Eliminated function restriction
Lenze PLCs offer the opportunity to copy parts of the variable memory of the PLC (e. g. global variables or arrays) into a 'backup memory'. As a result, e. g. recipe memories or measured-value memories can be implemented. Application RAM 1 and 2 represent this 'backup memory' and can be written and read by means of functions of the LenzeMemDrv.lib.
After mains connection or 'Reset original' the data under Application RAM 1 and 2 were not deleted – the content was not defined.
After mains connection or 'Reset original' the data under Application RAM 1 and 2 are correctly set to zero.
