Configuring your SNMP MIB file

You must configure your MIB file if you have modified the default SNMP information provided by the meter in order for the MIB file labels to reflect the modified values.

Download the ION MIB file from www.schneider-electric.com.

NOTE: You should only configure the variable name and description. Changing other fields in your MIB file may cause the client software to report problems or return errors when trying to retrieve or view parameters.

The variable name must conform to the following rules:

  • The first character must be a letter.

  • The first character must be lower case.

  • The name must not contain any special characters such as *, ?, &.

  • The name must not contain spaces.

  1. Open your meter’s MIB file in a text editing program (such as Notepad).
  2. Update the variable name and description so they match the meter values connected to the SNMP Mapping module.
  3. Save your meter’s MIB file. Keep the original file extension of .MIB.
This example shows an original and an updated OID entry in an MIB file, where the default meter value of voltage line-to-neutral phase A is modified in the meter’s SNMP Mapping module and is now connected to voltage line-to-neutral phase C.
Original OID entry

Vln_a OBJECT-TYPE

SYNTAX DisplayString (SIZE (0. . 255))

ACCESS read-only

STATUS mandatory

DESCRIPTION “Host Meter Voltage Line A to Neutral Units = V (Volts)” ::= { Schneider Electric 34 }

You must update the variable name and description to match the meter values connected to the SNMP Mapping module:

Value Original Updated
Variable name Vin_a Vin_c
Description “Host Meter Voltage Line A to Neutral Units = V (Volts)” ::= { Schneider Electric 34 } Host Meter Voltage Line C to Neutral Units = V (Volts)” ::= { Schneider Electric 34 }

The SNMP client software reads the original and updated file as follows:

Original Updated

variable name: Vln_a

Description: “SNM1 Input 1 - Voltage (line-to-neutral) phase A”

variable name: Vln_c

Description: “SNM1 Input 1 - Voltage (line-to-neutral) phase C”
