Web browsers are promising candidates for the opc's SOAP-HTTP WS-SC UA XML StackProfile to execute visualization solutions. First tests could demonstrate the applicability of native web browsers without any plugins but the required cryptographic algorithms cause unacceptable response times. The enormous performance improvement of JavaScript engines lets expect an adequate reduction of operating times;this may be strengthen by using an effective HTTP UA-SC UA binary Stack Profile. This paper presents the current development state and first measurements of a opc UA JavaScript Stack which is able to handle opc UA binary encoded and with opc UA SecureConversation secured data.
