1. ACCESS TECHNOLOGY GuardPoint Pro OPC Server User Guide The OPC Standard The OPC standard defines common interfaces for the data exchange between devices PLC s and Windows applications OPC The OPC standard has been introduced by a group of major USA companies active in the PLC and visualization market OPC defines an open industry standard interface based on OLE and ActiveX technology that provides interoperability between different field devices automation control and business systems The OPC specification defines a set of interfaces for easy to use objects including methods and properties to manipulate these objects The basic transport layer for OPC is DCOM and therefore a Man Machine Interface MMI or supervisory control and data acquisition SCADA software package can process and collect data from OPC servers that are running on different computers on the network The specification also defines a standard mechanism to access named data items contained in an OPC server Hardware and software developers use the specification to build OPC servers and clients which can exchange information over a network between a wide range of system applications including distributed control systems DCS SCADA systems PLC s distributed I O systems and smart field devices The OPC Data Access Specification version 1 0 was released in August 1996 A corrected version 1 0A appeared in 1997 Version 2 0 followed in late 1998 with major changes in t2. any other application object COM is the core of DCOM ActiveX and OLE What is OLE Object Linking and Embedding is used to provide integration among applications and allows the development of reusable objects that are interoperable between multiple applications It also provides reusable component based software solutions where as the software components can be written in any language www sensoraccess co uk ACCESS TECHNOLOGY What is DCOM The Distributed Component Object Model extends COM to work over a network It is a protocol where remote components appear to be local What is ActiveX ActiveX is an open integrated platform for portable applications and interactive content for the World Wide Web GuardPoint Pro OPC General Information The goal is to integrate GuardPoint Pro into SCADA architecture for management and Access Control through the OPC standard OPC Client can get the following information Communication status of controller Com OK or Comm Error Logical status of all inputs Open Close but depending NO NC Physical status of all relays Open Close e All GuardPoint Pro events Such as o Access Granted Denied Granted with duress code Denied too much trials o Start of Alarm End of Alarm o Technical alarms Such as power off table error o Unknown badge An OPC Client can operate the following operations in GuardPoint Pro e Relay control o Open constant ON o Constant OFF o Open duri
