A technique for function block counting

Journal of Systems and Software, 2001
Abstract A systematic approach to the estimation of software size early in the development cycle can pay valuable dividends for project planning and management. This paper reports the successful application of a method which combined function block (FB) counting with structured analysis, used linear regression analysis to convert FB counts to ...

Function Blocks for Fieldbus Diagnostics

2006 IEEE Conference on Emerging Technologies and Factory Automation, 2006
Increasingly field buses are used in a variety of applications as the end users make large investments on fieldbus installations. Therefore the availability of these fieldbuses is of paramount importance in smooth plant operation. Although the fieldbus standards specify the type and format of the diagnostics data, the extent, location and sequence of ...

Integrating UML-RT and Function Block with Function Block Adapters

2012 International Conference on Industrial Control and Electronics Engineering, 2012
The modeling of complex control system is usually based on the UML, thus the distributed control system is generally constructed by function block. This paper studies the modeling element: Function Block Adapter, which responsible for the connection of UML-RT capsule and IEC 61131 function block.

Deductive Fault Simulation with Functional Blocks

IEEE Transactions on Computers, 1978
This paper presents a method of propagating the effects of faults through functional blocks using the deductive (fault list) technique. An extension of the method is shown to be effective for simulating internal faults in functional blocks. The techniques presented here have been used for implementing the functional simulation capability in the Logic ...

Neuromuscular function and block

Current Opinion in Anaesthesiology, 1995
The usual concept of the mode of action of neuromuscular blocking drug fails to explain fully some common clinical observations. A better understanding of the nature of acetylcholine synthesis and release has allowed us to explain some of these findings in terms of a presynaptic action of ...

Standard Function Blocks

2001
This appendix contains a complete overview of all the standard PLC function blocks described by means of examples in Chapter 2. For every standard function block of IEC 61131–3, the following information is given: Graphical declaration (Semantic) description Specification of some function blocks in Structured Text (ST).

Verification of Function Blocks

2014
Formal verification is the field of applying mathematical techniques in order to prove or disprove the correctness of a system against a formally specified behaviour, known as a property. The negative result of the verification process is an execution trace that leads to a state where the system fails to comply with the given specification, known as a ...
