Standards Certification Education & Training Publishing Conferences & Exhibits Secrets to Success with Foundation Fieldbus Ian Verhappen MTL Instruments Group

Key Points Foundation Fieldbus –What is different, what is the same Installation Tips Documentation What’s New

FOUNDATION™ Fieldbus H1 4-20mA P.S. fieldbus P.S. –Fieldbus devices are connected in parallel on the bus, which carries digital data from/to all the devices on the bus. –Fieldbus devices provide information to all other devices on the network. –A multidrop fieldbus does not have the shortcoming of point-to-point wiring. –Two devices are better than one!! Courtesy of Yokogawa Corporation

Expanded View Fieldbus: Expanded view. Field devices are part of the system. Analog: Limited system view. Does not include diagnostics and other information from field devices mA TAG= LIC-012 VALUE= UNITS= m 3 STATUS= GOOD ALARM= Y/N

Physical Layouts Control Highway Input/Output Boards Host Point to Point Bus with Spurs (or drops) Tree JB Daisy Chain

Values are read from the device Descriptions for variables are obtained from the DD. Digits of precision Engineering Unit Label of the value Gal/Sec Wastewater Flow Device Descriptions (EDDL)

DD File Components Three files per DD file –.sym file –.ffo file –.cff file Single zip file that can be downloaded from FF site EDDL enhancements and ITK 5 will introduce new extension –.ff5 file

Capabilities File Sample Execution Time/32 = time in milliseconds
