PNU Description
P797 Telegram failure time for G-SST2
The failure time set in this parameter is valid when setting P790=2 (USS
(G171)
protocol) or P790=5 (peer-to-peer) is selected.
(G173)
0.000
0.001...65.000 Time which may elapse between the receipt of two
Fault message F012 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).
Since the telegram transfer time is dependent on the set baud rate, the
following minimum setting values for P797 are recommended:
Baud rate as set in P793:
300 baud
600 baud
1200 baud
2400 baud
≥ 4800 baud
Note:
If the "Automatic restart" function is selected (P086>0) on the peer-to-peer
communication partner, then only a parameter setting of P797>P086 (on the
communication partner) is meaningful.

r799 Diagnostic information for G-SST2
Free-running counter, overflow at 65535
(G171)
(G173) 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 (USS prot. only)
i008:*) Block check error
i009:*) Incorrect telegram length:
With P792=3 or 4 only:
The length of the received telegram is ≠ P791 + P792
(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 P797. After the occurrence of a timeout error, this
counter is not activated again until the next valid telegram is
received.
*) Indices i006 to i009 are irrelevant for communication with the SIMOREG
