DLMS Million Meter Simulator

ASEDLMS Meter Simulator enables Utilities, OEMs, and System integrators to evaluate Smart Meter Headend during development, validation, vendor selection, pilot deployment, and full rollout.


ASEDLMS Meter Simulator enables utility/System integrator/HES suppliers to evaluate HES/MDMS during their AMI project’s vendor selection stage or integration phase and identify issues before full meter deployment as well as to perform comparative assessment of different HES/MDMS systems. Some of the smart metering use cases which would be difficult or impossible using meters in operation can be simulated there by assisting end-users to make informed decisions. HES/MDMS developers can use Simulator for demonstrating capabilities and scalability of their HES/MDMS as well as for In-house validation and performance benchmarking.

Key Features

  • Able to simulate 1 million DLMS meter 
  • Supports automatic value changes based on user configured simulation type
  • Supports network latency simulation 
  • Supports Pull as well as Push
  • Supports DLMS TCP and UDP over IPv4 / IPv6

Large scale meter simulation

The ASE DLMS Meter Simulator allows to simulate one million DLMS meters and enables utilities, system integrators and Head End System manufacturers to run use cases and evaluate various key performance indicators including:

  • Data acquisition time
  • Communication failure rate
  • Command execution success rate
  • Firmware upgrade time
  • Alarm / Event real time notification handling efficiency

The tool allows user to simulate negative and very large/boundary values as well as data gaps in meters to verify HES/MDMS validation functions. Various practical communication issues such as network delays, meter going offline, etc. can be simulated to assess the impact on overall data acquisition time.

Single meter simulation

ASE DLMS Simulator when used for single meter simulation enables the developers and testers to overcome the unavailability of real meters during the development phase of any projects. Key advantages are:

  • Supports user to create their own meter templates with required objects, association and security
  • Cloning of a meter and simulation
  • Creation of a custom meter configuration and simulation
  • Multiple DLMS client users can connect to a single simulator
  • Traffic & Log module facilitates simulation and debugging of communication issues

This tool allows DLMS operations that are not possible using real meters such as simulating large/boundary values, negative conditions, timeouts, different types of security. A reduced development time for meters, meter interface cards, data concentrators and head end systems.
