You could try with "iMovementType" member of AXIS_REF_SM3 struct. https://content.helpme-codesys.com/en/libs/SM3_Basic/Current/SM3_Basic/DriveInterface/AXIS_REF/AXIS_REF_SM3.html https://content.helpme-codesys.com/en/libs/SM3_Basic/Current/SM3_Basic/DataTypes/DriveInterface/SMC_AXIS_TYPE.html

So it's currently mapped to an array of BYTES? Can you create a UNION? TYPE sBytesString : UNION AsBytes: ARRAY[0..127] OF BYTE; AsString: STRING(128); END_UNION END_TYPE Map it to the bytes, read it in the STRING!

Started playing with the idea of ditching windows for linux, one of the obstacles would be Codesys development. Alternatives: - linux with wine? - Run windows/codesys through virtual machine I guess a vm is the way to go? Anyone out there that could share their experience?

Post by tk096 on Sm3_math ^{CODESYS Forge talk (Post)}
Hi, SM3_Math is actually an internal library of SoftMotion. You can use it. The only restriction is that there is no compatibility guarantee - meaning that POUs in the library may change their interface, get moved/renamed/removed... in future versions of SoftMotion.
