IEC 104 exchanged
...
ASDU configuration
In this chapter we will describe the configuration of the exchanged ASDU. This configuration allow to specify a list of supported ASDU types and a list of ASDU objects. The protocol plugin is expected to make some controls against each entry of the configuration to check:
- if CA of ASDU is known otherwise throw an error message.
- if IOA is known otherwise throw an error message.
- if type of ASDU is known otherwise an error message.
- The label attribute shall be used to populate the Fledge's DataPoint Asset Name attribute.
