System status

Status messages are sent for all items (crosspoints, virtual crosspoints, salvos and
parameters) when the status has changed.

::= 'x'

::=

|||

::= 'l'

::= 'vt'

::= 'sg'

::= 'pg'

6.1 Status messages

Whenever the state of a monitored item, i.e. crosspoints, parameters or signal presence, in
the system changes, status messages are sent to all listeners. A single state change may
generate any number of status messages, caused by the interconnection of parameters,
physical and virtual crosspoints and the use of salvos.

6.2 Request Crosspoint Status

— Entire Level

This command is used to requests the crosspoint status of all destinations on a specified
level. For compact and v128 modes, lock state and user ID are omitted, and the sl
command is defined.

::= 's' 'l'

::= [ {}]

::= 'x' [ ]

::= 'l'

::= 'sl' 'l' (v128 and compact modes only)

::= 'xl' (v128/compact
modes)
