PROFINET
PROFINET represents the communication standard for the automation which was made by PI
(PROFIBUS & PROFINET International).
The PROFINET IO communication is available when the PROFINET network card (LEC-S-NP) is
connected to the driver. The driver to which the PROFINET network card is connected is an IO device.
It supports two cyclic communication formats conforming to PROFI drive profile and CiA 402 drive profile.
It is compatible with the following control modes.
