EIB Delta-Meter
Electricity Meters
The sending behaviour of the communication objects "Meter reading" is
defined in the parameter window "Meter readings".
Do not send: If this setting is selected, the EIB Delta-Meter does not
automatically send its meter reading on the bus. It is only possible to read
out the current meter readings by reading out the object values via
"Value_Read", e.g., using the EIB Tool Software ETS. The meter readings
are updated every 8 seconds.
Send cyclically: In this setting, the meter readings are sent cyclically via the
®
ABB i-bus EIB. The sending interval (tolerance ±1.5%) is defined with the
parameter "Period". If several meters have the same cyclic time, they can
send with a time delay T
cation problems.
Send on request: This setting enables the current meter readings to be
actively read out using the communication object "Request meter reading".
Once a request telegram with the value "1" has been received, the meter
reading is stored and sent after the transmission delay T
®
the ABB i-bus EIB. The transmission delay T
being sent simultaneously if several meters react to the same meter reading
request telegram.
Active acknowledgement "Meter reading received": With the settings
"Send cyclically" and "Send on request", the user can choose to send with or
without a receipt confirmation. If "yes" is selected, the EIB Delta-Meter
expects to receive an acknowledgement telegram via the communication
object "Acknowledgement "Meter reading received"" after each transmission
of a meter reading. If an acknowledgement is not received after approx.
2 seconds, the meter reading is sent again. If the second repetition is not
acknowledged, an error message is sent via the communication object
"Communication fault". During this period, the stored meter readings are
maintained. They are only updated once a transmission has been
acknowledged or a communication fault has been reported.
