The EtherCAT® fieldbus system is a very powerful real-time Ethernet fieldbus system which makes the individual I/O resources easily available for the I/O modules with the configurator integrated into CODESYS®. The application software developer has direct access to all of the sensors and actuators connected via the I/Os in one project with no protocol or driver programming.
Even a very widely distributed system with a lot of I/O slaves can thus be mapped in the programming system as if all of the sensors and actuators were simply connected to the master control device. The high real-time capability means that the times for the I/O update in the master are negligible. Even the most complex control circuits with high real-time requirements can be distributed in almost any way in the control system network.
