Checksums

7.6.1

Overview

Based on Safety Integrated checksums and signatures, you can compare the actual state of the
machine with the original state when delivered, which is documented in the acceptance report.
The checksums are displayed in the SINUMERIK ONE Commissioning Tool in the diagnostics
area.
● The individual F-blocks have signatures, and the safety program has an F-collective
signature. These checksums for the safety program are displayed in the TIA Portal as well
as in the safety summary (hardcopy).
● The F-PLC has an F-collective signature, hardware F-signature, software F-signature.
● There are SINAMICS parameters with reference checksums (defined when commissioning)
- and actual checksums for CU, MM and motion monitoring functions, which are checked
when the SINAMICS S120 drive runs up. SINAMICS alarms 201650/230650 and/or
201680/230680 are output if the checksums differ.
See: SINAMICS checksums (Page 327)
● Additional master checksums and global checksums, which are calculated from the actual
checksums mentioned above, are displayed in the SINUMERIK ONE Commissioning Tool.
SINUMERIK MC does not compare these higher-level checksums with reference
checksums - and also does not save them.
See: Calculating the global checksums/master checksums (Page 326)
The global checksums/master checksums are displayed in the diagnostics area of the
SINUMERIK ONE Commissioning Tool; this allows you to easily identify differences
between the actual state and reference state.
See: SI checksums (Page 320)
