* Channel Error Type is PROFIdrive profile specific. See list of Channel Error
Types in the table below.
Alarm mechanism
When a fault situation occurs the RETA-02 adapter will send an
alarm notification (see table below), which the master station has
to acknowledge. Alarm notifications can be acknowledged, viewed
and handled with e.g. Siemens S7 blocks OB82, OB83, OB86 and
OB122. The block OB82 is used to make sure that the drive does
not go to stop mode during a diagnostic alarm. The OB83 is called
if module is inserted or removed from the system or if it is
modified. OB86 indicates if there is a failure or event in the
distributed periphery. If the CPU calls a device that is not
accessible the OB122 is called.
