Due to the software tool STEP7 32-bit parameter values (e.g. total measuring range, software limit
switches) have to be divided into high and low word.
Example:
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.
