137. y the FP 3000 Block Overview The FP 3000 consists of a number of blocks A block is a predefined software module that runs on an FP 3000 and acts as a fundamental component of a control system Each block has a number of parameters that can be used to adjust the configuration of that part of the system These are referred to as contained parameters In addition to contained parameters some blocks have I O parameters I O parameters of different blocks can be connected together to establish communications between blocks Each block on an FP 3000 has an associated algorithm There are three types of blocks function blocks transducer blocks and the resource block Function Blocks Function blocks implement the basic control algorithms that make up a control strategy The Fieldbus Foundation has defined a set of ten fundamental or elementary function blocks and a set of nineteen advanced function blocks The function blocks encapsulate a significant part of the control system behavior thereby relieving a host of such tasks The Fieldbus specification defines the parameters of each function block how to make each parameter accessible to host system parameters for configuring function blocks and I O parameters that can communicate to or from other function blocks in the system For example an Analog Input AI function block has parameters to scale a transducer value to engineering units It also has alarm limits that can be configured by a
