SIMATIC 545/555/575 System Manual

Troubleshooting CPU Fatal Errors (continued)

The following is a list of the 575 fatal errors:

• Board table, system descriptor table, or application table mismatch —

these tables do not match the power-down configuration on the next

BATTERY GOOD powerup.

• The configuration switches are inconsistent.

• VMEbus error — the CPU receives a bus error while attempting to

access a VMEbus address, and you have not indicated that such errors

should be ignored.

NOTE: Release 3.0 and later provide recovery from VMEbus errors if the

MOVE or XSUB instruction initiates the bus transaction. Refer to the

SIMATIC 545/555/575 Programming Reference User Manual for details.

Table 9-5 describes AUX 29 fatal error codes.
