ABSTRACT:
In this practice the communication between two PLCs is developed by master-slave connec connectio tion n using using this this config configura uratio tion n can send send shares in the master and these will be reflected in the the slav lave and and the the fina finall test est will will perf perfo orm bidirectional connection when actions are send in the slave and these are reflected in the master.
