Diagnostics and monitoring functions for peer-to-peer link
All transmitted and received useful data words can be checked (directly at the internal software
transfer point from/to peer driver) by means of display parameters r812 / r813 or r814 / r815.
Diagnostic parameters r799 or r809 provide information about the chronological distribution of errored
and error-free telegrams, as well as the nature of any communication errors that have occurred. A
watchdog can be set in P797 or P807 which can initiate a shutdown on faults (F012 or F013) in the
case of timeout. By connecting binectors B6031 or B9031 to the fault message triggers (using
P798=6031 / P808=9031), it is possible to acknowledge these fault messages even if the fault is
active continuously, thereby ensuring that the drive can still be operated manually after the peer-to-
peer interface has failed.
Important !
The serial interfaces for the peer-to-peer protocol are parameterized with the same parameters used
to configure the USS protocol, although the setting ranges are different in some cases (see Notes for
relevant parameters in Parameter List, Section 11).
Peer-to-peer communication, 4-wire operation
Serial linking of converter to converter (partners of equal status).
The signal flow can pass through the drives, for example, in a series connection. In this case, each
drive forwards the data after processing only to the next drive (classic setpoint cascade).
