Draft was circulated within IEEE in March 2023
PC37.251™/D23 1 Draft Standard for Common Protection 2 and Control Settings or Configuration 3 Data Format (COMSET)
This proposes a profile of SCL with elements based on IEC 61850 CDCs.
The profile would make minVal, maxVal, stepSize, unit mandatory
It also proposes extensions based on concepts from XML Schema that are not supported by the current ASG, ING, VSG
64-bit floating point values
integer values restricted to signed or unsigned 8bit, 16bit, 32 bit in addition to the configured minVal, maxVal
character strings with minimum & maximum string length
binary bitstrings represented by character strings with only 0 and 1 characters
byte array objects - character strings using base64 encoding
date/time in local or UTC time - date only, time only, date+time
settings to have default value as well as values per setting group
an additional <Val> element attribute, called ‘secondaryVal’, which allows vendors to record, along with the primary system quantity, the original secondary quantity
e.g. <Val comset:default="true" comset:secondaryVal=”100”>1000</Val>
Plus for part 7-4 add
GSET logical node is analogous to the existing GGIO node. It provides a generic, node to store settings information that doesn't adhere strictly to the IEC 61850 paradigm.
