ProfinetDeviceInstance (FB)

FUNCTION_BLOCK ProfinetDeviceInstance

An instance of this function block represents a Profinet field device.
The internal protocol stack has to be configured with DeviceIdentification and module configuration (method ConfigureDevice() or ReconfigureModules()).
For operation, a cyclic call of methods ReceiveData() and SendData() is required. Additionally acyclic service requests have to be processed by cyclic call of method ProcessServices().
A sample project can be found on CODESYS forge.
