Deactivation (manual acknowledgment):
SQS is acknowledged after being reached successfully. (Normal request) OR
The violated function is reset. (Violation response)
Deactivation (automatic acknowledgment):
SQS was reached successfully and SQS request ends. (Normal request) OR
The violated function is reset. (Violation response)
Deactivation (violation or fault):
A violation or fault occurs during the reached state of SQS-SS2.
Deactivation (higher priority function is requested)
STO is requested.
Activation:
SQS Reached is activated.
Deactivation:
SQS Reached is deactivated. OR
SOS detects a violation.
The signal indi-
cates if SOS func-
tion is being exe-
cuted.
The SQS signals behave the same way as the corresponding signals in the SS1 and the SS2 functions. For example, SQS Active be-
haves the same way as SS1 Active when the SQS mode is set to SS1. For the behavior in other cases, refer to the figures in 6.2.3.1
Introduction to the SS1 Function and 6.2.4.1 Introduction to the SS2 and SOS Functions.
