Island Bus State (Selector 04h)
The island bus state represents the main states of the island bus scanner, the
firmware that drives the island bus.
When the selector value is 04, the island bus state information is transmitted as the
status word’s low byte value:
Byte
Value
Meaning
00h The island is initializing.
40h The island bus has been set to pre-operational mode, for example, by the reset function in the
Advantys STB configuration software.
60h NIM is configuring or auto-configuring—Communication to all modules is reset.
61h NIM is configuring or auto-configuring—Checking the module ID.
62h The NIM is auto-addressing the island.
63h NIM is configuring or auto-configuring—Bootup is in progress.
64h The process image is being set up.
80h Initialization is complete, the island bus is configured, the configuration matches, and the island bus is
not started.
81h configuration mismatch—Non-mandatory or unexpected modules in the configuration do not match and
the island bus is not started.
82h configuration mismatch—At least one mandatory module does not match and the island bus is not
started.
83h serious configuration mismatch—The island bus is set to pre-operational mode and initialization is
aborted.
A0h The configuration matches and the island bus is operating.
A1h Island is operational with a configuration mismatch. At least one standard module does not match, but
all mandatory modules are present and operating.
A2h serious configuration mismatch—The island bus was started but is now in pre-operational mode
because of one or more mismatched mandatory module(s).
A4h* Nodes are individually set to operational through a Run network or Start heartbeat request.
A5h* Nodes are individually set to operational. The last missing mandatory module has been successfully
booted but there are missing optional or unexpected modules.
C0h Island has been set to pre-operational mode, for example, the stop function in the Advantys STB
configuration software.
*Transient state—When this segmented transmission is complete, the island bus is updated.
