We introduce PLC-Automata as a new class of automata which are tailored to deal with real-time properties of Programmable Logic Controllers (PLCs). These devices are often used in...
Real-Time Logic is a formal notation for reasoning about temporal behaviour. Z is a general purpose specification language, but lacks explicit features for expressing real-time co...
We present a semantics for fault tree analysis, a technique used for the analysis of safety critical systems, in the real-time interval logic Duration Calculus with Liveness and sh...
We present an algorithm for synthesising controllers specified in a subset of the interval temporal logic Duration Calculus [13]. The synthesised controllers are given as PLC-Auto...
