The offset of the results output (ID-code + results) within the output area of the data buffer is determined
by the set number of control signals set (8 per byte).
Formats for floating decimal numbers
Measurement results and limits for torque, angle, and gradient are shown as floating decimal numbers
with a varying number of digits. The decimal character is output as a decimal point. The number of digits
before and after the decimal point is:

The number and order of the result values is fixed. The output of parameters and/or step results of docu
steps is not possible.
XML and IPM output of torque values is always with two decimals.
