Activation source
The "DAS+ activation source" register (0x0FD4) shows several activation sources.
• The COM A and COM B communication module communications are subdivided internally
depending on their protocol. Each protocol is a separate activation source.
• In the case of the COM 190 communication module, PROFINET and Modbus TCP are
separate activation sources.
• The Bluetooth and USB-C interface TUI600 also has two activation sources. USB-C and
Bluetooth are treated as separate activation sources internally. If the DAS+ maintenance
mode is activated via Bluetooth, for example, it must also later be deactivated via
Bluetooth.
