The block 1306 is shown further coupled to the macro function blocks 1340, which is, in turn, shown coupled to the block 1302 through a macro function bus 1310.
which allows programming using function blocks FBs.
View objects 60 are associated with each of the function blocks 50, 51, and 52 and include or group data lists for the function blocks with which they are associated.
Benefits at a glance: Saves time during commissioning: For the first time it is possible to build individual program sections and function blocks, even in the failsafe section, without having to rebuild the entire project.
Likewise, communication between different function blocks must be precisely scheduled on the bus 30 so that the proper data is provided to each function block before that block executes.
As is well known, smart field devices such as, for example, Fieldbus devices, may include one or more logical function blocks that perform control functions or portions of a control function. .
Furthermore, the data publishing times of the different function blocks are scheduled serially so that no two function blocks on a particular segment of the bus 34 publish data at the same time.
Of course, if desired, different function blocks can be intentionally scheduled to execute at the same time and not all function blocks must publish data on the bus if, for example, no other device subscribes to the data produced by a function block. .
In the second block of the tutorial series for the automation system PSS 4000 our experts explain how the PASmulti Editor is organised, how you can also use it to structure program sections programmed in EN/IEC 61131-3 and how to assign function blocks to a resource directly in PASmulti.
As will be understood, to implement any control strategy using function blocks distributed throughout a process control network, the execution of the function blocks must be precisely scheduled with respect to the execution of other function blocks in a particular control loop.

By integrating these custom function blocks with the traditional building blocks into the logic array structure, optimized functions can be added to reduce the area and improve the performance of the target application, which can greatly improve the performance of the eFPGA, especially for embedded applications.
Typically, these control modules are made up of communicatively interconnected function blocks, which are objects in an object oriented programming protocol, which perform functions within the control scheme based on inputs thereto and which provide outputs to other function blocks within the control scheme.

The Fieldbus message specification layer allows the user layer(i.e., the function blocks, objects, etc. of a field device) to communicate across the bus 34 using a standard set of message formats and describes the communication services, message formats, and protocol behaviors required to build messages to be placed onto the communication stack and to be provided to the user layer.
Function blocks may be stored in and executed by the controller 12, which is typically the case when these function blocks are used for, or are associated with, standard 4-20 ma devices and some types of smart field devices, or they may be stored in and implemented by the field devices themselves,

The advanced control loop 36 is illustrated as including an advanced control block 38 having inputs communicatively connected to one or more AI function blocks and outputs communicatively connected to one or more AO function blocks, although the inputs and outputs of the advanced control block 38 may be connected to any other desired function blocks or control elements to receive other types of inputs and to provide other types of control outputs.
outputs of the advanced control block 38 may be connected to any other desired function blocks or control elements to receive other types of inputs and to provide other types of control outputs.
As will be understood, the different function blocks of Fig. 3 may operate together(by communicating over the bus 34) in a number of control loops and the control loops in which the function blocks of the positioner/valve 16, the transmitter 20, and the bridge 30 are located are identified in Fig. 3 by a loop identification block connected to each of these function blocks. .
