F_FB_KTP_Mobile
Inputs
Parameter
Data type Description
Interconnection
QBAD
Bool
QBAD indicates whether there is an F-I/O
communication fault.
F-I/O DB:
DBx2.1 = QBAD
ACK_REQ
Bool
Acknowledgement required
After a communication error, the fail-safe
system sets QBAD = 1 and ACK_REQ = 0.
ACK_REQ = 1 indicates that the PROFIsafe
message frames are being exchanged again.
F-I/O DB:
DBx2.2 = ACK_REQ
RESET
Bool
This input resets the status of the
F_FB_KTP_Mobile to its "original state".
The input is only evaluated if Q_BAD = 1.
Setting the input RESET is necessary if the
HMI device cannot return itself to a defined
state, for example when an internal error
occurs.
This input responds to a rising edge.
Must be specifically
interconnected for
plant.
The safety program
must ensure that
automatic restart of the
plant is not possible
after RESET is set. The
operator must strictly
ensure that he
executes a separate
operator action to
commence the restart.
ACK_ERR
Bool
Communication errors may not be
acknowledged automatically.
This input is set to have the F-CPU to
acknowledge a communication error during
ongoing PROFIsafe communication.
This input responds to a rising edge.
Must be specifically
interconnected for
plant.
MP_DATA
Int
User data of the F-process image input
PII:
Int 1 = MP_DATA
