The framed objects are coupling objects for Compax3 - Compax3 coupling via
HEDA.
Please note that the corresponding controller components must be deactivated for
the coupling:
When coupling the velocity (O2219.14): O100.1 or O100.2=1063 (see object
description)
When coupling via current (O2220.2): O100.1 or O100.2=1031 (see object
description)
O100.1 is only copied into O100.2 upon activation of the controller, the controller
can be influenced in active state with the aid of O100.2
