Initial value Description, parameter values
NULL Internal input parameter (internal use only!)
FALSE This parameter is for debugging purposes only.
It is set when the F-Device has reset its consecutive
number counter in PROFIsafe communication
FALSE This parameter is for debugging purposes only.
It is a device-based toggle bit indicating a trigger to
increment the virtual consecutive number within the
F-Host
FALSE With input devices this variable indicates if TRUE
that the driver is delivering fail-safe values "0" to the
F-Host program for every input value.
With output devices this variable indicates if TRUE
that every output is set to fail-safe values "0" (default
behavior) or F-Output device specific value controlled
by the "activate_FV" signal
FALSE This variable indicates a request for acknowledgment
prior to the resumption of a safety function. In case
the F-Host driver or F-Device detects a communica-
tion error or F-Device fault, fail-safe values will be
activated. F-Device driver then sets the variable
OA_Req_S (= TRUE) as soon as the fault/error has
been eliminated and operator acknowledgment is
possible. Once the acknowledgment occurred (OA_C
= TRUE) the F-Device driver will reset the request
variable OA_Req_S (= FALSE)
FALSE This parameter is for debugging purposes only.
It is set to TRUE if the F-Device is recognizing a
communication failure, i.e. if the watchdog time in the
F-Device is exceeded
FALSE This parameter is for debugging purposes only.
It is set if the F-Device is recognizing a communica-
tion failure, i.e. if the consecutive number is wrong
(detected via CRC2 error in V2-mode) or the data
integrity is violated (CRC error)
FALSE This parameter is set to TRUE if there is a malfunc-
tion in the F-Device (e.g., under- or overvoltage)
Ä [3].
FALSE This parameter is set to TRUE when F-Device has
new parameter values assigned
FALSE This parameter is for debugging purposes only.
This parameter is set to TRUE if communication fault
(CRC error on F-Host side) occurred.
