Configuration

Configuration file syntax is YAML. The objects drivers and interfaces are associative arrays where the key defines the type of driver/interface and the value is a list of instance name. For example in the configuration listed below we have one modbus instance with the name mb0.

Configuration for each single instance goes into driver.<driver_type>.<driver_name>.<setting_name> or interface.<interface_type>.<interface_name>.<setting_name>.

Sometimes it'd make sense to generate parts of the config via Python. For example if configuration items could be produced by iterating a list or loop. For this case these special YAML tags are helpfull:

• !py.Function <package>.<function>@<package path>

• !py.FileFunction <function>@<File.py>

• !File <File.yaml>

Will generate something like:
