Abstract

In distributed industrial control systems, functions of control units differ slightly although they seem to be identical. Functions change when hardware is replaced or when the function itself is upgraded. If the standard system is generated by merging the differences and is installed then to each control unit, control units become different with maintenance being carried out in each control unit to fit its operational conditions. Software maintenance therefore becomes very difficult. This paper proposed integrity technique for software maintenance management in distributed industrial control systems. This management has two phases: program-generation for making maintenance easy and program-execution for increasing the reliability of the system. There it contributes to the effectiveness of maintenance and increases the reliability of the total systems
