Overview
OverviewUse Kepware's iSNMP suite to monitor performance and act on network events!
Monitoring Unmanaged Device
Not all Ethernet network devices are SNMP managed. To help monitor any system from within your HMI, 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
Specific Driver FeaturesSpecificLeverage a Proven Server Architecture Kepware purchased all SNMP-related assets of COI Software in September 2007. Kepware has developed a new iSNMP suite that "plugs-in" to Kepware's award winning OPC server architecture. The new drivers in the suite are, the SNMP driver for Managed devices and the Ping driver for Unmanaged devices. The OPC server which houses these drivers is Kepware's field proven KEPServerEX which supports the widest range of connectivity for OPC, DDE, and Native Interfaces. The Ping Device Driver is provided for monitoring your network devices via the ICMP protocol (Ping). The Ping driver was designed specifically for use with 32 bit OPC Server products. The Ping driver provides the ability to monitor the Status of a network device, and the time that it takes for the ICMP message to reach its destination and return a response, the RoundTripTime. Runtime Management of Device Polling All plug-in device drivers including the Ping driver provide communication timeout settings for Connect Timeout, Request Timeout, and an adjustable Retry or Fail After setting. The Ping driver also supports Device Auto-Demotion for Unmanaged devices. Users can adjust Auto-Demotion parameters to allow drivers to temporarily place a device off-scan in the event that it is not responding. This allows the driver to continue to optimize its communications with other available devices on the same channel as well as notify the client application of the event.

Protocol
Communication ProtocolThe Ping driver leverages the Internet Control Message Protocol (ICMP) to determine whether a defined IP or host address is reachable in the IP control network. Use the Ping driver when you need to incorporate device availability status into your automation applications when target devices are not SNMP managed.

Revisions
Ping Driver OPC Driver Revisions| Driver updates below coincide with Server Release V4.280.435.0 (04/30/08) |
| Ping Driver (V4.0.9.0) |
| - New Driver (Suited with SNMP in the iSNMP Suite) |
| Driver updates below coincide with Server Release V4.270.416.0 (09/27/07) |
| All Drivers |
| - Fixed issue where server menu buttons like 'New', 'Open', 'Exit' would become permanently disabled when attempting to perform auto tag generation on a driver that had missing runtime dependencies. - Fixed issue that could occur when multiple items with the same scan rate are read by exception and another item is added/asynchronously read/removed at that same rate. This issue resulted in stale data for those tags read by exception. |
| Driver updates below coincide with Server Release V4.264.401 (06/01/07) |
| All Drivers |
| - Fixed issue in the driver library where it was possible to delete a tag prior to stopping it. This would result in the accessing of invalid memory which could eventually result in an exception that would prevent a channel from processing any tags. |
| Driver updates below coincide with Server Release V4.210.367 (11/17/06) |
| All Drivers |
| - Fixed issue where a rapid sequence of item add, sync read, and item remove requests could result in bad OPC quality for some items included in a block sync read and/or sync read timeouts. - Fixed issue with Unsolicited UDP Mode Ethernet Encapsulation mode, where driver would stop receiving unsolicited messages after sending a message. |
| Driver updates below coincide with Server Release V4.110.270 (3/22/04) |
| All Drivers |
| - Library fix affecting all drivers. |
| Driver updates below coincide with Server Release V4.90.237 (5/10/03) |
