Bit 7: Acknowledge command (↑ "Acknowledge")

Condition	Positive edge change from L to H (L → H) in FAULT (007) state.
Result	♦ Reset all current faults after they have been transferred to the
	diagnostics memory.
	♦ STARTING LOCKOUT (008) if no further faults are active.
	♦ FAULT (007) if other faults are still active.
NOTE
	The acknowledge command is simultaneously effective from three
	sources (P565, P566 and P567) and always from the PMU!
Bit 8: Inching 1 ON command (↑ "Inching 1 ON") / (L "Inching 1 OFF")
Condition	Positive edge change from L to H (L → H) in the READY FOR ON state
	(009).
Result	♦ An ON command is automatically issued (refer to control word bit 0).
Condition	LOW signal
Result	♦ An OFF1 command is automatically issued (refer to control word
	bit 0).
Bit 9: Inching 2 ON command (↑ "Inching 2 ON") / (L "Inching 2 OFF")
Condition	Positive edge change from L to H (L → H) in the READY FOR ON state
	(009).
Result	♦ An ON command is automatically issued (refer to control word bit 0).
Condition	LOW signal
Result	♦ An OFF1 command is automatically issued (refer to control word

Bit 10: Control via PLC command (H "Control via PLC")

Condition	HIGH signal; The process data PZD (control word, setpoints) sent via
	the SCom1 interface of the CU, the CB/TB interface (option) and the
	SCom/SCB interface (option) are evaluated only in the case of an
	accepted command.
Result	♦ When several interfaces are in operation, only the process data of
	the interfaces sending an H signal are evaluated.
	♦ With an L signal, the last values remain in the appropriate dual-port
	RAM of the interface.
NOTE
	An H signal is displayed in visualization parameter r550 "Control
	word 1" if one of the interfaces sends an H signal!
