Snmp Opc Server from Transcend Automation


Published on

SNMP OPC Server will let your automation system both monitor and manage your automation infrastructure. In addition to monitoring your PLCs and Field Devices, you will be able to communicate with all the pieces that make up your automation network, the backbone of your plant.

  • OPC – In its latest form is referred to as OPen Connectivity through Open Standards. Past definition was Ole for Process Control.SNMP - An application layer protocol that facilitates the exchange of management information between network devices.NMS - is a combination of hardware and software used to monitor and administer a network.Agent – are software modules that reside in managed devices connected to a network that collect and store management information MIB – is a collection of objects in a (virtual) database used to manage devices (such as routers and switches) in a network. MIBs describe the structure of the management data of a device subsystem Public - data conforms to IETF standards per device type Private – data set in a file from manufacturer (OID data unique to this device)OID - identifies a variable that can be read or set via SNMPKepwares SNMP Suite offers connectivity for both Managed and Unmanaged. Unmanaged is done with our Ping driver, included with the SNMP Suite. Unmanaged devices do NOT support SNMP but can respond to HeartBeat polls like communication Status & response Time
  • How does the automation professionalverify the plant network is OK? (with current practices) They either call the IT department or walk around and look for blinking lights and traffic indicators on networked devices.Because Automation controllers are dependant on the performance and reliability of the underlying Ethernet network and components there was a need for a better solution.SNMP OPC Server Gives Automation & Control users access to the entire control system.
  • This section covers some basic configuration steps when using the configuration wizard. Not all steps are included, for a more detailed step by step process please reference the SNMP user manual. 1st Step is to Create a “channel” which is where you will determine which communication driver you would like to use. In this case you will select the SNMP driver.2nd Step is to Create a “device”. This is where you define the Ethernet device you would like to communicate with.

  • SNMP Objects are collections of information with shared traits. A managedObject consists of one or more identifiers.A MIB in a managed device typically consists of many public and private Objects (and resulting object identifiers).OIDS – Object Identifiers - Think of OIDs as items,tags or memory addresses
  • Supported Client technologies include: OPC Data Access: 1.0a, 2.0, 2.05a, 3.0OPC UA:Coming soon to publicDDE Formats:CF_Text, AdvancedDDEOther Formats:FastDDE & Suitelink for Wonderware NIO Interface for iFIX

    8. 8. Using the Kepware SNMP OPC Server software product, automation engineers can easily integrate the monitoring and management of their Ethernet network devices into their OPC client- enabled HMI, Historian, or Alarm package.
    9. 9. Not all Ethernet network devices are SNMP managed. The Ping driver works along side the SNMP driver to help monitor those unmanaged devices. The Ping driver automatically generates OPC tags for each Unmanaged device defined. These quot;heartbeatquot; and quot;response timequot; tags provide a standardized and reliable way to monitor all devices in the Ethernet network.
    10. 10.  Auto Discovery – Save time by using the Auto-Discovery tool to search your Ethernet network for managed network devices  MIB Import – Import MIB files from manageable devices and easily map network device MIB addresses to iSNMP tag names  Network Analyst – Network Analyst gathers raw SNMP data from network devices and continually performs calculations to generate data that can be used, such as bandwidth utilization and network error rate statistics
    11. 11.  SNMP Traps Support - Many SNMP-manageable devices can be configured to send unsolicited data to network management software systems such as SNMP. By configuring an SNMP device to send data without being quot;polledquot; such as when a critical system tag goes into an unfavorable state, you can reduce the need for quot;pollingquot; the network device. SNMP supports receiving SNMP Trap data via Events tags as well as through defined Trap OIDs.  Historical Data Attributes –Historical values are generated by the SNMP driver (not the remote Agent/device) when an OID has valid historical modifiers appended to it.
    12. 12.  Events Tags – A FIFO-based queue to receive Traps/Notifications from previously configured Agents.  Table Offsets – Table access is accomplished by enumerating columns of a table. The SNMP Device driver uses an array- like notation for Table access.  Scan Floor property – SNMP devices are typically scanned at much slower rates than other controls equipment. Scanning an SNMP device too quickly may result in degraded device performance. The Scan Rate Floor has been added to prevent users from inadvertently overloading Agent/devices with read requests in the order of milliseconds.
    13. 13. A Quick demonstration on how to configure the Kepware SNMP OPC Server. Finish
    14. 14. 1st you must create a Channel Once you have created a Channel you will then need to create a Device
    15. 15. If you know the Ethernet devices IP address you can manually enter it into the Wizard to begin your communications.
    16. 16. The Auto Discovery feature allows the user to set a range of IP addresses and then the SNMP Server will scan the network for available devices.
    17. 17. You can select between a few predefined MIB templates to import.
    18. 18. From the selected device type you will then have the option to select from predefined MIB Modules
    19. 19. Imported MIBS and OIDs
    20. 20. Once the MIBs have been imported, any supported Client application can begin monitoring the Network.
