Approximately 6 seconds after a reset or bus voltage recovery, the actual
status of the communication object “Switch tariff” is queried via the bus.
Once a response has been received, a corresponding tariff change is carried
out and the current data and total of all the tariffs is sent on the bus.
However, if there is no response after approximately a further 4 seconds, the
meter switches to the last selected tariff (prior to the reset or bus voltage
failure) and the data is sent.To guarantee this function the ‘update flag’ of the
“switch tariff” communication object must be set to active (default setting).
The tariff control signal from the electricity supply company can be sent on
the EIB by connecting a tariff decoder unit to a binary input via potential free
contacts (1 per tariff). The required 8 bit value for switching the tariffs can be
generated using a binary input Serie ET/S 6.xxx.x together with the
applikation software “Value Edge Cyclic/3”.
Acknowledgement “Meter reading received”
[EIS 1; switching]
: If the
function “Active acknowledgement “Meter reading received”” is activated, the
EIB Delta-Meter expects an acknowledgement from the receiving EIB
devices after each transmission of a meter reading. This confirms that the
data has reached the recipient. If no acknowledgement is received after
approx. 2 seconds after the meter reading has been sent, the transmission is
repeated.The 1 bit input communication object is only visible if the
parameter “Active acknowledgement “Meter reading received”” in the
parameter window “Meter readings” is activated.
Telegram value “1”: Meter reading received
“2”: No function
Communication fault
[EIS 1; switching]
: If the EIB Delta-Meter has not
received a telegram at the communication object “Acknowledgement “Meter
reading received”” after sending the meter reading twice (see above), a
telegram is sent from the 1 bit output communication object “Communication
fault” to signal that there is a transmission fault. If a subsequent transmission
of the meter reading is acknowledged correctly, this error message is
removed. The communication object is only visible if the parameter “Active
acknowledgement “Meter reading received”” in the parameter window “Meter
readings” is activated.
Telegram value “1”: Communication fault
“0”: No communication fault
Fault
[EIS 1; switching]
: The 1 bit output communication object “Fault”
sends the state of the EIB Delta-Meter via the ABB i-bus
®
EIB in the form of
a group error message. An error message can have several causes and can
be decoded with the help of the communication object “Status byte” or by
reading out the error codes in the meter (see section 3.7).The sending
behaviour of these objects is defined in the parameter window “Status”.
Telegram value “1”: Fault
“0”: No fault
Fault acknowledgement
[EIS 1; switching]
: The 1 bit input communication
object enables the EIB Delta-Meter to be reset after an error has occured
and is only visible if the parameter “Fault acknowledgement” in the parameter
window “Status” is activated.The error message is only reset after an
acknowledgement if all the errors have previously been rectified.
Telegram value “1”: Reset error message
“0”: No function
