3.1 IntroductionT he FieldBus I/ O O ption consists of 2 parts. O ne part is an Any-Bus I / O M odule. T his module is a third part and comes fromHMS.

W e have chosen to buy this part because of the complexityand amount of fieldbuses.

3.2 HMST his is how H M S present themselves:

"H MS develops and supplies high tech electronics to quality consciouscustomers worldwide. H MS was one of the first companies to developinterfaces for all major fieldbus systems. T oday, ten years later, wehaveexpanded both thetechnology and our own skills. W e are now oneof theworlds leading companies in the fieldbus technology sphere, and are theglobal leaders in embedded O E M fieldbus modules for industrial prod-ucts."

4.1 IntroductionPR O FI BU S-DP is designed for high-speed data communicationat the device level. H ere, central controllers (e.g., PL C s/PC s)communicate with their distributed field devices (I / O , drives,valves, etc.) via a high-speed serial link. M ost of the data com-munication with these distributed devices is done in a cyclicmanner. T he functions required for these communications arespecified by the basic PR O FI BU S-D P functions in accordance

with E N 50 170.

4.2 Setting upBefore commencing communication with the FieldBus I/ Ooption, the option and the product will need some settings. Forproduct settings information see the product specific chapters.
