Introducing SAEAUT SNMP OPC Server
Top  Next

Product SAEAUT SNMP OPC Server™ consists of two main applications for Windows operating systems - configurator (with user interface) and runtime application (without user interface) plus a few help applications and software modules. It is sold in three modifications - BASIC, ENHANCED and PROFESSIONAL.

SAEAUT SNMP OPC Server™ is supposed to be used with customer's OPC client applications. However, to gain experience with OPC client usage, some ready made OPC client applications are delivered within SAEAUT SNMP OPC Server™ . There are also source codes for some OPC clients that can be used as templates by development own OPC clients.

The configurator enables to configure address space (sometimes called namespace) and ways of data processing for the runtime application - the SNMP OPC server itself.

Runtime application is used as a communication gateway between SNMP and OPC communication protocols. Some interfaces (OPC DA, AE custom) are provided by the runtime application and some using wrappers (OPC DA automation, OPC XML DA, OPC UA).
There is also application (SAEAUT Web View) enabling reading /writing data using web browser.

Configurator itself contains OPC DA client (Monitor view) that can be used for debugging of integrated applications with SAEAUT SNMP OPC Server™ as well as a few productivity tools enabling fast configuring of big amounts of communication data points. Configuration is mostly saved to mdb database file.

SAEAUT SNMP OPC Server™ usage:

·Integration of monitoring and control of network communication infrastructure and other devices using the SNMP protocol with monitoring and control systems, SCADA and other applications using OPC interfaces.  
·Alarming of devices communicating by SNMP protocol using OPC AE (UA) standard.  
·Monitoring and control of devices with running SNMP agent.  
·Monitoring and evaluation of the availability of unmanaged devices (without SNMP agent).  
·Identification of devices using IP protocol in communication networks.  
·Creating custom applications in JScript to communicate with devices using the SNMP protocol:  
·Recalculation of MIB variables by reading and writing them from / to devices using functions written in JScript  
·Calculation of induced variables, based on MIB variables from devices and other variables and objects provided by JScript engine  
·Store data in databases  
·Sending e-mails  
·Creating custom OPC servers  
·Import of MIB variables from devices connected to manageable devices (with the SNMP agent) and automatic configuration of address space of the OPC server  
·Import of MIB variables from the MIB files to the address space of the OPC server  
·Export and import directories from / into the address space of the OPC server from / to CSV files  
·Providing access to the OPC server address space over Internet/intranet
