Programmable logic controllers (PLCs) are the core element of industrial\nplants in todays deployments. They read sensor values, execute control\nalgorithms, and write output values. Furthermore, industrial plants have\nlifetimes of one or more decades. Thus, in a realistic Industry 4.0 scenario,\nthese devices have to be integrated in novel systems. In order to apply\nadvanced concepts and technologies, such as computation offloading, which\nrequires data exchange between PLCs and edge cloud, we investigate open\ncommunication interfaces of two typical PLCs of Siemens S7 series. Hence, each\nof the interfaces is analyzed based on plug & play capability, if metadata is\nprovided, protocol efficiency, and performance. For the latter, the smallest\npossible update time for each of the interfaces will be measured.\n
