New OPCNetlistener – the Network Watchdog19 October 2005
OPCNetlistener checks SNMP variables or ICMP as OPC items, offering a simple yet elegant solution to display information on errors or the status of active TCP/IP network components. OPC-Netlistener informs immediately if a network component is overloaded or failing. The diagnostics provided can be displayed in any OPC type visualization.
The Netlistener OPC-Server is a convenient network monitoring tool. It provides status data on network devices through ICMP, SNMP. OPC-Netlistener provides information on the state of the network, detecting Ethernet errors early, resulting in a transparent Ethernet. Automation Process Engineers will welcome the easy integration into HMI (Human Machine Interface) through OPC and the option to program individual network management applications in SCADA (Supervisory Control and Data Acquisition), DCS, PLC (Programmable Logic Controller) and similar systems. Developer Sven Ilius says: “Automation Process Engineers will find this new software helpful in supervising various network loads and applications.”
With OPCNetlistener the server sends ICMP (ping) or SNMP-requests to the supervising hosts, and presents these as an OPC-item. Or it supervises cyclical processes on the host to check for program errors. The server can be tested through Matrikon© - OPC - Explorer and can be used with any OPC-Client.
The server allows supervising device processes (watchdog function) and provides the operator with the CPU load data as an OPC variable. In addition it shows the CPU load of the host computer.
A free trial version of OPC-Netlistener can be downloaded from http://automation.wallpaper-calendar.com/. The full version key for the network watchdog “OPC-Netlistener” costs only $150.- / €124.- / £90.-.

Information about OPC
OPC (OLE for Process Control) shows an initiative to standardize the data exchange in automation technology. Due to this technology data can be exchanged between automation systems with no need for drivers. This allows the use of different visualization systems for any process. For example, it makes it possible to easily access process data at the office through Microsoft Office.
