The Open Charge Point Protocol (OCPP) is added to the IoT product portfolio based on the WebSocket protocol. OCPP standardizes the communication between charging stations for electric vehicles and the associated central management systems (CSMS). OCPP versions 1.6 and 2.0.1 are used here on account of their market relevance. The OCPP product addresses two use cases: In the first use case, TwinCAT is used as a control for a charging station in connection with the new EL6761 terminal before being connected to a CSMS as an OCPP client. The second use case, on the other hand, focuses on integrating other charging stations via the OCPP. Here, TwinCAT represents part of the CSMS and is capable of providing local load management for charging station networks, among other applications. Also in this case, TwinCAT may still be connected to a remote CSMS in parallel to facilitate authentication processes, billing mechanisms, and much more besides.
