Plug-in Driver Features:
Leverage 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.
The 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
- Internet Control Message Protocol (ICMP)
Any device (IP or Host address) that can communicate via TCP/IP
Unmanaged Device Monitoring
- Building Control Systems
- Device Servers
- HV AC Equipment
- PCs and Servers
- PLCs & Controllers
- Security Systems
- Switches (Unmanaged)
Not all Ethernet network devices are SNMP managed. To help monitor any system from within your HMI, iSNMP 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.
