Opis:: In the paper a problem of real-time requirements meeting at PLC is presented. Basic parameters associated to real time and factors determining their value were discussed. Real-time reliability indices for PLC and methods of their estimation and experimental testing was also proposed. Results were depicted by examples.

Opis:: A prototype environment called CPDev for programming small distributedsmall-distributed control-and-measurement systems in Structured Text language of IEC 61131-3 standard is presented . The environment is open what means that the code generated by the compiler can be executed on different hardware platforms. However, such universal code must be processed by an interpreter, another words by a virtual machine,an interpreter, another words by- a virtual machine, must process such universal code similarly as programs written in Java. The CPDev environment consists of the compiler, simulator and configurer of hardware resources (i.e. communications). They are developed in C# at MS.NET Framework 2.0 platform. CPDev is open allowing the user to create function blocks and libraries. External interface procedures (drivers) can be written by hardware designers and linked with the universal code. Free selection of data types required by different applications is provided. Virtual machine written in ANSI C is dedicated for a particular processor. So far the machines for AVR, MCS-51 and PC have been developed. Programming a mini-DCS system from LUMEL Zielona Góra has been the first application of CPDev.

Opis:: Design and operation of a compiler and virtual machine, being the essential components of a multiplatform control programming environment, are presented. The compiler translates source programs written in Structured Text language of the IEC 61131-3 standard into executable code in a dedicated intermediate language. The virtual machine, i.e. a specially designed processor implemented in software, is a runtime part of the environment executing the code in real time. Due to memory-to-memory operation principle the machine is able to process various data types defined in the standard. The focus is given on overloading and extensibility of the functions, as well as on uniform invocations of Program Organization Units. By selection of addressing mode, the environment can be deployed on multiple hardware platforms, beginning from 8-bit microcontrollers up to 32/64-bit industrial PCs. Industrial applications are indicated.
