SmartPLC SafeLine AC4S with fieldbus interfaces
The following table shows the meaning of the individual components of the AC4S:
Component Description
T(sensor) Response time of the safety sensor
T(input) Response time of the safety input device
T(comin) Response time of the input communication
channel (as from terminal)
T(splc) Processing time of the fail-safe PLC
T(comout) Response time of the output communication
channel (up to terminal)
T(output) Response time of the output variable unit
T(actuator) Reaction time of the actuator
The process safety time is extended by 1 PLC cycle if the safe AS-i input slave or the safe
local input channels are configured in CODESYS by means of the following logical devices:

SF_IN_ASi_dependent_filter_nshutdown

SF_IN_local_dependent_filter_nshutdown
