AC460 Subsystem Status Display
PROFIBUS Interface
The status of the PROFIBUS Interface will show if it is active, failed or missing. In
addition, you can select the PROFIBUS LAN display by selecting its display target.
TRIO Interface
The status of the TRIO LAN submodule will show if it is active, failed or missing.
Select the TRIO Lan display by selecting its display target.
S800 I/O Interface
The status of the S800 I/O Interface submodule will show if it is active, failed or
missing. In addition, you can select the
selecting its display target.
MVI Interface
MVI (Multi Vendor Interface) is redundant at the port level for PLC I/O. MVI
redundancy is determined by the controlling application (client) program.
Redundant ports may reside on the same, or on a different MVI submodule.
Therefore, no MVI submodule is considered to be a "backup" for another. The
status of the MVI submodule will show if it is active, failed or missing.
DCN Interface
The DCN interface is similar to the TRIO interface, in that both are considered to be
active simultaneously, with no preference for either one as primary.
TC520 Monitor Status
The TC520 Status Module information includes the power supply status, fan status
and user-defined auxiliary status inputs (available from the front panel of the TC520
status monitor). The status can be either DOWN (red) or ACTIVE (green) for all the
TC520 functions. If the TC520 monitor status is DOWN, then the status for all the
other TC520 functions will be UNKNOWN (yellow). The rectangles for the user-
defined auxiliary status inputs (A1, A2, B1, B2) are colored green when active, and
colored red when inactive.
