− 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
When the IP destination address of UDP datagram, in which serial SCADA message re-
ceived from COM1(2) is encapsulated, is created, this Base IP is taken as the basis and
only the part defined by Mask is replaced by 'Protocol address'.
•
Mask
Default = 255.255.255.0
A part of Base IP address defined by this Mask is replaced by 'Protocol address'. The
SCADA protocol address is typically 1 Byte, so Mask 255.255.255.0 is most frequently
used.
•
UDP port (Interface)
List box: COM1,COM2, TS1-TS5, TCPM1, Manual.
This UDP port is used as the destination UDP port in UDP datagram in which serial
SCADA packet received from COM1(2) is encapsulated. Default UDP ports for COM1,
COM2 or Terminal servers 1-5 (TS1-TS5) or Modbus TCP (TCPM1) can be used or UDP
port can be set manually. If the destination IP address belongs to a RipEX and the UDP
port is not assigned to COM1(2) or to a Terminal server or to any special daemon running
in the destination RipEX, the packet is discarded.

Table
The Address translation is defined in a table. There are no limitations such as when the Mask
translation is used. If there are more SCADA units on RS485 interface, their “Protocol ad-
dresses” should be translated to the same IP address and UDP port pair, where the multiple
SCADA units are connected. There are 3 possibilities how to fill in the line in the table:
− One "Protocol address" to one "IP address" (e.g.: 56 −−> 192.168.20.20)
− Interval of "Protocol addresses" to one "IP address" (e.g.: 56-62 −−> 192.168.20.20)
− Interval of "Protocol addresses" to interval of "IP addresses" (e.g.: 56-62 −−> 192.168.20.20-
26). It is possible to write only the start IP and dash, the system will add the end address itself.
•
Protocol address
This is the address which is used by SCADA protocol. It may be set either in Hexadecimal
or Decimal format according the List box value.
Protocol address length can be only 1 Byte.
•
IP
IP address to which Protocol address will be translated. This IP address is used as des-
tination IP address in UDP datagram in which serial SCADA packet received from COM1(2)
is encapsulated.
•
UDP port (Interface)
This is UDP port number which is used as destination UDP port in UDP datagram in
which the serial SCADA message, received from COM1(2), is encapsulated.
•
Note
You may add a note to each address up to 16 characters long for your convenience. (E.g.
“Remote unit #1 etc.).
•
Active
You may tick/un-tick each translation line in order to make it active/not active.
•
Modify
Edit Delete Add buttons allow to edit or to add or to delete a line. The lines can be sorted
using up and down arrows.
•
Slave
SCADA Slave typically only responds to Master requests, however in some SCADA protocols it
can communicate spontaneously.
