Tip!
In addition to the functions of the LenzeMemDrv.lib, the operating system of the PLC includes
codes which allow the following memory−related functions:
·
Reading/writing data of a RAM block by means of autoincrement access" while the PLC
program is running (C0504 ... C0508).
·
Activating a read/write protection for the FLASH memory (C2006/C2007).
Detailed information can be found in the relevant PLC Manuals.
