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.

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.
