PNU Description
p50797 P2P interface telegram monitoring time / P2P t_tel_monit
Description:
Sets the telegram monitoring time for the peer-to-peer interface (P2P
interface).
The set time is only effective in the "peer-to-peer interface" operating mode
(p50790 = 5).
p50797 = 0:
Monitoring is disabled.
p50797 > 0:
Monitoring is enabled.
Within the set time, after a valid telegram has been received, the next valid
telegram must be received. Otherwise, Fault F60012 is output.
Dependency:
See also: F60012
Note:
Telegram monitoring is activated in the following cases:
- From the reception of the first error-free telegram.
- After the electronics power supply has been switched-on.
- From the reception of the first error-free telegram after the telegram
monitoring responds (when the telegram monitoring time expires -
timeout).
The telegram monitoring time (p50797) is dependent on the selected baud rate
(p50793). For safe, reliable operation, the following minimum setting values are
recommended:
- 300 Baud → p50797 = 0.520 s (recommended minimum value)
- 600 Baud → p50797 = 0.260 s (recommended minimum value)
- 1200 Baud → p50797 = 0.140 s (recommended minimum value)
- 2400 Baud → p50797 = 0.080 s (recommended minimum value)
- 4800 Baud → p50797 = 0.040 s (recommended minimum value)
If, for the peer-to-peer communication partner, the "automatic restart" function
(p50086 > 0) is selected, then only the parameterization p50797 > p50086 (of
the communication partner) makes sense.
r50799 P2P/CCP diagnostics / P2P/CCP diag
[0...8]
Description:
Displays the diagnostics information for the peer-to-peer interface and the
interface to the SIMOREG CCP.
Index:
[0] = number of error-free telegrams
[1] = number telegrams with error
[2] = number of byte frame errors
[3] = number of overrun errors
[4] = number of parity errors
[5] = number of STX errors
[6] = number of block check errors
[7] = number of break errors
[8] = number of timeout errors
Note:
The error frequency is detected using free-running counters and when
65535 is reached, the particular counter is reset to 0.
For communication with SIMOREG CCP (p50790 = 6) the diagnostics
information in indices 5, 6 and 8 has no significance.
Possible error causes for STX errors:
- The start pause before STX was not maintained.
- STX error, i.e. not equal to 02.
Possible error cause for timeout errors:
- The telegram monitoring interval has expired (p50797).
r51560 CCP software version / CCP SW version
[0...1]
Description:
Displays the software version for the Converter Communication Protector
(CCP).
Index:
[0] = version release of the CCP software
[1] = version release of the software of the CCP boot sector
