Diagnostics mechanisms of PROFINET IO

Totally Integrated Diagnostics Concept
All SIMATIC products have integrated diagnostics functions that they can use to detect and
remedy faults. The components automatically flag a potential fault in the operation and
provide detailed information.
Each individual error or several errors occurring concurrently are transferred from the IO
device to the IO controller. If you require the full status of the IO device including any
pending errors, you can also read the status directly from the IO device.
The following sections provide basic information on using diagnostics via PROFINET IO.
You can find a detailed description of the system diagnostics for S7-1500, ET 200MP,
ET 200SP and ET 200AL in the Diagnostics
