3.2.6 Calculating the Checksums
The checksum (CRC) values are calculated from the PROFIBUS configuration
data, and compare the contents of the configuration file in the module with the
value reported by the processor. The checksum (CRC) value allows the
processor to verify that the configuration file is valid, and has not changed since
the last time the configuration file was imported to the processor. Any change to
the contents of the configuration file in either location changes the unique
numeric (CRC) value for the file.
If the checksum values do not match, the APP STATUS light illuminates on the
module.
1 On the PDPMV1 PROFIBUS Master Setup dialog box, click the C ALCULATE
C HECKSUMS button.
2 Make a note of the checksum values so that you can enter them later if
prompted.
Note: The recommended location for the files is the My Documents folder on your PC. The
configuration tool for the processor will use this folder by default.
3.2.7 Printing the Processor Network Memory Map
The inRAx Data Type dialog box uses the information about your PROFIBUS
Master and slaves to display the data types you configured. You will need this
information to determine the memory areas your application will use in the
CompactLogix processor.
