Each logical device has its own state machine which creates a safe process signal from the input signals and the set parameters.
Page 202 SmartPLC SafeLine AC4S with fieldbus interfaces > States of the input signals 43002 Depending on the type of logical device the following definitions apply:  AS-i slaves Safe AS-i input slaves transmit their input data as unambiguous code sequences. A code sequence consists of 2 half-sequences with each half sequence representing a signal channel.
Page 203 SmartPLC SafeLine AC4S with fieldbus interfaces > Start-up test 43102 If with activated start-up test in the start state both input signals "ChanA" = TRUE and "ChanB" = TRUE, the state machine first goes through a state cycle until both input signals simultaneously take the value FALSE.
Page 204 SmartPLC SafeLine AC4S with fieldbus interfaces > Diagnostic messages 43295 By means of the parameter "DisableLogging" the programmer can control the routing of state messages of the logical devices to the online support centre (OSC). If the parameter is deactivated, all state changes and error events are transmitted to the OSC.
