An arrangement operable to communicate with a fieldbus network and operate an attached relay and a method for implementing such arrangement is provided. The arrangement and method provide conventional discrete outputs from a fieldbus device using standard fieldbus function blocks, such as those used for Foundation짰 and Profibus짰 fieldbus networks. The arrangement and method may facilitate the integration of traditional discrete relay functions into these more advanced digital fieldbus networks, and also utilize additional functions available to standard Foundation짰 fieldbus and Profibus짰 fieldbus network devices.

What is claimed is: 1. An arrangement operable to communicate with a fieldbus network, comprising: at least one processor capable of receiving fieldbus function blocks; and at least one relay which is at least one directly or indirectly coupled to the at least one processor, wherein the at least one processor is capable of controlling the at least one relay using at least one of the fieldbus function blocks. 2. The arrangement of claim 1, wherein the at least one processor receives power from the fieldbus network. 3. The arrangement of claim 1, wherein the fieldbus network operates according to a particular protocol, and configured to make available status data, and wherein the at least one processor generates the status data. 4. The arrangement of claim 1, wherein the at least one processor monitors line activity on the fieldbus network, demodulates at least a first signal received from the fieldbus network, and modulates at least a second signal provided to the fieldbus network. 5. The arrangement of claim 1, wherein the at least one processor performs management functions. 6. The arrangement claimed in claim 1, wherein the at least one relay is an optically isolated solid state relay. 7. The arrangement of claim 1, further comprising a liquid crystal display capable of receiving data from the at least one processor. 8. The arrangement of claim 1, wherein the at least one relay is capable of being activated by a magnetic tool. 9. The arrangement of claim 1, further comprising at least one memory communicatively coupled to the at least one processor. 10. The arrangement of claim 9, wherein the at least one memory includes a random-access memory (RAM). 11. The arrangement of claim 9, wherein the at least one memory includes a read-only memory (ROM). 12. The arrangement of claim 9, wherein the at least one memory includes a flash memory. 13. The arrangement of claim 9, wherein the at least one memory includes an electronically erasable/programmable read-only memory (EEPROM). 14. The arrangement of claim 1, wherein the function blocks which may be utilized by the at least one processor include at least one of a resource block, a flip flop and edge trigger block, an analog alarm block, a timer block, a discrete output block, an arithmetic block, an input selector block, a PID control block, and a step output PID block. 15. The arrangement of claim 1, wherein the at least one relay is configured to control at least one device which is incapable of at least one being connected to or operating on the fieldbus network, and wherein the at least one relay is controlled by the at least one processor to control the at least one device. 16. A method for operating at least one relay coupled to a fieldbus network, comprising: executing at least one fieldbus function block; and operating the at least one relay based on at least one output of the execution of the at least one fieldbus function block. 17. The method of claim 16, wherein the at least one processor receives power from the fieldbus network. 18. The method of claim 16, wherein the fieldbus network operates according to a particular protocol, and configured to make available status data, and wherein the at least one processor generates the status data. 19. The method of claim 16, wherein the at least one processor monitors line activity on the fieldbus network, demodulates at least a first signal received from the fieldbus network, and modulates at least a second signal provided to the fieldbus network. 20. The method of claim 16, wherein the at least one processor performs management functions. 21. The method of claim 16, wherein the at least one relay is an optically isolated solid state relay. 22. The method of claim 16, wherein the at least one relay is capable of being activated by a magnetic tool. 23. The method of claim 16, wherein the function blocks which are executed include at least one of a resource block, a flip flop and edge trigger block, an analog alarm block, a timer block, a discrete output block, an arithmetic block, an input selector block, a PID control block, and a step output PID block. 24. The method of claim 16, further comprising controlling at least one device using the at least one relay, wherein the at least one device is incapable of at least one being connected to or operating on the fieldbus network, and wherein the at least one relay is controlled by the at least one processor to control the at least one device. 25. The method of claim 16, wherein the execution of the at least one fieldbus function block and the operation of the at least one relay are performed within a single field device.
