DNP3 parameters

Link parameters

DNP physical layer configures DNP3 for the TCP/IP or serial channel.

Unit address is the slave 16 bit link address. This value should be set between 1 and 65519,

since DNP3 reserves the top 16 addresses. All DNP3 devices sharing the same network

should have unique addresses.

Master address is the 16 bit link address at which the initial unsolicited message is sent.

The value should be unique, between 1 and 65519.

Serial port configures DNP3 for the selected serial channel only if DNP3 physical layer

is set for Serial. The serial port speed is set under Communication/COM1 and

Communication/COM2.

Time format can be set to Local or UTC.

CROB select timeout is the DNP3 select before operate timer.

Data link confirm enables or disables the data link confirmation. Options are: never, only

for multi-frame, messages or always. Option never is recommended in DNP Technical

Bulletin 1998 0402.

Data link confirm TO is the data link confirmation timeout in milliseconds.

Data link retries is the data link retry count from 0 to 65535.

Data Link Rx to Tx delay is the turnaround delay in milliseconds of the slave replies. The

timer starts at the trailing edge of the master's request.

Data Link inter char delay is the allowed inter character delay for incoming messages. The

timer starts with the reception of each character. When the timer expires because no

additional characters have been received, the IED regards the incoming message

complete. The unit of measure is a character time at the selected baud rate.
