Connectivity and interoperability

The DNP3 adapter can connect to one or more DNP3 compliant outstations through TCP/IP connections. The DNP3 adapter will not communicate with other DNP3 master stations. The total number of outstations that the adapter can connect to varies across different installation environments.

The DNP3 adapter is designed to run as a Level 1 (DNP3-L1) master station. DNP3-L1 defines minimum requirements for all DNP3 compliant devices. However, the adapter makes use of some Level 2, Level 3, and Level 4 functions. Some DNP3 compliant devices cannot support these same features. Any functionality described in this documentation not needed for Level 1 compliance is noted as such.

Refer to the outstation documentation before using these features, as the adapter must be configured to only use the outstation's supported features.

Note: The 1.2 release includes updates to internal libraries. Due to these updates, the DNP3 adapter no longer supports Group 50 Variation 4 messages (Time and Data - Indexed Absolute Time and Long Interval).
