This bit is set if the safety CPU is in one of the two DEBUG states (DEBUG-RUN
or DEBUG-STOP/DEBUG-HALT). This bit is not set in the SAFE-STOP and SAFE-
RUN states.
■
Bit 7: Warning
–
WARN - The set WARN bit (WARNING) indicates a collective warning message
from the safety CPU.
■
Bit 11 ... 8: reserved
■
Bit 12: Error stack
–
EST - The EST (error stack) bit indicates that diagnostic and error messages are
present from the safety operating system of the safety CPU.
This bit is set if there is at least one entry in the error memory of the safety
operating system. These messages can be read and analyzed via iCube Engineer.
As soon as the error memory was read via iCube Engineer and thus cleared, this
bit is automatically reset.
■
Bit 13: reserved
■
Bit 14: POST
–
POST - POWER ON SELF TEST
This bit is set for the duration of the Power-ON-SelbstTest of the safety CPU. After
the self-test is completed, it is reset.
■
Bit 15: Fail safe state
–
FS - Failure State
This bit is set as soon as an error is detected that sets the Safety CPU to the
Fail
Safe state.
⮫
‘Fail safe states’...page 130 In this state, the corresponding further
error code is contained in the diagnostic parameter registers of the safety CPU
(SPLC.DIAG.PARAM_REG and SPLC.DIAG.PARAM_2_REG).
■
The system variable SPLC_CONTROL_COMMAND is used to request the resetting of
diagnostic values from the non-safety project.
■
Via the system variable SPLC_CONTROL_CONFIRM, the safety CPU confirms in the
non-safety project that the diagnostic values were reset.
