)
Note!
ƒ In the system task, the memory access is processed at the same time as the
PLC program. This is why the processing time depends on the workload of
the system.
ƒ If you want to access the RAM memory from the IEC 61131 program, you
can use the functions of the LenzeMemDrv.lib function library for this
purpose.
If you want to access the RAM memory of the ECSxA... axis module by external controls or
PC tools, e. g. in order to manipulate the data of motion profiles online, you can implement
a RAM memory access by means of the following codes:
