Status byte [Non EIS; 8 bit coded]:
Each EIB Delta-Meter has a 1 byte
output communication object “Status byte” which can send the various status
information of the meter via the ABB i-bus
®
EIB. Each individual bit of the
1 byte telegram corresponds to a specific meter state or error type. Whenever
a new error is detected, the corresponding bit is set and the status byte is sent
on the bus (if selected). The sending behaviour of this object is defined in the
“Status” parameter window. The following applies for all the bits:
Bit value
“1”: Error
“0”: No error
The following table represents the connection between the individual bits, the
error type and the error codes in the meter.

The status byte key table in section 4.8 enables the transmitted status byte
value to be quickly converted to the individual error types.
During the initial configuration of the application software “Active energy
meter/1.1”, “Tariff meter/1.1” and “Combination meter/1.1”, the parameter
options are pre-programmed with a specific basic setting (in general, they
are set to inactive or disabled).
To avoid a high bus load, it is important to only activate functions and
parameters that are actually required. When selecting cyclic times or setting
the sending behaviour dependent on variable measured values, the resulting
bus traffic must also be taken into consideration to avoid communication
problems.
The reaction of the EIB Delta-Meter to a Reset or the restoration of the bus
voltage is dependent on the application software used and the parameter
settings. This is described in detail in the respective sections concerning the
communication objects, the parameter options and the parameter windows.
