Commissioning
Fig. 25: Inserting a task
In the case of less powerful devices (e.g. CX1000, CX9000 with E-bus), the CPU load may reach its limits.
However, the performance can be improved again by means of the following considerations/measures:
• Is it possible to work with just one PLC task?
• Does the cycle time have to be 1 ms?
• If two tasks are used, can the PLC task time be shortened?
• Will several virtual PROFINET devices by required?
6. PDO Mapping
The PDO mapping describes how the PROFINET data is to be represented in the EtherCAT. The
"Submodule data" setting should be used if TwinCAT is used.
