SMC_TRAFOF_Gantry2 (FB)

FUNCTION_BLOCK SMC_TRAFOF_Gantry2

Forward transformation for two-dimensional gantries (X/Y). Each instance of SMC_TRAFOF_GANTRY2 can be connected to a visualization template named SMC_VISU_Gantry2 .

Note

For detailed information on transformations see Overview to SM_Trafo_POUs.
