When the IP destination address of the UDP datagram, in which serial SCADA message
received 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.
Default = COM1
This UDP port is used as the destination UDP port in the 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 destin-
ation RipEX, the packet is discarded.
○
Table
The Address translation is defined in a table. There are no limitations like when the Mask
translation is used. If there are more SCADA units on RS485 interface, their “Protocol addresses”
translate to the same IP address and UDP port pair.
There are 3 possibilities how to fill in aline in the table:
1. One "Protocol address" to one "IP address" (e.g.: 56 ===> 192.168.20.20)
2. Interval of "Protocol addresses" to one "IP address" (e.g.: 56 – 62 ===> 192.168.20.20)
3. 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 1 Byte, only for DNP3 and UNI protocols 2 Bytes.
■
IP
IP address to which Protocol address will be translated. This IP address is used as destination
IP address in UDP datagram in which serial SCADA packet received from COM1(2) is en-
capsulated.
■
UDP port (Interface)
This is the 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.). Following characters are not allowed:
" (Double quote)
` (Grave accent)
\ (Backslash)
$ (Dollar symbol)
; (Semicolon)
■
Active
You may tick/untick each translation line in order to make it active/not active.
■
Modify
Delete and Add buttons allow to add or to delete a line. The lines can be sorted using up
and down arrows.
