IEC 61850 MSQI Module
Module icon
Overview
It maps the appropriate ION values to their IEC 61850 counterparts. The MSQI Logical Node is used to represent the sequences in a three/multi-phase power system. Sequence calculations are made available on the meter through the Symmetrical Components ION modules. Only one instance of this module can exist. Because this module is specific to supporting the IEC 61580 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 protocol document.
Inputs
By default, the MSQI module inputs are linked to the outputs of the current and voltage Symmetrical Components modules.
These registers are linked to the PosSeqMag and the PosSeqPhs output registers of the current Symmetrical Components module, which provide the magnitude of positive sequence current and the phase angle of positive sequence current, respectively. Units are Amps.
These registers are linked to the NegSeqMag and the NegSeqPhs output registers of the current Symmetrical Components module, which provide the magnitude of negative sequence current and the phase angle of negative sequence current, respectively. Units are Amps.
These registers are linked to the ZeroSeqMag and the ZeroSeqPhs output registers of the current Symmetrical Components module, which provide the magnitude of zero sequence current and the phase angle of zero sequence current, respectively. Units are Amps.
These registers are linked to the PosSeqMag and the PosSeqPhs output registers of the voltage Symmetrical Components module, which provide the magnitude of positive sequence voltage and the phase angle of positive sequence voltage, respectively. Units are Volts.
These registers are linked to the NegSeqMag and the NegSeqPhs output registers of the voltage Symmetrical Components module, which provide the magnitude of negative sequence voltage and the phase angle of negative sequence voltage, respectively. Units are Volts.
These registers are linked to the ZeroSeqMag and the ZeroSeqPhs output registers of the voltage Symmetrical Components module, which provide the magnitude of zero sequence voltage and the phase angle of zero sequence voltage, respectively. Units are Volts.
Setup registers
The MSQI module has no setup registers.
Output registers

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.
