The command-line interface (CLI) to the Adapter provides some helpful commands, including:

  • show all available commands (help)
  • run the Adapter
  • generate a default top-level config file
  • generate a default protocol-specific config file for specified profiles
  • list all the provided protocol plugins


Prints a short description of all the available commands and parameters.


openfmb-adapter -h


-h, --help
show this help message
-l, --list
list available plugins
-v, --version
display version information
-c, --config
run with the specified config file
-g, --generate
generate the specified config file
-s, --schema
generate a JSON schema
-p, --plugin
the plugin for which to generate configuration
-f, --profile
profile to generate

Generate top-level configuration#

A default top-level configuration may be generated using the -g flag. This file is needed when running the Adapter (see Running the adapter).

openfmb-adapter -g config.yml

Generate configuration for a plugin#

Some plugins, notably the Adapter-type protocol plugins, need extra configuration in separate files. The output file is specified with the -g argument. The plugin for which the config is generated is specified with the -p argument. The desired profile is specified with the -f argument.

Multiple profiles can be generated for a single configuration file by providing multiple -f parameters:
openfmb-adapter -g dnp3-master.yml -p dnp3-master -f SolarReadingProfile -f SolarStatusProfile

Generate configuration JSON schemas#

Each YAML configuration file has JSON schemas that can be printed to a file to help with writing valid configurations.

To generate the top-level schema, run the following:

openfmb-adapter -s config.json

To generate the schema for a particular plugin, run the following:

openfmb-adapter -s dnp3-master.json -p dnp3-master

The --pretty-print argument can also be used to produce human-readable schema files. Note that these files are particularly large for plugins and pretty-printing should be used only for debugging purposes.

To learn how to leverage these schemas in your editing environment, see the Schemas page.

Running the adapter#

The adapter is run using the -c flag. To stop the adapter, hit Ctrl-C on the keyboard.

openfmb-adapter -c [config.yml]

List plugins#

All available plugins compiled in this instance of the adapter can be listed using the -l flag.

openfmb-adapter -l


available plugins:
capture - captures published OpenFMB messages to a replayable file format
dds-rti - publish/subscribe to DDS using RTI bindings (requires run-time license)
dnp3-master - maps openFMB to the master side of the DNP3 protocol
dnp3-outstation - maps openFMB to the outstation side of the DNP3 protocol
log - pretty prints profiles to the log
modbus-master - maps OpenFMB to the Modbus protocol
modbus-outstation - maps the Modbus protocol to OpenFMB
mqtt - publish/subscribe to a MQTT broker
nats - publish/subscribe to a NATS server
replay - replays captured OpenFMB messages from a file
timescaledb - saves all the published messages to a TimescaleDB


The git commit date and hash of the code compiled in this instance of the adapter can be listed using the -v flag. The hash can be used on GitHub to retrieve the exact code used, simply go to{HASH}.

openfmb-adapter -v
