IEC 61850 MMXU Module
Module icon
Overview
It maps the appropriate ION values to their IEC 61850 counterparts. The MMXU Logical Node provides per-phase and total current, voltage and power flows normally used for operational purposes such as power flow supervision and management, measurement displays, state estimation, etc. Only one instance of this module can exist. Because this module is specific to supporting the IEC 61850 protocol, it can be deleted if IEC 61850 is not required.
For more information about IEC 61850, please refer to the IEC 61850 and ION Technology technical note.

Events produced by the module are recorded in the Event register. Possible events and their associated priority numbers are shown in the following table.
Event priority group | Priority | Description |
---|---|---|
Reset | 5 | A module reset has occurred. |
Setup Change | 10 | Input links, setup registers or labels have changed. |
Information | 25 | not available input caused output to go not available. |
The Event output register stores the following information for each ION event: time stamp, priority, cause, effect, and any values or conditions associated with the cause and effect.
