Abstract
The objective of this work consists in achieving an industrial pediatric incubator network. The realization requires a general survey of different industrial networks regarding some point of view such as the protocol, the topology, the transmission support, and some technical and strategic criteria to be fulfilled. After this survey, a microcontroller network is achieved. The type of the structure network is the master/slave organized by bus. The used protocol for the communication is the RS485 in half duplex which limits the number of the slaves to only 32. The management of communications on the network is achieved by the master who uses the dialogue method of question/answer. Messages sent by the slaves are always destined only to the master. There is not a direct dialogue between the slaves. This property permits to guarantee the absence of collisions. The user is joined to the master through a link RS232. This link permits to know any slave's state.
