MIB Browser is implemented as a new dialog window. It contains controls filled with Name, IP address and Community values of device going to be browsed. There is an edit control containing the Default object ID from which the device is started to be browsed. Its value can be changed according to the user needs. By clicking the Load MIB (On-Line) button, user invokes browsing of device from the specified Default Object ID.

Browsed MIB Objects are logically structured and displayed in a tree view. They contain object ID (OID), value and data type (Syntax) associated with each of them.
|
| Figure C: MIB Browser (On-Line) shows all available SNMP variables from localhost computer.
|
The items listed in the tree view can be added into the configuration of SAEAUT SNMP OPC Server™ keeping the level structure specified by browsing. SAEAUT SNMP OPC Server™ takes over the Name of the variable, its object ID (OID) and data type (Syntax).
Because Access rights of particular variables are not SNMP attributes receivable from the device, these rights are defaultly set to Read-Only. It is user's task to change these access rights and user responsibility for misusing them. Because of, the Name of the variable read from device can contain dot characters and such names are not allowed to be used in SAEAUT SNMP OPC Server™ , when transfering in the database all the dots characters in the names are replaced by underline characters.
User can add specified items into SAEAUT SNMP OPC Server™ configuration one by one or a group of them at once by selecting wished item or folder in the tree view and clicking Tranfer object(s) to configuration button. When choosing the folder, all the subfolders and items are added into configurator database keeping the structure created by browsing.
