** - denotes items to be used only when either all or some RTUs (Remote Telemetry Unit) on remote
sites are connected via RS232 or RS485 interface to RipEX, using the Modbus RTU protocol. Then
automatic conversion between Modbus TCP and Modbus RTU protocols takes place for such units.
List box: On, Off
Default = Off
My TCP port
Default = 502
TCP port used for Modbus TCP in RipEX.
TCP Inactivity [s]
Default = 120
TCP socket in RipEX is kept active after the receipt of data for the set number of seconds.
Broadcast**
List box: On, Off
Default = Off
Some Master SCADA units send broadcast messages to all Slave units. SCADA application
typically uses a specific address for such messages. RipEX (Protocol utility) converts such
message to an IP broadcast and broadcasts it to all RipEX units resp. to all SCADA units within
the network.
If On, the address for broadcast packets in SCADA protocol has to be defined:
Broadcast address format
- List box Hex, Dec - format in which broadcast address is
defined.
Broadcast address
- address in the defined format (Hex, Dec)
Address translation
List box: Table, Mask
Default = Mask
In a SCADA protocol, each SCADA unit has a unique address, a "Protocol address". In RipEX
Radio network, each SCADA unit is represented by an IP address (typically that of ETH interface)
and a UDP port (that of the protocol daemon or the COM port server to which the SCADA device
is connected via serial interface).
A translation between "Protocol address" and the IP address & UDP port pair has to be done.
It can be done either via Table or via Mask.
Each SCADA message received from serial interface is encapsulated into a UDP/IP datagram,
where destination IP address and destination UDP port are defined according the settings of
Address translation.
Mask
Translation using Mask is simpler to set, however it has some limitations:
− all IP addresses used have to be within the same network, which is defined by this Mask
− the same UDP port is used for all the SCADA units, which results in the following limitations:
− SCADA devices on all sites have to be connected to the same interface (COM1 or
COM2)
− only one SCADA device to one COM port can be connected, even if the RS485 interface
is used
Base IP
Default = IP address of ETH interface
