Table 1. Supported data types in data sets

Data type

Description

ST and MX

Partly supported

CF, SG and SP

Supported but not recommended

CO

Not supported

According to the standard, it is write-only.

OR and BL

Supported

However, since the relay does not natively support the types, the engineer needs to define the used ST data behavior in Application Configuration.

Array

Not supported

VisString

Not supported

The data is not operational.
