New Features

Profinet

• Improves the transmission of value changes to the Data Point Manager for more reliable communication. 

METZ Connect

• Supports the Modbus function "Read Device Identification (0x2B/0x0E)" for METZ Connect modules.

Bug fixes

Gateway (UGW)

• Fixes an issue where the number of installed drivers was not restored correctly after a backup or firmware update.

Profinet

• Fixes communication issues after a restart.
