DLMS PROTOCOL
The DLMS (Device Language Message Specification) is a protocol for standardising metering
communications within the IEC.
The DLMS is independent from the communication system used and guarantees the interoper-
ability of energy meters from different manufacturers.
This protocol enables the recording and sending of different types of parameters and events.
A logic device (Device) has 4 types of possible association or access:
-
Public client (PC)
, server address 16.
-
Management client (MC)
, server address 1.
-
Reading client (RC)
, server address 2.
-
Update firmware client (FC)
, server address 3.
Depending on the type of association, the user has different privileges for each one of the ob-
jects of the protocol:
-
, No access
R
, Read Access
W
, Write Access
E
, Execution Access
