These are the communication protocols with PLC, embedded systems, pc, Scada systems and etc.
Fieldbus: It’s the communication network of sensor, servo motor and pc in automation systems.
Profibus: It’s used in communication systems that are considered as standard, complex and critical with high speed and developed by PLC.
Canbus: It’s developed to provide data transfer via software from a cable and disposes cable mess. It’s highly preferred in the industry thanks to perfomance and safety criteria.
