The aim of this work is to increase the dependability of automation systems through the use of a tool for automatic generating and executing conformance tests. The developed tool calledGungnir uses formalmodels to performits actions,whose standard used is the formalism of Timed Automata (TA). The control systems consists of programmable logic controllers (PLC) and are often developed with Ladder and Function Block Diagram (FBD) languages. The Gugnir s key activity is to verify if the implementation of the control system developed in Ladder is compatible with the specification defined using the ISA 5.2 standard. To do so we used translation tools (from Ladder and ISA 5.2. to TA models), define coverages criteria and heuristics to ensure that the model was well tested
