8.1 Diagnostics / correction of errors

Incorrect operation, faulty wiring, or an incorrect hardware configuration can cause errors. The CPU 312C displays such errors with the group error LED SF following a memory reset. For information on how to analyze errors and mes- sages, refer to the “S7-300, CPU 31xC and CPU 31x: Installation” operating instructions. This manual is included in the SIMATIC Manual Collection, which is enclosed in the S7-300 starter kit.

The PC Adapter USB uses LEDs to indicate error states. To diagnose these errors, refer to the electronic “PC Adapter USB” Manual. You can find this man- ual on the installation CD for the PC Adapter USB.
