Hello,
I am looking for a way to get the arcus cosine of a value.
How does the function look like? I tried the following functions:
ACOS; ARCOS; ACS; ARCCOS but nothing works.

Thank you for your answer.
Kind regards,
Philipp Ziegler

Hi,

in IEC 61131-3 there is a ACOS function defined for ANY_REAL (i.e., REAL and LREAL). If you have a different data-type you can use the convert functions defined in IEC 61131-3 (e.g., INT_TO_REAL).
