Table 28 - Consideration for Recoverable Faults of E-stop Safety Function
Response Time - Occurrence of Nonrecoverable Faults and Failures
Nonrecoverable faults are detected by internal monitoring measures applied to
monitor the safety integrity of the system. These faults are independent of the
logic configuration. Once detected the CR30 forces the safe state within the
internal process cycle time of 45 ms.
