Monitoring and diagnostics of networks

Monitoring and diagnostics of networks

SIMATIC PCS 7 communicates with the subordinate com- ponents of Totally Integrated Automation via Industrial Ethernet and PROFIBUS and uses the network components and communications processors (CPs) of SIMATIC NET. In addition to reliable communications, these also offer the facility for network diagnostics during runtime.

Monitoring of PROFINET/Industrial Ethernet

Network components

Network components are SCALANCE X (Industrial Ethernet switches), SCALANCE W (Industrial WLAN), and SCALANCE S (Industrial Security).

SCALANCE X-200 managed

Universally applicable, from machine-level applications to networked plant sections. Configuration and remote diag- nostics are integrated in the STEP 7 engineering tool. This in- creases plant availability. Devices with a high degree of protec- tion permit a cabinet-free construction. Appropriate switches (SCALANCE X-200IRT) are also available for use in plant sec- tion networks with hard real-time demands and maximum availability.

SCALANCE X-300 managed

Networking of subsystems/plant sections, as well as for con- necting to the enterprise network. The SCALANCE X-300 ma- naged product line combines the firmware functionality of SCALANCE X-400 with the compact design of SCALANCE X-

200.The SCALANCE X-300 switches thus offer expanded ma- nagement features and firmware functionality in comparison with the SCALANCE X-200 switches. Moreover, electrical and optical Gigabit Ethernet ports are available, as well the XR-300 Rack Switches as versions in 19-inch design.

SCALANCE X-400 managed (Layer 3)

For use in high-performance plant networks (e.g. with high- speed redundancy). Due to the modular design, the switches can be adapted to the task at hand. Due to the support of IT standards (e.g. VLAN, IGMP, RSTP), the seamless integration of automation networks into existing office networks is possi- ble. Routing functions on Layer 3 support communication bet- ween different IP subnets.

SCALANCE W

Thanks to wireless communication, an even higher level of plant flexibility can be achieved, maintenance work is simpli- fied, and service times and downtimes are reduced. The IWLAN solution from Siemens Industry makes these advanta- ges available through a coordinated portfolio of WLAN equip- ment for industrial use, even for fail-safe communication in the context of operator and machine safety. This includes IWLAN access points and client modules (SCALANCE W),

wireless connections for PROFIBUS and distributed I/Os, mobi- le operator panels, planning software, and extensive accesso- ries.

SCALANCE S

The SCALANCE S security modules enable logging of access data in one log file (syslog protocol). These data show how, when, and by whom the network has been accessed. Attack attempts can be detected early and appropriate preventive measures taken.

Network management

The integrated network management with the standard SNMP (Simple Network Management Protocol) in SCALANCE X and W provides information for device diagnostics.

The network management products SINEMA E (SIMATIC Net- work Manager Engineering), SINEMA Server (Management), and the SNMP OPC server provide support in the planning and simulation or monitoring and diagnosis of wireless and wired networks in the industrial environment.

SINEMA Server is specifically used in larger networks and for extensive network management. The SNMP OPC server is used exclusively for the processing of SNMP message frames and their transfer to be represented in other systems.

SINEMA Server network management

The SINEMA Server (Simatic Network Manager) network ma- nagement software diagnoses and visualizes Ethernet net- works. It continuously logs network activities using various protocols such as SNMP, DCP, and LLDP and makes them available to users and other systems on the network, e.g. HMI software such as WinCC, for evaluation and further proces- sing. Devices, their properties and their topology are recog- nized, and network statistics are compiled by means of auto- discovery.
