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.
