FF Function block Modes

All FF function blocks must support multiple modes of operation, describing how the block should execute its intended function. Several

FF Signal Status

FF function block programming bears a strong resemblance to analog function block circuit design, where specific tasks are divided up

H1 FF Data Link layer

Like so many other industrial data networks, FOUNDATION Fieldbus is an “unswitched” or “broadcast” type of network. This means all

H1 FF Physical layer

Layer 1 of the OSI Reference Model is where we define the “physical” elements of a digital data network. The

Foundation Fieldbus Logics

There is usually some freedom of choice in where various function blocks may be located in a FF segment. Take

FF Function Blocks

Data-processing modules within FF systems are known as function blocks. Sometimes these blocks serve merely to catalogue data, while in

Fieldbus Device Capability

Not all FF devices are equally capable in terms of Data Link (layer 2) functions. The FF standard divides data
