FUNCTION_BLOCK SMC_ReadCAM
This function block is designed for loading a cam at runtime and making it available for the modules MC_CamTableSelect and MC_CamIn. The cam to be loaded has to be created within the cam editor before and saved in a "*.CAM" file (see SMC_WriteCAM). The size of a loadable cam is limited by the global constants gc_SMC_FILE_MAXCAMEL (number of elements) and gc_SMC_FILE_MAXCAMTAP (number of cam switch actions).
