The first start of SAEAUT SNMP OPC Server

Configurator Start

After installation of the SAEAUT SNMP OPC Server™ , in case that you picked out this option in the last installation dialog box, configurator will be started with the demo configuration SNMPconf. If not, you can start it from the start menu using SAEAUT SNMP OPC Server -> SAEAUT SNMP OPC Configurator.

Within tree view Address space (Figure 1) you will see preconfigured two devices – UPS_MIB_rfc1628 (for now, we will not work with that) and localhost (there are preconfigured some MIB variables that can be accessible on your computer in case that Windows service the SNMP Service is running ) .
There are also some JScript variables – JScriptVersion, Random_From_10to_20, SystaemLastReinitialisationTime.

Runtime Start

As the configurator contains an OPC client (Monitor View) we can use it to start SNMP OPC Server within runtime application. (If you chose Install as Windows Service during installation it will be already started and OPC client only connect to that.)
Please click on menu-item View -> Monitor View or toolbar-item Monitor View.

After that, Monitor View in the configurator will be open. But, we will probably see none OPC items in that. To be able to see OPC items from a folder under the folder Address space in tree view, we need to click on the folder from that we want to watch OPC items. To watch the JScript variables we can click on Address space folder itself. Now we can see values of the JScript variables in the Monitor View and also their Quality and Time stamps. These variables are not mapped on any MIB variables. They show return values of functions running within JScript engine. Their quality should be good even if SNMP service does not run.

Remark: By installation of the SAEAUT SNMP OPC Server™ also the SNMP Service in Windows is configured and started. However, by next start of your computer it may be will not be running if you have not configured it to start when computer is starting. There can be also problem with configuring SNMP Service by installation in case that you have not installed SNMP Service in advance. In such case please set it by hand as described in white paper or shown in video.
