2. 2 How do I verify that my plant network is OK? Manually: Watch link lights and traffic indicators… Electronically: Purchase a SNMP management software and a network analyzer package…both designed and oriented to the IT user

3. 3 What can be managed with SNMP? Remote PCs Hubs Switches Routers UPSs Device Servers Printers Any device that includes an SNMP agent….

4. 4 What is SNMP? Simple Network Management Protocol A standard language that allows Network Manager applications to interact with Network Agent applications.

5. 5 What is Network Management Software? Network Management software can: –Poll Network Agents for real-time network status. –Set values in Network Agents. –Provides a graphical user interface to network administrators to show network alarms, network architecture, etc.

6. 6 What is a Network Agent? A Network Agent is an embedded application running in a manageable network device that accumulates real- time information about the performance of the network device it runs on. The data table in a Network agent is called a Management Information Base (MIB).

7. 7 What is in a MIB? Two types of MIBs. Public MIBs include information that would be common to a wide range of network devices. Private MIBs include information that would generally only be found in the specific device that contains the private MIB. The MIBs for an RS2-xx/xx contain more than 1,000 MIB variables.

8. 8 What is in a Public MIB? Public MIB data is governed by a set of standards set by the IETF (Internet Engineering Task Force) Examples of public MIB information include: –Port Link Status. –Incoming traffic per port. –Outgoing traffic per port. –Errors per port

9. 9 What is in a Private MIB? Examples of private MIB information include: –In a UPS Line or Battery Power Battery Strength –In a Hirschmann Industrial Ethernet switch Power Supply Status Redundancy Status –In a Device Server Serial Port Statistics

11. 11 HMI Technology Functional Overview NIC Card PLC Communication Driver HMI Database Historian GUIAlarm Log HMI Server Ethernet Components Plant Control Components HMI software aids in the visualisation of the plant manufacturing process, often using an Ethernet network as the conduit for the distributed PLCs and HMI to connect to each other.

12. 12 Network Management Functional Overview Network Management Server NIC Card SNMP / RMON Communications Drivers Historian GUIAlarm Log Network Management Database Ethernet Components Network Management software aids in the visualisation of an Ethernet network, to centralise the alarming and management of the distributed network devices.

13. 13 Current Technology – Separate “dashboards” NIC Card PLC Communication Driver HMI Database Historian GUIAlarm Log Network Management ServerHMI Server NIC Card SNMP / RMON Communications Drivers Historian GUIAlarm Log Network Management Database Ethernet Components Plant Control Components

14. 14 Disadvantages of current methods If there is no network management, manual component checking is labour intensive and time consuming SNMP management tools are oriented for IT users: complicated and offering many unneeded or seldom needed features. HMI and SNMP management currently have no integrated databases or user interfaces. Reviewing process upsets requires manually matching alarm/event logs. Additional cost for network monitoring: € 5000+ –Network Management PC - € 1500 –SNMP Management Software - € 5000+

15. 15 HiOPC Solution for Industrial Ethernet Networks NIC Card PLC Driver HMI Database Historian GUIAlarm Log HMI Server HiOPC Ethernet Components Plant Control Components HiOPC incorporates real-time Ethernet network status and administration functions into any OPC compliant HMI ! This combines all control system data into one “dashboard”.

16. 16 HiOPC Advantages Makes Ethernet a more dependable platform for industrial networks. Makes devices such as uninterruptible power supplies, switches, hubs, etc. part of the plant monitoring system. Gives the HMI user access to the entire control system.

19. 19 HiOPC Server / Gateway HiOPC Server SNMP OPC

20. 20 HiOPC Editor Tag database must be defined per device You must specify which SNMP variables will be converted to OPC tags

21. 21 Auto-Discovery HiOPC Editor will auto-discover all SNMP-manageable devices and remote segment probes with the click of one button. Great for finding all devices in a network quickly. HiOPC Editor

22. 22 Tag Databases Delivered with pre-built tag databases for Hirschmann products: –MACH 3000 –MICE –RS2-xx/xx –RG2-1TX –Other Hirschmann products New tag databases can be downloaded from the Hirschmann web site. “Full” tag databases and “Light” tag databases

23. 23 MIB Template Generator Creates a custom tag database for any SNMP manageable device. Analyses MIB files from the manufacturers of SNMP manageable devices. HiOPC Editor

24. 24 Network Analyst HiOPC Network Analyst gathers raw SNMP data from your network switches, and computes meaningful network analysis you can display in your OPC client application. Bandwidth Utilisation –Pre-calculated Moving average –Average of last x readings HiOPC Editor

25. 25 Analyst Status Tags Analyst will create status tags for your Ethernet switches. Bandwidth Utilisation thresholds per port and per switch Easily incorporate network health into your HMI. HiOPC Editor

26. 26 User Defined Tags Advanced users have the ability to define their own derived tags. Previous value –Subtract previous value from current value to get new value Delta time –Previous value based on time HiOPC Editor

27. 27 SNMP Traps Support SNMP traps allow network devices to report on exception instead of being polled regularly, reducing network traffic. It is reactive, not proactive. HiOPC v1.0 includes an SNMP Trap configurator to “set” SNMP traps in network devices.

28. 28 HiOPC Communicator / Dataviewer Tools for troubleshooting network devices. Communicator can read and write directly to an SNMP agent. Utilizes what is called MIB Walking. Dataviewer is an OPC client application for reading data from the OPC server.

29. 29 HiOPC Product Portfolio HiOPC Suite Expert –Supports unlimited SNMP network devices and RMON probes –Network Analyst –Derived tags –MIB Template generator –Communicator –Dataviewer HiOPC Suite Basic –Supports unlimited SNMP network devices and RMON probes –Communicator –Dataviewer
