5. DNP3 Ethernet Communication Setup Configuration Utility

PXM 4/6/8K DNP3 Ethernet Communications User Manual

MN150005EN January 2017 www.eaton.com

5.3.2 DNP Data Link Layer

In this section, the User can set the parameters related to

the DNP Data Link layer that follows.
1. DNP Link Layer Confirmation

For this parameter, the User can select three options as

shown below.

●

●

Never

The PXM meter shall never expect or wait for

a confirmation message from the DNP master

in response to the data link layer frame sent to

the master.

●

●

Sometimes

The PXM meter shall expect or wait for a con-

firmation message from the DNP master in

response to the data link layer frame sent to

the master in certain cases only.
If the data link frame contains events or related

data, then the PXM meter shall expect a data

link confirmation from the DNP master. If the

data link frame contains static information, then

the PXM meter shall not expect a data link con-

firmation from the DNP master.

Figure 10. Link Layer Confirmation Choices.

Choosing this option may add overhead at the

DNP master. Therefore, it needs to be selected

carefully.

●

●

Always

The PXM meter shall always expect or wait for

a confirmation message from the DNP master

in response to a data link layer frame sent to

the master.

2. Link Layer Retries

This parameter indicates how many times the PXM

meter shall attempt to retransmit the DNP link frame in

case of failure of DNP link layer confirmation from the

DNP master. Range of this parameter is from 0 to 15.
It is obvious that if the link layer confirmation parameter

is set to the option “Never”, then the link layer retires

parameter does not hold any significance since the

PXM meter shall never attempt retransmission of link

frame.
