Diagnostics of the S7-1500R/H redundant system
Diagnostics view in STEP 7 in dependence on the online connection and system states
The diagnostics view for S7-1500R/H redundant systems is partly dependent on:
● Which of the two CPUs the programming device / PC currently has a connection to
● The current system state in the redundant system
The table below provides an overview. The following sections illustrate the diagnostics view
for S7-1500R/H using examples.
