Node Address Settings and I/O Allocation Section 2-2
Slice I/O Unit
Participating/Withdrawn
Flags These flags can be used to monitor the connection status (participating or
withdrawn) of the Slice I/O Units connected to the Communications Unit.
There are always 8 words allocated to the Participating/Withdrawn Flags (4
words for the Participating Flags and 4 words for the Withdrawn Flags),
regardless of the number of I/O Units that are connected.
These flags are not allocated in the Master by default. The flags must be allo-
cated with the Configurator.
These flags can be read with the Configurator or an explicit message com-
mand.
Note (1) Each bit corresponds to the unit number of a connected Slice I/O Unit.
(Up to 64 Units can be monitored.)
(2) Each Unit’s status can also be monitored with the TS indicator on the front
of the I/O Unit.
