1.2 Network Management for Industrial Networks

The trend towards larger and larger structures in industrial networks has been

apparent for some time. Vertical integration, in other words the growing together of

industrial networks and office networks, allows transparent access to all data but

also requires integrated diagnostic functions. To meet the new requirements of this

situation, the SIMATIC NET signaling concept using a signaling contact has been

extended to include network management.

1.2.1 Signaling Concept

All active Industrial Ethernet network components have a signaling contact. Using

this digital contact, the network component provides a group signal with which

various statuses can be reported. Using an input module, this signal can then be

passed on to operator control and monitoring systems (for example WinCC) where

it can be visualized. This allows problems in a network to be recognized early and

eliminated. The signaling concept with a signaling contact is a reliable and

adequate monitoring system for small and medium sized networks.

1.2.2 Network Management

For industrial networks extending over large company complexes and linked to

office networks, the signaling concept outlined above is not always suitable for

monitoring the network. Moreover, there are not always suitable I/O cards available

that are capable of reading in these digital signals.

For such networks, SIMATIC NET provides network management functionality

based on SNMP for network monitoring in the OSM/ESM product range.

This allows the new switch modules to be managed, monitored and tested with

every network management tool available on the market, for example, HP Open

View, SunNet Manager or SNMPc from Castle Rock.
