Diagnostic information for G-SST2
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 (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.

Number of process data for G-SST3
When P800 = 0 or 9 is selected:
Parameter is irrelevant
When USS protocol (P800=2) is selected:
Number of PZD elements
0 No process data are expected or sent in the USS protocol
1...16 Number of process data words in USS protocol (same number
applies to transmission and receipt)
The received PZD elements (1 to max. 16) are available at
connectors (K6001 to K6016) and, in some cases, bit-serially at
binectors for "internal wiring" purposes.
The PZD elements to be transmitted (1 to max. 16) are selected
in parameters P804.01 to P804.16.
When peer-to-peer (P800= 5) is selected

Length of parameter jobs for G-SST3
This parameter is effective only when P800=2 (USS protocol).
0 No PKW data
are expected or sent in the USS protocol.
3, 4 3 or 4 PKW data words
are expected in the USS protocol and 3
or 4 PKW data words are also sent (for transmission of
parameter values).
