9. Entering parameters
The following parameter data is stored in the GSD file in the form of 32-bit values
(double words, format "unsigned32"):
- Steps per revolution
- Total resolution
Many configuration programs for Profibus masters (including also Step7
®
from SIEMENS) do not support this
word length during parameter input. The upper and lower 16 bits of these parameters ("hi" and "low" block)
must accordingly be entered separately, and in decimal form.
In the case of parameters smaller than 65535 (16 bit), all that is necessary is to enter the block "hi" = 0 and
the parameter itself is entered directly in the "lo" block.
Parameters greater than 65535 (16 bit), must be separated beforehand using the formula described below
and then recalculated. A calculator with hexadecimal function of the type provided among the "Windows
accessories" is helpful here.
Conversion of the required parameter value from the decimal format into hexadecimal format
Subdivision of the hexadecimal value into two blocks, "hi" and "lo". The block length in each case is two
words
Conversion of the hexadecimal format of the two blocks "hi" and "lo" back into decimal format
Input into the input mask using the decimal format
Example
Total resolution
= 3600 steps per revolution x
256 revolutions
= 921600
Conversion into hexadecimal format = E1000
Subdivision into “hi” = 000E
Conversion into decimal format = 14
Subdivision into “lo” = 1000
Conversion into decimal format = 4096
Total measuring range (units) hi = 14
Total measuring range (units) lo = 4096
Steps per revolution = 3600 steps = 3600
Measuring units per rev. hi = 0
Measuring units per rev. lo = 3600
