Moby/PLC

 

1 Introduction

Moby/PLC is a design tool for distributed real-time control programs running on programmable logic controllers (PLC). First, a system is modelled as a network of PLC-Automata, a graphical programming language with real-time extensions. Moby/PLC simplifies the design of large networks of PLC-Automata by a concept of hierarchy and a library of components. It is possible to simulate an arbitrary subnet of a design either in an interactive or in a background mode. To increase the reliability it is even possible to use real-time model-checking tools to verify formally whether a chosen subnet fulfills a given (real-time) property. Finally, control programs for the involved PLCs are generated automatically from the system specification.
