Logging process data as OPC UA server
In this configuration as the OPC UA server, the CP makes manufacturing or process data
from S7 stations available to a higher-level system.
Higher level systems can, for example, be PC stations with an OPC UA application,
database systems or HMI systems from third-party manufacturers. They must support the
OPC UA client service "Read".
