Handling 64 bits data
Siemens hardware configuration tool does not support 64 bit data
type, so when writing larger numbers than 32 bit into the
configuration tool, this needs to be done according to below:
Example:
Total measuring range in measuring units = 2 36
2 36 = 6871947673610 = 0x00000010 00000000
4 byte 4 byte
Take the 4 least significant bytes (LSB) above and convert to
decimal:

0x00 00 00 00 = 0 = Total measuring range LSB
Then take the 4 most significant bytes (MSB) above and convert
to decimal:

0x00 00 00 10 = 16 = Total measuring range MSB
In the configuration software enter the decimal values:
Total measuring range LSB = 0
Total measuring range MSB = 16
8.9 Maximum master sign-of-life failures
With this parameter the number of allowed failures of the
master´s sign of life is defined. The default value is one (1).

Note: This parameter is only supported in compatibility
mode.
