Existing error
Possible single errors
Max. response time on
error
60
In the presence of an error, it is assumed that a time monitoring responds and triggers the
corresponding error response. Possible causes include errors in the system, incorrect
runtime information in the documentation of the standard system or an extension of the
runtime beyond the value used in the calculation by changing the configuration of the
standard system. The total response time in the error-free case increases by the max-
imum duration of the possible single errors:

Discrepancy error in System SLIO safety SDI. Here, the discrepancy time must also
be taken into account: (TI

SDI and the configured cyclic time of the control must be considered: (TI

Once or permanent interrupted communication between System SLIO safety SDO
and the safety PLC or failure of the safety PLC. Here the Sync Manager monitoring
time of the System SLIO safety SDO and acknowledge time of the System SLIO
safety SDO must be considered: (TO
