• The change from one state to another is done in a 1 ms cycle. If, at the same time, several state
change requests exist, the state with the higher priority is processed first (see the following ta-

• C137
displays the current device state.
• C150
(status word) provides a bit coded representation of the current device state via bits 8 ... 11
(see table below).
