Example: Diagnostics view in the project tree and in the device view and network view
An example of the diagnostics view for a S7-1500R/H system is shown below.
The sample configuration consists of two CPUs S7-1517H-3 PN and one interface module
IM 155-6 PN HF as PROFINET IO device. PLC_1 is the primary CPU (in RUN operating
state). PLC_2 is the backup CPU (in STOP operating state). The hardware configuration and
the user program were loaded in the primary CPU.
The system is connected online via PLC_1 (primary CPU) and is in RUN-Solo system state.
