The ff standard specifies many different function blocks for the construction of control algorithms. Analog and discrete input and output blocks, and a wide variety of control algorithms such as characterizer, splitter, or pid,. These events or function blocks (limit, set reset ff, multiplexer, etc.) are chosen from the function block library
16.4 FF function blocks
You may enter any combination of events up to a total of 128 in your execution list.
Standardized blocks of application logic (e.g., analog input (ai), pid controller (pid), analog output (ao))
These blocks have defined inputs, outputs, algorithms, and. Function blocks make it possible to build a control loop by using fieldbus devices Create interoperation between function blocks by linking an output parameter of one function block to an input parameter of. Configure and commission ff devices out of the abb device library use fieldbus builder for parameterization, diagnostic and simulation use fieldbus builder to configure function blocks within ff.
