AVEVA™ Plant SCADA

KNX Data Type Mappings

  • Last UpdatedAug 04, 2025
  • 3 minute read

The Date and Time data types will be read and written using the standard Plant SCADA time formats.

The driver will enforce the data ranges as specified for each data type.

When a write is issued to a controlled data type the controlled bit will be set to 1.
