PI Interface for SNMP

SNMPv1 and SNMPv2c community strings

  • Last UpdatedOct 03, 2025

For points configured to read a value using SNMPv1 or SNMPv2c, you must specify the correct SNMP community string. For example:

CS=public;

For output points, use the keyword WCS=community-string. For example:

WCS=private;

Caution: Anyone with access to the PI point database has access to these community strings. For tighter security, we recommend putting this information in the password file and using the -ENC command line parameter. This will cause the interface to store the information in the Windows Credential Manager and delete password files when the interface starts.
