Some Kepware Partners…

Terminology OPC = OPen Connectivity through Open Standards SNMP = Simple Network Management Protocol NMS = Network Management System Agent = Software module residing on a managed

device. MIB = Management Information Base Public MIB = Conforms to IETF Standards Private MIB = Unique to Device Manufacturer OID = Object Identifiers Managed & Unmanaged = Device with or

without support for SNMP IETF - Internet Engineering Task Force

Examples of Managed DevicesSwitches Routers Hubs

UPS Bridges Device Servers

Automation Components

Ethernet Components

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.

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 "heartbeat" and "response time" tags provide a standardized and reliable way to monitor all devices in the Ethernet network.

Features 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

Features cont… 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 "polled" such as when a critical system tag goes into an unfavorable state, you can reduce the need for "polling" 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.

Features cont… 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.

Configuration

A Quick demonstration on how to configure the Kepware SNMP OPC Server.

Finish

Configuration1st you must create a Channel

Once you have created a Channel you will then need to create a Device

Configuration cont…If you know the Ethernet devices IP address you can manually enter it into the Wizard to begin your communications.

Configuration cont…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.

Configuration cont…You can selectbetween a few predefined MIBtemplates toimport.

Configuration cont…From the selected device type you will then have the option to select from predefined MIB Modules

Configuration cont…Imported MIBS and OIDs

Once the MIBs have been imported, any supported Client application can begin monitoring the Network.
