Online & diagnostics for the redundant system
"Online access":
For the S7-1500R/H redundant system, it is displayed whether an online connection exists
between the programming device/PC and a CPU. The additional note "Online (via Primary
CPU)" or "Online (via Backup CPU)" indicates which role the "Online" connected CPU has.
If you enable "Receive alarms", you receive asynchronous alarms of diagnostics events from
the CPU with online connection. The display corresponds to the representation for standard
CPUs.
