6.6.2 eBus
Param & Display AZL eBus Address
SendCycleBU
For Bus communication, the interface has to be activated and the bus protocol has
to be defined.
eBus address
Parameter Address defines the eBus address, which is used to communicates
with the W-FM.
Send cycle
Parameter SendCycleBU defines the time for the send cycle. The W-FM trans-
mits its operating data to the eBus participants in the cycle set.
6.6.3 Modbus
Param & Display AZL Modbus
For Bus communication, the interface has to be activated and the bus protocol has
to be defined.
The display and operating unit (ABE) operates as Slave in the Modbus protocol.
The RTU-Modus is used for transfer.
Modbus address
Parameter Address determines the Modbus address of the display and operat-
ing unit (ABE).
Baud rate
Parameter Baudrate determines the transfer speed. The Baud rate of the dis-
play and operating unit (ABE) and the Modbus participant connected must be
identical.
Parity
Parameter Parity determines the type of parity protocols. The parity of the dis-
play and operating unit (ABE) and the Modbus participant connected must be
identical.
Time out
Parameter Timout determines how long after Modbus communication fails the
display and operating unit (ABE) switches from Remote to Local .
If building management is deactivated or the Modbus connection fails, the internal
load controller of the W-FM takes over the control and the internal setpoint (W1) is
activated. Prerequisite is that the W-FM is equipped with an internal load controller
and has been configured [ch.6.12].
