AccessDNP3_SG: the DNP3 outstation does not re-order value changes based on the timestamp in the event buffer

Summary

The AccessDNP3_SG process gateway has been enhanced with an option to configure the event ordering. Either chronologic ordering or ordering in the order of observed occurrence (default) can be configured. The order of occurrence is in compliance with TB2018-001 published by the DNP users group.

Description

The AccessDNP3_SG process gateway has been enhanced with an option to configure the event ordering. Either chronologic ordering or ordering in the order of observed occurrence (default) can be configured. The order of occurrence is in compliance with TB2018-001 published by the DNP users group.

Information

1) ensure that the value changes are sent immediately by the IEC61850 server (buftime 0) so that two individual reports are sent instead of one, which would be processed by the IEC850 client driver in the order received

2) make use of zenon logic to restore the chronologic order of the variables received from the IEC850 client driver in the runtime
