7.1.3.2. Common Protocol parameters
Each SCADA protocol used on serial interface is more or less unique. The COM port protocol module
performs conversion to standard UDP datagrams to travel across RipEX2 Radio network. The same
settings are valid for Terminal servers as well (for more details about TS see
Section 7.1.4, “Terminal
servers” ).
Protocol
List box {None; Transparent; Async Link; DNP3; DF1; IEC101; Mars-A; Modbus RTU; PR2000;
RDS; S3964R; SAIA S-BUS; UNI}, default = "None"
Transparent protocol can be used when unit operates in Bridge mode only. All the traffic is bridged
transparently to RipEX2 network.
Broadcast
List box {On; Off}, default = "On"
Some Master SCADA units sends broadcast messages to all Slave units. SCADA application typ-
ically uses a specific address for such messages. RipEX2 (Protocol module) converts such message
to a customized IP broadcast and broadcasts it to all RipEX2 units resp. to all SCADA units within
the network.
Broadcast address
Number {0 – 65535}, default = 255
The protocol address which is treated as broadcast address.
Address translation
List box {Mask; Table}, default = "Mask"
SCADA protocol address is translated to the IP address using either Mask (common rule for all
addresses) or Table (specific rule per address) type of conversion
Base IP / Mask
A part of Base IP address defined by this Mask is replaced by 'Protocol address'. The SCADA
protocol address is typically 1 byte long, so Mask 24 (255.255.255.0) is most frequently used. This
IP address is used as a destination IP address of the UDP datagram into which the serial SCADA
packet received from COM is encapsulated.
