The bit status tables (input registers) presents individual on/off event conditions for

elements) and related conditions, for example, detection zone alarms . In each
table, the value 1 indicates that the condition is present on the corresponding
object. The list of objects is defined at configuration time.
The table below collects the list of bit status tables.
