Due to the old versions of software tool STEP7 32-bit parameter values (e.g. total measuring range,
software limit switches) have to be divided into high and low word. This is not necessary with the new
STEP7 versions and our actual GSD file.
Example for the old GSD file:
Decimal Hexadecimal Hexadecimal Decimal (to be entered)
129600 00 01 FA 40 High word 00 01 1
Low word FA 40 64064
The decimal value „1“ has to be entered into the high word parameter field, the value 64064 into the low
word parameter field.
Or:
Divide the value by 65536; enter the integer part of the result into the high word parameter field, the
remainder into the low word field.
129600 / 65536 = 1.977539 → integer part = 1 → high word = 1
129600 – 1 x 65536 = 64064 → remainder = 64064 → low word = 64064
It is also possible to enter the parameters directly as hexadecimal code. However this is very complicated
and it should be avoided if possible.
