There is not a possibility to set the Broadcast address, since ITT Flygt broadcast messages
always have the address 0xFFFF. Hence when the Broadcast is On, packets with this
destination are handled as broadcasts.
First Slave Address
Default = 1
Slave addresses are not defined in the ITT Flygt protocol. However Slave addresses
have to be defined in the RipEX network. This is the First Slave address in decimal format.
Number of Slaves
Default = 1
Since the ITT Flygt protocol Master (centre) polls the Slaves (remotes) one by one without
any addressing, number of slaves has to be defined.

Wait timeout [ms]
Default = 5000
An ITT Flygt Slave sometimes sends the WAIT COMMAND (0x13) to its Master. The
RipEX does not accept the next WAIT COMMAND (discards it), till the Wait timeout does
not expire. The Recommended value is in the 1-10 seconds range.
■ Modbus
Modbus RTU is a serial polling-type communication protocol used by Master-Slave application.
When RipEX radio network run in Router mode, more Modbus Masters can be used within one
Radio network and one Slave can be polled by more Masters.
Modbus protocol configuration uses all parameters described in Common parameters.

Advanced parameters, Slave
Retries [No]
Default = 0 (min. 0, max. 7)
When an original frame is received from the Radio channel, it is transmitted to the connected
device and waits for an acknowledgement. Any incoming frame from the device is treated
as an acknowledgement. If there is no acknowledgement (no incoming frame), the original
frame is re-transmitted to the connected device. The Retries parameter controls how many
times the frame is re-transmitted when not acknowledged.
