Incorrect result in floating point calculations

Concerns the products:
EPL-10200 (Drive PLC all software versions)
EVS9300-EI (Servo PLC all software versions)

Reactions when the problem occurs:
Geometric and arithmetic calculations such as sine, square root, addition, ... using variables of the data type REAL (floating point) lead to an incorrect result.

When does the problem occur?
All calculations using variables of the data type REAL in time, event or interrupt-controlled tasks are affected.

Possible diagnoses:
None

Quick remedy/recommendations:
To obtain correct results in floating point calculations, the calculations must only be executed in the cyclic task (PLC_PRG).
