The I&M data sets 1...4 are stored permanently in parameters p8806...p8809. Significant
properties of these four parameters:
● They can be displayed in the STARTER expert list.
● The SINAMICS "Reset parameter" (p0976 = 1, p0970 = 1) function does not have any
effect on the content of parameters.
● I&M data sets are not changed when the alternative parameter sets are stored or loaded.
The transfer of parameter sets between a memory card and non-volatile device memory
does not have any effect on the I&M data sets.

p8808[0...53] Text with any comments or notes.
p8809[0...53] The parameter can be filled automatically by
the system, in which case it contains a stand-
ard value, namely, a functional check signature
for the change tracking by Safety Integrated.
The check signature has the following format:
The first four octets (0...3) contain the con-
•
tent of parameter r9781 index 0: "SI change
monitoring checksum (Control Unit)".
The second four octets (4...7) contain the
•
content of parameter r9782 index 0: "SI
change monitoring time stamp (Control
Unit)".
The remainder (octets 8...53) contains
•
zeroes.
Alternatively, a user can enter a user value
from an application and so overwrite the
standard value. Parameter p8805 specifies
which value is entered in p8809:
p8805 = 0 standard value entered
•
p8805 = 1 user value entered
•
When p8805 = 0 is set, the standard setting for
p8809 is restored again.
