Simple Network Management Protocol (SNMP)

The SNMP is an application–layer protocol defined by the Internet Architecture Board (IAB) in RFC1157 that is used
for exchanging management information between network devices. It is a part of the Transmission Control
Protocol/Internet Protocol (TCP/IP) suite.
The QuickPanel Operator Interface is enabled as an SNMP Agent with the capability to communicate with SNMP

• Provide live values for SNMP Manager's GET/GETNEXT Query calls for HMI Tags

QuickPanel Management Information Base (MIB) Overview
+
The QuickPanel SNMP Agent maintains a MIB that describes the managed device parameters like HMI Tags, alarms, and
+
such. The SNMP Manager uses the MIB to request specific information for the SNMP Agent and translates the information
as needed for the SNMP Managers or Network Management System (NMS).
The MIB is a collection of information for managing network elements. It is a plain text file, self-explanatory, and
prepared based on the Structure of Management Information (SMI), an adapted subset of Abstract Syntax Notation
One (ASN.1)
standard and notation.
Attention
The MIB is comprised of managed objects identified as Object Identifier (Object ID or OID). Each Identifier is unique and
denotes specific characteristics of a managed device. When queried, the return value of each identifier may be
different.
