Parameters
Code Data type Access Info
Subcode Possible settings Presetting
C0504 − R / W Activate/deactivate write protection for RAM
When the write protection is activated, the RAM cannot be written via
LenzeMemDrv.lib codes or functions.
1 0 Deactivate write protection for RAM block 1 0
1 Activate write protection for RAM block 1
2 0 Deactivate write protection for RAM block 2 0
1 Activate write protection for RAM block 2
C0505 − W Offset address within the RAM block selected under C0506
0 {1} 65532 0
C0506 − W Selection of the RAM block for access under C0508/C0509
1 RAM block 1
2 RAM block 2
C0507 Double integer R Value read from the RAM block
After the RAM block has been read, the pointer to the memory address is
automatically incremented by 4 bytes.
C0508 Double integer W Value to be written in the RAM block
After the RAM block has been written, the pointer to the memory address is
automatically incremented by 4 bytes.
C0509 − R / W Check sum test
Note: Stop the PLC during the check sum test to avoid a time−out when reading
back the code.
0 Deactivated 0
1 Activated
Note!
The RAM access is processed in parallel to the PLC program in the system task. The
processing time therefore depends on the workload of the system.
You can use the functions of the LenzeMemDrv.lib function library to access the RAM from
your IEC 61131 program.
