systems are one of the most important elements of railway signalization systems
in order to ensure safe transportation. Software design of
the interlocking systems can be performed by different methods such as
automaton method, petri nets. These systems can be implemented by mechanical
components or electronic devices such as Programmable Logic Controllers (PLCs).
In this study, an interlocking system is designed by using automaton method for
a sample railway simulator so that trains can move in a safe manner. In
addition, in order to provide complete automatic operation, another system is
also designed. Then both designed interlocking and automatic operation systems
are implemented in Beckhoff CX1010 PLC and tested on simulator with the help of
human interface that is created for this purpose.
