P787 Telegram failure time for G-SST1
The failure time set in this parameter is valid when setting P780=2 (USS
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).

r789 Diagnostic information for G-SST1
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.
