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.

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.
