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 protocol document.

NOTE: The registers and settings available in this module depend on the device or node you are configuring, as well as its firmware and template versions. Not all registers or settings are available on all devices or the Virtual Processor, and labels may vary.


The GGIO Custom Analog module is configurable through Power Monitoring Expert or ION Setup software to map up to 16 analog values from ION to IEC 61850.

Analog Input 1-16

These registers can be connected to any numeric register.

Setup registers

The GGIO Custom Analog module has no setup registers.

Output registers

These registers are formatted and named according to IEC 61850 protocol standards. Modifying these register labels may cause issues with your IEC 61850 data.

AnIn1.instMag ... AnIn16.instMag

These registers contain the Analog Input 1 - 16 input values.

AnIn1.mag ... AnIn16.mag

These registers are taken from the Analog Input 1 - 16 inputs, and are used in IEC 61850 for deadband and report triggering functions.
