Diagnostics

Integrated diagnostics across all levels of the automation is incorporated in the SIMATIC S7-
1500 automation system. All SIMATIC products have integrated diagnostic functions which
you can use to analyze and localize faults and errors efficiently. This reduces the
commissioning periods required and minimizes standstill times in production.
A uniform display concept ensures that error messages in the TIA Portal, on the HMI, the
Web server and in the display of the CPU are visualized identically as plain text information.
You can optionally configure machine and plant diagnostics, i.e. the logic of these process
diagnostic messages or monitoring depends directly on the state of the plant and is defined
by you.

Faults in the plant are immediately detected and reported on the display devices, even in
STOP mode. As a result, system diagnostics is always consistent with the actual state of the
plant.
