How to read data:
The identification, status and alarms tables should be read completely (this means the number of word to
read is equal to the table length).
The measurements table could be read word by word or per group, without exceed the length of the table.
(from 0x1060 to 0x108F).

from all units or modules are managed in order to create a ‘virtual single unit’. The logic combination ‘OR’ is
used to create the single unit data base, except following states and alarms :
