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 Unit 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 broad-
casts. Broadcasts are not supported with the mobile network.

• Advanced parameters
○ ACK Locally
List box: Off, On
Default = On
If "
On ", ACK frames (0x1006) are not transferred over-the-air.
When the Unit receives a data frame from the connected device, it generates the ACK frame
(0x1006) locally. When the Unit receives the data frame from the mobile network, it sends the
frame to the connected device and waits for the ACK. If the ACK is not received within 1 sec.
timeout, Unit 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 M!DGE configuration. The DNP3 allows both
Master–Slave polling as well as spontaneous communication from remote units.
• Broadcast - Note: There is not the option to set the Broadcast address, since DNP3 broadcast
messages always have addresses in the range 0xFFFD – 0xFFFF. Broadcasting is not supported
by mobile networks, thus it is not possible to set the broadcast to On..
