4.2 DNP3 protocol (option)
Parameter : Baud Rate
Options : 9600, 19200, 38400, 57600, 115200 bps.
Description
: baud rate for the RS-485 link.
Parameter
:
Format
Options : 8N1, 8E1, 8O1, 8N2.
Description : symbol transmission format, where:
◦
8N1 : 8 data bits, no parity, 1 stop bit.
◦
8E1 : 8 data bits, even parity, 1 stop bit.
◦
8O1 : 8 data bits, odd parity, 1 stop bit.
◦
8N2 : 8 data bits, no parity, 2 stop bits.
Parameter : Address
Options : 0x0000 to 0xFFEF.
Description : DNP3 outstation address in hexadecimal notation.
Parameter
: Application Layer Confirmation
Options
: Only when transmitting events or multi-fragment responses, Always.
Description
: Selects when the MFC-202/P outstation should request application layer
confirmations.
Parameter : Maximum Inter-Octet Gap
Options : 2 to 100 ms.
Description : The DNP3 specification states that frames should not have inter-octet gaps.
In accordance, the MFC-202/P never inserts inter-octet gaps when transmitting data.
However, we allow the option to tolerate gaps in incoming transmissions. Frames featuring
inter-octet gaps larger than the Maximum Inter-Octet Gap will be quietly dropped.
Parameter : Backoff Delay (Fixed)
Options : 1 to 100 ms.
Description : See description for Backoff Delay (Random) .
Parameter
: Backoff Delay (Random)
Options
: 1 to 100 ms.
Description
: The MFC-202/P is designed for multi-drop scenarios where more than
one outstation may transmit over the same line. To handle collision avoidance, a backoff
