Solution for integration of the computer network management and data pre-processing with SCADA using OPC interface or Web Services
It has next features:
- implemented OPC specifications:OPC DA 3.0, 2.05,1.0, OPC XML DA, OPC Alarms and Events Version 1.1 and 1.0
- implemented protocols: SNMPv2c, SNMPv1
- using SNMP commands GET, SET and traps
- using ping to manage devices without running SNMP agent and displaying of round trip time as one OPC variable
- tags in address space of the OPC server are defined using MIB object identifier (Object ID), for example .1.3.6.1.4.1.2681.1.2.102; defined Object ID's can be validated by input in OPC configurator
- the possibility to manage max. 10 devices with running SNMP agent
- implementation of MIB Browser, which scans SNMP manageable device for its SNMP variables corresponding to MIB objects, but browsed items can not be added to the OPC address space
- IP Scanner, which is used for scanning computer network communities in defined IP area
Installation package contains:
- SNMP OPC Server configurator
- runtime of SNMP OPC Server implemented as out of process server (exe file)
- OPC XML-DA wrapper
- examples of source codes for OPC test clients written in VB6, VB.NET and C#.NET for communication with SNMP OPC server using OPC DA3 interface or Web Services

The fundamental design goal is that OPC DA Auto interface is intended to work as a 'wrapper' for existing OPC Data Access Custom Interface Servers providing an automation friendly mechanism to the functionality provided by the custom interface. The automation interface provides nearly all of the functionality of the required and optional Interfaces in the OPC Data Access Custom Interface. If the OPC Data Access Custom server supports the interface, the functions and properties at the automation level will work. Automation interfaces generally do not support optional capabilities in the same way that the custom interface does. If the underlying custom interface omits some optional functionality then the corresponding automation functions and properties will exhibit some reasonable default behavior.
Graybox OPC DA Auto Wrapper is the DLL-module, in which all of the needed OLE-objects are implemented. After registering this module, you will be able to use any OPC Data Access Server with almost any OLE enabled programming language (Visual Basic, VBA, etc).
