Solution for integration of the SNMP computer network management and data pre-processing with SCADA using OPC interface or Web Services It has the following features: - usable for managed and unmanaged devices - implemented OPC specifications:OPC DA 3.0, 2.05,1.0, OPC XML DA, OPC Alarms and Events Version 1.1 and 1.0, OPC UA 1.1 - implemented protocols: SNMPv2c, SNMPv1 - using SNMP commands GET, SET and traps - using ICMP 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 unlimited number of devices with running SNMP agent - pre-processing data using JScripts - support of global JScript variables to enable for example implementation of historical data processing, filtration or other algorithms - on line MIB Browser, which scans SNMP manageable devices for its SNMP variables that correspond to MIB objects - import from csv-files - IP Scanner, which is used for scanning computer network communities in defined IP area - logging of SAEAUT SNMP OPC Server activities to log-files - find functionality for easy finding of items in address space of the OPC server Installation package contains: - SNMP OPC Server configurator with built in JScript editor - runtime application (SNMP OPC Server process) - OPC XML-DA wrapper -OPC UA wraper - source code examples for OPC test clients (written in VB6 and VB.NET) for the communication with SNMP OPC server, using OPC DA3 interface or Web Services
