The SNMP OPC server makes data available for the administration of TCP/IP networks for any OPC client systems.
SNMP (Simple Network Management Protocol) is a protocol that has been specifically designed for administration of TCP/IP networks. The individual nodes in the network (network components or data terminals) are equipped with a so-called SNMP agent that provides information in structured form.
OPC (Openness, Productivity & Collaboration) provides a standardized, open, multi-vendor interface for automation engineering.
The SNMP OPC server supports access to device information over the OPC interface. This means that network visualization, system diagnostics and plant status monitoring can be implemented in any OPC client systems (with OPC clients such as WinCC, WinCC flexible, PCS 7). In addition to simple device diagnostics, detailed information such as redundant network structures or network load distribution can be displayed. This increases the operational safety and improves the availability of the plant.
The device information can be visualized according to individual requirements and can be adapted to the special requirements of the respective customer installation. The information that is made available can also be integrated into the signaling system and alarm log of an HMI/SCADA system for example.
Using the SNMP information, it is possible to expand an existing HMI/SCADA system as far as a customer-specific network management station.
The SNMP OPC server can be operated over the following interfaces:
- CP 1613 A2 (PCI)
- CP 1623 (PCIe)
- CP 1628 (PCIe)1)
- Integral Industrial Ethernet interface of SIMATIC programming devices/PCs or CP 1612 A2
