My TCP port
Default = 502 [1 - 65 535]
TCP port used for Modbus TCP in RipEX.
•
TCP Inactivity [s]
Default = 120 [0 - 16 380]
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 con-
nected 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
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
