Abstract :
We propose a temperature smart sensor (TSS) having the capability of interconnection on fieldbuses compatible both with IEC 61158 and EN 50170 standards. In this aim TSS has a versatile programmable electrical interface corresponding to the TIA/EIA-485-A standard. The communication protocol supports both the IEC 870-5-1 specification of Telecontrol Equipment and Systems and the Fieldbus Foundation specification for isochronous transmission. TSS utilizes thermocouples or thermo resistances as sensitive elements, so several types and ranges are available. The paper presents the hardware and software architecture, with details on the communication interface and software. A dedicated section refers to the local software facilities and insists on the versatility in programming functional parameters. Finally, some of the advantages in industrial control applications of this device are underlined
