Note: There is no 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.
Broadcasting is not available with mobile GPRS/UMTS networks.
• First Slave Address
Default = 1
Slave addresses are not defined in the ITT Flygt protocol. However
Slave addresses have to be defined in the Unit 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, the 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 Unit does not
accept the next WAIT COMMAND (discards it), till the Wait timeout expires. 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.
More Modbus Masters can be used within one network and one Slave can be polled by more Masters.
Modbus protocol configuration uses all parameters described in
Common parameters .

Profibus
RipEX supports Profibus DP (Process Field Bus, Decentralized Periphery) the widest-spread version
of Profibus. The Profibus DP is supported even by M!DGE/MG102i, but it will work satisfactorily only
with mobile networks with very short transport delays, like LTE or UMTS. The Profibus protocol config-
uration uses all parameters described in Common parameters.
