Diagnostics

All levels of automation in the S7-1500R/H redundant system have integrated diagnostics.
All SIMATIC products have integrated diagnostic functions that you can use to analyze,
localize and log faults and errors efficiently.
System diagnostics is integrated into the firmware of the CPUs and works independently of
the cyclic user program. Faults in the plant are immediately detected and reported on the
display devices.
A uniform display concept visualizes error messages as plain text information over:
● TIA Portal
● HMI devices
● CPU displays
