Communication & interaction
The Simple Network Management Protocol was developed
to be able to monitor and control network elements such
as routers, servers, switches or even Saia PCD® (agents) from
a central station. The SNMP manager software usually runs
on a server. It monitors and controls the SNMP agents. The SNMP
manager reads and sends data from agents using SET and GET
commands. The SNMP agent can also send so-called trap
messages to the SNMP manager unrequested. This allows faults
to be reported immediately, for example.

SNMP GET/SET commands
The Saia PCD® MIB has been specified for Saia PCD® with SNMP
support. It includes all resources which can be requested
and changed using SNMP. It is possible to access all PCD media
(inputs/outputs, register, flag, DBs, etc.). In the MIB file, the
programmer is able to restrict access to selected areas only.
The MIB II standards for managing the TCP/IP functions defined
according to RFC1213 are also supported.

Configuration
Simple activation and configuration of the SNMP functionality in the PG5 device
configurator. Up to 3 SNMP trap receivers can be configured. The data fields
to which the SNMP manager has access are also configured here.
FBoxes
Trap messages with integer or Boolean data or text information can
be conveniently sent to the trap receivers using FBoxes.
SBC MIB File Generator
The MIB file contains pre-defined SNMP strings for accessing the PCD data
(register, flag, DB, etc.) with the SNMP manager.
The MIB files can be generated with project-specific symbol names using the
MIB file generator (available with PG5 V2.1).
