Import from MIB and csv files in SAEAUT SNMP OPC Server 2.09

Manual configuration of the address space of SNMP OPC Server can be, for many SNMP variables and many devices, really time consuming.
The SAEAUT SNMP OPC Server provides various methods how to create configurations easy, effective and really fast. At the time of creation of a configuration, you can use single or even combination of the following methods:
- „On-line browsing“,
- import from MIB files (Off-line browsing),
- import from CSV files,
- import from Xml files,
- manual configuration.

On-line browsing

If we have a possibility to connect SNMP devices which we would like to monitor or control then we can use a method called „On-line browsing“ for searching of all available SNMP variables directly from connected devices. Using this simple method, we can transfer on one-click not only one SNMP variable but even entire tree multi-level hierarchical structure to address space of SAEAUT SNMP OPC Server. Advantage of this method is that all obtained SNMP variables are really defined in device and in time of monitoring and controlling of device will be definitely available. Small disadvantage of this method is a limited volume of the information transferred about SNMP variables from the device. It means, we cannot obtain for instance description of a SNMP variable this way. Of course, all important parameters for functionality are available.

Import from MIB file or CSV file

We need very often to prepare a configuration although we have no available SNMP device yet. In this case, we can use one of the following methods: Import from MIB file or Import from CSV file.
A MIB file is a text file which enables to organize SNMP variables in well-known tree structure. The MIB file provides complex information about available SNMP variables (i.e. description of SNMP variable). The MIB file can even include references to other MIB files and then the content of these MIB files can be also included. The number of defined SNMP variables in one MIB file can be large and different for each device type. Therefore, the SAEAUT SNMP OPC Server configurator brings possibility of „Off-line browsing“ for searching of SNMP variables directly from MIB files. Using this simple method, we can transfer not only one SNMP variable but even entire tree multi-level hierarchical structure to address space of SAEAUT SNMP OPC Server on one-click. A small disadvantage of this method is that not all SNMP variables defined in the MIB file have to be available in a specific SNMP device type.
The CSV file is also textual file which structure is very similar to tables. The SNMP variable in the MIB file is presented as one row and its individual parameters (e.g. name or OID) are columns separated by comma or semi-colon. Each SNMP variable starts at the new line (CR+LF) of CSV file. The CSV files are created e.g. by providers of devices or by integrators. Import of SNMP variables from CSV files to SAEAUT SNMP OPC Server is fast and easy (on one-click). As a small disadvantage of this method can be perceived that SNMP variables are not organized in a tree hierarchical structure. But, this feature is not important for functionality because it defines only logic “virtual” organization of the items.

Import from XML file

The SAEAUT SNMP OPC Server provides also another possibility how to configurate address space. The configuration of the SAEAUT SNMP OPC Server is stored in the Microsoft Access MDB file. There is possibility in the configurator tool to export entire configuration to a XML file. This XML file can be modified in an arbitrary xml or text editor and imported to a configuration of SAEAUT SNMP OPC Server.


In the SAEAUT SNMP OPC Server from version 2.09, it is possible to use import CSV and XML files in all distributed versions „Basic“, „Enhanced“ and „Professional“. The „on line browsing“ functionality is available only in versions „Enhanced“ and „Professional“. The import from MIB files called „Off- line browsing“ is available only in version „Professional“.

Details to that can be found hier.
