Abstract
This work presents the realization of a platform for testing and validating distributed real time systems (DRTS), by following a methodology of development. Our main contribution remains the realization of an industrial communication bus (FIP: Factory Instrumentation Protocol) implemented on an Ethernet platform. It focuses on improving the response time of the bus. For that, we use a deterministic implementation of FIP’s services (variables identification, transmission functions, …) by exploiting the TCP/IP stack. The periodic communications are monitored by real time periodic threads, run on RTAI kernel.

Notes
- 1.
Part of the bus that can be, a computer, an automaton, a sensor or an actuator.
- 2.
Open source, preemptible without latency problems of operating system calls and has a known gigue.
- 3.
ARP: protocol of layer three which makes the correspondence between Internet logical addresses and MAC addresses.
- 4.
Used by switches and routers to avoid loops on a WAN.
