Increasing demands on Industrial Network Management and monitoring

Studies prove:

•World market for Industrial Ethernet networks grows continually

•Number of PROFINET nodes rising

•Increasing number of managed devices

•Growing amount of devices with a small size (fewer port count of each device)

This leads to:

•Size of networks will continue to increase

•Complexity within the network will continue to grow

This results in an increasing demand for network management solutions

Network Management

Definition – FCAPS (universal) following ISO standard 10040

The term "network management" usually refers to the administration, the operating technology and the monitoring of IT and telecommunication networks.

The International Organization for Standardization (ISO 10040) defined five pillars of state-of-the-art network management and developed FCAPS, an ISO model.

(F) Fault Management:

•Identify, save, report and solve any error status that occur

(C) Configuration Management:

•Record and manage all components the must be monitored

(A) Accounting Management:

•Record network usage to generate an invoice

(P) Performance Management:

•Gather performance data, maintain statistics and define limit values

(S) Security Management:

•Authenticate users and authorize access and users

SINEC NMS goes beyond FCAPS, offering two essential system elements specifically addressing the industrial network requirements. They complete the NMS offering necessary for the OT environment:

“System Management” and Northbound Interface”

SINEC NMS

SINEC NMS – a new Network Management System

•SINEC NMS is fully webbased network management platform developed to meet today’s and tomorrow’s challenges

•Operators can monitor and manage their industrial network with a single SINEC NMS installation.

•Thanks to the distributed approach of SINEC NMS, the network management system can be dynamically adopted to your specific network requirements.

•SINEC NMS is divided into two levels:

Control:

The control is the central instance in SINEC NMS, which displays the overall condition of the network. It gives the user an overview of the overall network status. Furthermore, the distributed SINEC NMS Operations are centrally managed in the control.

Operation:

The Operations detects the network devices and reads the respective information from the devices. In addition, the SINEC NMS Operations is distributed throughout the network and implement the configuration parameters (policies) from the Control on the devices.

•In addition to using SNMP (Simple Network Management Protocol), it is also possible to directly access SIMATIC controllers (S7-300/S7-400), or access PROFINET participants via “read data record”.

•Detection and fundamental diagnosis of SIMATIC S7-1200 and S7-1500 via SNMP.

•Port statistics: central evaluation of the network utilization of individual ports in the devices: number of received, sent and rejected telegrams.

•A wide range of mechanisms (DCP, ICMP, ARP, SNMP, PROFINET/SIMATIC diagnosis) are used to collect and centrally archive diagnostic data from all network components.

•Diagnostic states are reported as events, assigned to the corresponding devices, and highlighted in the device list and topology. This allows early fault detection.

•The network topology is automatically discovered, displayed and monitored for changes (reference topology).

•Medium type, redundancy and VLANs are graphically displayed.

•Changing topologies (e.g., tool changers) can be monitored without disruptive error messages.

•By structuring the entire network topology into different views, topological hierarchies can be created for the convenient localization.

SINEC NMS – Network Management System – Method and phases

Network scan

•Determination of IP address ranges that are to be searched

•SCAN is done with the following protocols:

•Discovery Configuration Protocol (DCP)

•Internet Control Message Protocol (ICMP)

Filtering possibilities

Monitoring

•Recognition of the IP addresses in the network

•Identification of network participants via

•DCP

•SNMP

•PROFINET

•Reading of device and diagnostical information

•SNMP

•PROFINET read record

•SIMATIC S7 Protocol

•Reading of the network topology with SNMP via LLDP-MIB
