Adding and configuring SNMP devices

You can add and configure an SNMP device in Power Operation.

Prerequisites:

  1. Install MIB2CIT. You can download the executable from the Schneider Electric Exchange.
  2. During installation, select Browse > choose C:\Program Files (x86)\Schneider Electric\Power Operation\v[version #] for the Destination Folder > select OK.

NOTE: Do not overwrite newer DLLs during installation.

  • Install the SNMPII driver. You can download the executable from the AVEVA website.

NOTE: To access the SNMPII driver download page, you will require an AVEVA account.

To add an SNMP device in PO:

  1. In Power Operation Studio, go to Topology > IO Devices > Express Wizard.
  2. Add a unique device name to an existing or new IO server.
  3. In the Device Communications Wizard, select SNMP from the tree > select Next.
  4. In the Address field, add the communication address for the SNMP device. Use a valid IP address with the format "aaa.bbb.ccc.ddd community_string". Do not link to an external database as SNMP does not use one.

  5. Select Finish.

To configure an SNMP device in PO:

  1. Located in the PO 2021 bin directory, run the MIB2CIT tool as an administrator.
  2. Configure the project information in the MIB2CIT tool.

  3. Select Config Tags.
  4. Add the MIB file for the device under iso > org > dod > internet > private > enterprises.

  5. Add your desired tags to the device. No tag prefixes are necessary at this point.
  6. Select Close.
  7. Run an SNMP MIB Walk for the device you are using. Confirm the last OID value for use in the next steps.

    8. NOTE: An SNMP MIB Walk tool "walks" the SNMP tree for a target device and pulls the value of each OID from the supported MIBs. Use an MIB Walk tool to discover which MIBs and OIDs are supported on a given device. Search online for a free, open source SNMP Walker, such as Net-SNMP.

  8. In Power Operation Studio, in the Special Opt column, enter the SNMPVAR.DBF file used for the SNMP port.
  9. In DBF editor, open the SNMPVAR.DBF file in the project directory.
  10. Update the OID address for the SNMP values to the values from the devicewalker run.

    11. Example:

    tempSensorValue .1.3.6.1.4.1.52674.500.4.1.1.1.2.x

    humiSensorValue .1.3.6.1.4.1.52674.500.4.1.2.1.2.x

    to

    tempSensorValue .1.3.6.1.4.1.52674.500.4.1.1.1.2.1009011

    humiSensorValue .1.3.6.1.4.1.52674.500.4.1.2.1.2.1009020

  11. Save and close the DBF file.
  12. In Power Operation Studio > Equipment > add an equipment name for the SNMP device.

    13. NOTE: Using the Express Wizard does not add equipment, tag prefixes, or other information.

  13. In Power Operation Studio > Variables > update the tags to fit the IEC61850 tag convention and assign the equipment created in the previous step.
  14. Add an EEHealth tag for the SNMP device.
  15. Compile and run the project.
