Most of the device's internal IEC 61850 process data objects can be mapped to the IEC 60870-5-104 protocol. However, the potential protocol objects are not pre-mapped by default, so these objects should be mapped using Communication Management in PCM600.
The potential protocol objects have been pre-assigned into specific protocol ASDU types based on the source objects’ IEC 61850 common data class (CDC) types. This pre-assignment cannot be changed.
