Signal description:
● Acknowledgment OK (DB43xx.DBX100.0): Positive feedback of acknowledgment status.
The acknowledgment of the PLC user program (area DB42xx.DBB0 to DBB3) was
transferred without error to the tool management. This signal is reset after one PLC cycle.
● Acknowledgment error (DB43xx.DBX100.1): Negative feedback of acknowledgment
status.
There is an error in the acknowledgment of the PLC user program (area DB42xx.DBB0 to
DBB3). The cause of the error is displayed in "Error status".
The "acknowledgment error" bit is only set if the acknowledgment from the PLC firmware
is accepted as error free and the tool management detects and signals an error in the
acknowledged tool transfer (for example, when the target location for tool transfer is
occupied).
Errors that are detected directly by the tool management in the NC before an
acknowledgment is sent by the PLC user program, do not result in the setting of bit 100.1.
If an error is present that prevents transfer of the acknowledgment to the tool management
(error status 1 to 7), the error is only output on the interface of the tool management and
not by the NC (no NC alarm!).
If necessary, signal such errors with a user PLC alarm in the PLC user program.
This signal remains pending statically until the error has been acknowledged (set the bit
"Reset acknowledgment error" DB4200.DBX9.0) by the user. The interface in
DB42xx.DBB0 to DBB3 is disabled if bit "acknowledgment error" is pending. Incoming
acknowledgment bits are not evaluated by the PLC firmware and are also cleared when bit
"Reset acknowledgment error" is set.
● Multitool: Location number
Multitool: Location number that the PLC user program entered as active location number
when acknowledging in the acknowledgment interface.
