SIMATIC NET SNMP OPC server
Description
The SIMATIC NET SNMP OPC server makes available the SNMP information from TCP/IP
networks on the OPC interface with SNMP. Using the SIMATIC NET SNMP OPC server, any
OPC client systems can access diagnostics and parameter data of SNMP-compliant
components, for example the product WinCC.
Non SNMP-compliant components can also be included in the plant visualization using their
IP addresses. Apart from simple device diagnostics, this also allows detailed information
such as the network load distributions of entire TCP/IP networks. With the additional
monitoring of this data, device failures can be detected and localized quickly. This increases
operational safety and improves plant availability. You configure the devices to be monitored
by the SIMATIC NET SNMP OPC server with STEP 7 (alternatively with NCM PC).
