7 Deployment OPC UAPlease note that the simultaneous use of OPC UA and WebVisu on thesame interface is not supported! When attempting to activate them, bothservers are stopped and the diagnostic message 0xE989 or 0xE9AB isoutput.n With an OPC UA project there is the possibility to configure an OPC UA server onyour CPU.n The configuration of an OPC UA project is only possible with the SPEED7 StudioV1.8.6 and up.n Since a OPC UA project is only executable by memory card, a memory card of VIPA(VSD, VSC) must be plugged. Please note that you must always use a VSC card suit-able for your CPU.Ä Chap. 4.16 ‘Deployment storage media - VSD, VSC’ page 111n If the memory card is removed for a short time, the SF LED gets on. This indicatesthat a feature is missing and the OPC UAserver will quit after 72 hours.n When the project is transferred from the SPEED7 Studio, the OPC UA project is auto-matically transferred as TAR file to the inserted memory card.n The OPC UA server must be activated in the CPU.Ä Chap. 8.2 ‘Activate WebVisufunctionality’ page 212n The access is made with an OPC UA client via the ‘Endpoint URL’ of the corre-sponding interface. The ‘Endpoint URL’ can be found on the Device web page of theCPU.Ä Chap. 4.11.1.1.1 ‘Tab: ‘OPC UA’ ’ page 977.1 Generaln OPC - Open Platform Communications– OPC is an interoperability standard for secure and reliable data exchange inindustrial automation.– OPC is platform-independent and ensures a seamless flow of informationbetween devices from different manufacturers.n UA - Unified Architecture– UA specifies security features and data modeling based on a service-orientedarchitecture (SOA).Term definitionsVIPA System SLIO Deployment OPC UAGeneralHB300 | CPU | 013-CCF0R00 | en | 19-30 183
