Note
Content
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withdrawn) of the Slice I/O Units connected to the Communications Unit.
There are always 8 words allocated to the Participating/Withdrawn Flags (4
words for the Participating Flags and 4 words for the Withdrawn Flags),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.

(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.
Description

Monitors the network power supply voltage using the voltage
threshold set with the network power supply voltage monitor
function.
Monitors the Unit's operating time the power ON time thresh-
old set with the Unit power ON time monitor function.
Indicates whether or not the automatic parameter restoration
to the Slice I/O Units was completed properly. This flag will be
ON if the restore operation failed and OFF if data was restored
properly to all Units.
This is the overall Unit status flag. This flag will be ON if any
one of the other flags (bits 0 to 13) is ON.
Indicates whether I/O data is being exchanged normally.
Description
ON: Participating (properly allocated to Master)
OFF: Not participating (An I/O Unit will not join communica-
tions if the registered table is enabled and a verification error
occurred with the Unit.)
ON: Communications error occurred or the Unit was with-
drawn after participating in communications.
OFF: Never joined communications or participating normally.
