%2 = String: Name of identifier
%3 = String: MD identifier
Definitions: To determine the name in the channel-specific tables for geometry axes and channel
axes an identifier already existing in the control has been used.
Reactions: - Alarm display.
- Interface signals are set.
- NC not ready.
- Mode group not ready, also effective for single axes
- NC Start disable in this channel.
- NC Stop on alarm.
