DF1
Only the full duplex mode of DF1 is supported. Each frame in the Allen-Bradley DF1 protocol contains
the source and destination addresses in its header, so there is no difference between Master and
Slave in the Full duplex mode in terms of RipEX configuration.
Block control mode
List box: BCC, CRC
Default = BCC
According to the DF1 specification, either BCC or CRC for Block control mode (data integrity)
can be used.
Broadcast
According to the DF1 specification, packets for the destination address 0xFF are considered
broadcasts. Hence when Broadcast is On, packets with this destination are handled as broad-
casts.
Advanced parameters
ACK Locally
List box: Off, On
Default = On
If "On", ACK frames (0x1006) are not transferred over-the-air.
When the RipEX receives a data frame from the connected device, it generates the ACK
frame (0x1006) locally. When the RipEX receives the data frame from the Radio channel, it
sends the frame to the connected device and waits for the ACK. If the ACK is not received
within 1 sec. timeout, RipEX sends ENQ (0x1005). ENQ and ACK are not generated for
broadcast packets.
■
DNP3
Each frame in the DNP3 protocol contains the source and destination addresses in its header, so
there is no difference between Master and Slave in terms of the RipEX configuration. The DNP3
allows both Master-Slave polling as well as spontaneous communication from remote units.
There is not the option to set the Broadcast address, since DNP3 broadcast messages always
have addresses in the range 0xFFFD - 0xFFFF. Hence when Broadcast is On, packets with
these destinations are handled as broadcasts.
