<p style="text-align:justify"><span style="font-size:14px"><span style="color:#000000">Communication between robots and their peripherals, for example between the robot-HMI-sensors-PLC, occurs via standard communication protocols. All such protocols have their specific characteristics as well as restrictions. So firstly, the applicable characteristics have to be present, secondly all electronics should have the specific protocol required, also the latency and hardware requirements are all based on the communication protocol being selected. So it is important to have some basic knowledge of these protocols and their capabilities. Some famous protocols used in robotic cells are mentioned below:</span></span></p>
