ABSTRACT
Every FF ¦eld device is capable of executing those functionalities encapsulated in function blocks that are the basic elements for programming FF applications and executing control and automation algorithms, such as PID control, arithmetic operations, analog and digital input/output, etc. Another major characteristic of the FF protocol is its advanced diagnostic capability, which de¦nes not only the health of the device but now also in a standard format that can be easily integrated into asset-management systems.
