The work presented is this communication intends to evaluate the possibility of using Ethernet to perform integration in manufacturing systems. The principal obstacle is its random medium access time that is not suitable to real-time systems. It refers to some experimental tests based on a case study, which showed that Ethernet can be a correct choice in soft real-time systems. Furthermore, it is discussed the design and implementation issues behind the alteration of the medium access control of Ethernet to support real-time, without requiring any modifications of hardware.
