PROFINET and Other Drivers

The PROFINET controller and device can run on one and the same Ethernet adapter with other drivers, such as Modbus/TCP or Ethernet-IP. However, they require exclusive access to the low-level Ethernet component (SysEthernet). Therefore, for example, they cannot run parallel with EtherCAT on one adapter. If multiple Ethernet adapters are available, then one PROFINET driver each (controller or device) can be operated there.

PROFINET and RTE runtime system

At this time, only one instance of a PROFINET driver is possible in a project. In contrast, parallel operation with EtherCAT is possible (on different Ethernet adapters).

Note

This applies to CODESYS versions < V3.5 SP11.
