S7 OPC Redundancy for Industrial Ethernet
2
■
Function
S7 OPC Redundancy enables the setup of redundant OPC UA
servers, thus ensuring plant access for the operator control and
monitoring systems.
This means, for example, that the information synchronization
between two SIMATIC NET S7 OPC servers via the S7 OPC
Redundancy software package is guaranteed. This is handled
transparently for the OPC Client application so that in the event
of a fault, the redundant OPC server takes over the tasks from
the failed OPC server system.
Data exchange between the OPC clients and the OPC servers
takes place via the standardized OPC UA communication.
Communication with the SIMATIC S7 controller takes place using
the S7 protocol. This is ensured by the software products
SIMATIC NET SOFTNET or HARDNET-S7 for Industrial Ethernet
that are necessary as the basis for SIMATIC NET IE S7 OPC
Redundancy.
The S7 OPC Redundancy software package supports:
•
High availability;
Failure of one OPC UA server results in immediate use of the
other OPC
UA server, and continuation of the existing OPC
UA
client connection. The basis for this is the OPC UA synchroni-
zation that ensures synchronization of the necessary client
information.
•
Load compensation;
Even distribution of OPC clients among the available OPC
servers
Configuration
A configuration tool is included in the scope of delivery of the
software package.
