P786	USS bus address for G-SST1
*	This parameter is functional only when P780=2 (USS protocol). Address via
(G170)
	which the unit can be addressed in USS bus operation.
P787	Telegram failure time for G-SST1
	The failure time set in this parameter is valid when setting P780=2 (USS
(G170)	protocol) is selected.
	0.000	No time monitoring
	0.001...65.000 Time which may elapse between the receipt of two
		telegrams addressed to the unit before a fault message
		is activated.
	Fault message F011 is activated if no valid telegram is received within this
	time period.

Note:

The telegram monitoring function is active

•from the receipt of the first error-free telegram after connection of the electronics power supply

•from the receipt of the first error-free telegram after the telegram monitor has responded (i.e. monitoring timeout).

P788	Source for activation of F011
*	Selection of binector which will activate fault message F011 when it
(G170)
	switches to log. "1"
	2030 = binector B2030
	2031 = binector B2031
r789	Diagnostic information for G-SST1
(G170)	Free-running counter, overflow at 65535
	i001:	Number of error-free telegrams
	i002:	Number of errored telegrams:
		Byte frame, parity, overrun or BCC error
	i003:	Number of byte frame errors
	i004:	Number of overrun errors
	i005:	Parity error
	i006:	STX error:
		Start interval before STX not observed,
		telegram residual transfer time not observed,
		delay time of LGE character too long,
		erroneous STX, i.e. ≠ 02
	i007:	Violation of telegram residual transfer time
	i008:	Block check error
	i009:	Incorrect telegram length:
		With P782=3 or 4 only:
		The length of the received telegram is ≠ P781 + P782
		(Note: If the received values are correct, they will be processed
		even when this error has been detected)
	i010:	Timeout error:
		No valid telegram has been received for a period exceeding the
		setting in P787. After the occurrence of a timeout error, this
		counter is not activated again until the next valid telegram is
		received.
