Real-time Communication between Automation Studio and PLC based on OPC Technology for control 3-DoF robot

The approach from this work is multidisciplinary, similar with challenges from industrial word which started to implement the new industrial revolution in more and more areas. This paper presents a method of implementing a remote real-time communication, based on Open Platform Communication (OPC) on the Ethernet, for the communication between Automation Studio software solution and a Programmable Logic Computer (PLC) which control a 3-DoF pneumatic robot with a handle gripper. The model of robot is implemented in Automation Studio and this paper uses the benefits of OPC Server in order to connect the simulated system with a PLC. A real PLC is used to implement the supervisory control of the simulated plant. Relation between the physical and the virtual world is an important component of Industry 4.0, represent cyber-physical system.
