10 Example — SNMP Communication with OPC

10 Example — SNMP Communication with OPC

Introduction

This section describes how you link network components and nodes with an SNMP agent to a PC station over an OPC SNMP server. You will learn which tools to use to configure a PC station to implement the interfacing of a device with SNMP capability and how make the SNMP variables and SNMP traps available on the OPC interface.

You will find information about the SNMP OPC server on the Web at:

http://www.siemens.com/snmp-opc-server

Initial Situation

If you want to try out the example yourself, you require the following:

Sa PC

Sa network adapter

Sthe SIMATIC NET CD 11/2003 software

Sa device with SNMP capability (for example SIMATIC NET OSM/ESM)

Sa network connection between the OPC SNMP server and the device with SNMP capability

For the PC station, you require a STEP 7 project that was created on a central ES station (not this PC station). This should contain the hardware configuration.
