect to the field network switch (star topology),
to the RMC, or to another XIO (daisy chain). Loss of physical connection is detected and displayed on the
XIO Interface Overview screen. This procedure verifies if the RMC has successfully established a
connection with the XIO. Verify connection status from the Setup tab or from the Statistics tab. The
connection health parameters are displayed on both screens. This procedure describes how to check
connection status on the Setup screen.
To verify that the RMC-XIO link is established:
On the navigation tree, expand the XIO interface and select Communications.
b. Select the Setup tab
c. Verify Communication Status displays: No Error, for both reads and writes.
d. Verify that the Poll State displays: Active, for reads. Note that the Poll State for writes may
display: Inactive, during initial configuration. This does not indicate connection failure. An
Inactive state indicates that RMC applications have not sent writes to the XIO yet. Reads are
sent periodically. Writes are sent based on the applications and their programming.
e. Verify that the Port Status is Opened for both reads and writes.
