Diagnostics Overview for SIMATIC S7-1200 and S7-1500
https://support.industry.siemens.com/cs/document/109752283/
Diagnostics reduces downtimes and thus increases the productivity of the machine. Diagnostics supports the entire lifecycle of a machine, from planning to operation and maintenance. Diagnostics essentially involves the diagnosis of all system components, the monitoring of process sequences and the diagnosis of program errors.
System diagnostics
In the SIMATIC environment, the term "system diagnostics" is used to describe the diagnostics of devices and modules. The faults can be displayed in plain text. This enables maintenance to locate and rectify the error more quickly.
Faulty devices and modules can be diagnosed with the user program. Thus responses to diagnostic messages can also be programmed in the user program and, as a result, undesired machine behavior can be prevented.

Machine and system diagnostics.
Many faults are operating in a process of mechanical or electrical components.
With an efficient plant-specific diagnosis of faults and information on the location of the fault, the cause of the fault and troubleshooting information, faults can be identified and rectified.
The error bits of the machine and system diagnostics can be queried in the user program, in order to stop the machine in the event of certain faults, for example.

Diagnostics of program errors
Programming errors occur during commissioning, but also during operation.
The possibilities for the analysis programs, errors in the program can be quickly localized and eliminated.

Diagnostics in User Program with S7-1500
https://support.industry.siemens.com/cs/document/98210758/diagnostics-in-user-program-with-s7-1500
The diagnostics of devices, modules and networks play an ever-increasing role in automation technology.
By diagnosing with a user program, faulty modules can be detected. This enables you to also program responses to diagnostic messages.
All SIMATIC products have integrated diagnostic functions that allow you to detect and clear faults. The components automatically report a fault during operation and provide additional detailed information. Plant-wide diagnostics can minimize unscheduled downtimes.

This application example describes how to monitor a PROFINET IO system and a PROFIBUS DP master system with different devices in the user program. The devices are connected to an S7-1500 controller via PROFINET IO / PROFIBUS DP. The devices detect faults on their modules and send the diagnostic data to the assigned controller. The controller evaluates this diagnostic information with the diagnostic instructions in the user program and saves it to a global data block. The operator panel graphically displays the evaluated diagnostic information in one view per IO system or in a device view.

It considers the following states:

System Diagnostics with S7-1500 and TIA Portal
https://support.industry.siemens.com/cs/document/68011497/
When a system error occurs, hardware components and devices of other manufacturers can trigger a system reaction. The hardware components provide information on the system error that has occurred. For S7-1500 PLCs, the system diagnostics provides a convenient way to evaluate this diagnostic information and display it in the form of alarms.

The system diagnostics are integrated in the firmware of the CPU S7-1500 and work independently from cyclic user programs. Therefore it is also available in the CPU operating mode STOP. Any faults are detected immediately and reported to the higher-level HMI device, the web server, the display of the CPU S7-1500, the LED displays in the module concerned and in the TIA Portal even in the operating mode STOP. Therefore, the system diagnostics are always synchronous with the actual system status.

This application describes:
the various display possibilities of the System Diagnostics
how you can configure the System Diagnostics quickly and easily, using a few examples
the System Diagnostics with the user program.
The following picture shows the most important components of the solution with an S7-1500.

The device detects a fault and sends diagnostic data to the assigned CPU.
The CPU informs the connected display media. The display of the system diagnostics is refreshed.
Advantages
Integrated System Diagnostics
The integrated System Diagnostics ensure full transparency of the system status. The system diagnostics are generated automatically.
Uniform display concept
The system diagnostics information is displayed as a uniform clear text information in the CPU display, TIA Portal, HMI and the web server itself for messages of the drives.
Channel granular display concept
In case of failure, the respective channel can be detected and classified quickly.
