Problems solved by technology

Traditional intermediate representations of data are not defined in a sufficiently rigorous manner to define the semantics of the data
The fact that conventional intermediate representations cannot help overcome existing decompilation problems

Embodiment Construction

[0112] Referring to FIG. 1 , a general programmable control system for controlling a process of the so-called solid state interlock type is schematically shown by means of a block diagram. The control system is formed by a hardware structure comprising one or more general actuators 1 for performing the control functions of the process. For example, in an apparatus for feeding liquids into a user device in a controlled manner, the fluids may be mixed in specific ratios and the actuators may include regulating valves. Said valves may be actuated remotely by means of an actuation signal or command 101, provided with an actuation unit, and may have means for indicating their operating state 201, for example between a maximum open position and a closed position allowed for Different opening positions of the valve.

[0113] The general equipment of the control system may also comprise signaling means for visually indicating certain states. Furthermore, the signal unit 2 has drive ...

Abstract

Method for preparing and checking software means to be executed by programmable control devices or plants for carrying out processes, in which: a) a programming language for expressing the software means is provided, which language is based on an abstract syntax, particularly an object oriented syntax; b) the said programming language being generated from both the source code language and the object code language; c) expressing the control program in the said programming language; d) deriving the source code format and / or the object code format of the control program by translation of the said control program expressed in the language based on the abstract syntax into the language of the source code format and / or of the object code format of the abstract syntax.

Description

technical field [0001] The present invention relates to a method for preparing and checking application data to be executed by a data-driven control system, more particularly to a solid-state interlock for a railway signaling network, and wherein: [0002] The network comprises at least one central interlocking processing unit and one or more remote or peripheral operating units, such as one or more actuators for performing mechanical tasks, and / or one or more One or more signal units, and / or one or more sensors for measuring physical and / or chemical parameters; [0003] The network further comprises one or more data communication lines connecting each of the one or more remote or peripheral operating units to a central interlocking processing unit for sending so-called incoming data telegrams to the central an interlocking processing unit, and for receiving output messages or command messages generated by the central interlocking processing unit; [0004] The central proces...
