For example:
● Turns of a circular magazine
● Loading/unloading (only for systems without additional buffers such as handling systems,
loaders, etc.)
● Changing manual tools
●
Positioning a magazine
Rules for acknowledgment
If intermediate steps are useful, several rules must be observed during acknowledgment:
The PLC user program must ensure that all acknowledgments are transferred correctly to the
tool management.
● Only one acknowledgment signal at a time may be sent to the tool management.
● Synchronous acknowledgments are permissible only for the pending job
● Only valid transfer-step numbers may be used (1 - 64, 100 - 164). For asynchronous
messages, at least one transfer step must be input for status 201, for status 204 a transfer
step for the new tool must be input.
● Coded positions in the transfer steps may only be used for synchronous acknowledgments
and only with the values 0/1, 0/2 or 0/3.
● No illegal acknowledgment states may be used.
● Magazine positioning with a job may only receive a synchronous acknowledgment (end
acknowledgment). Intermediate positions must be reported to the tool management with
asynchronous messages.
● Acknowledgment signals must be reset by the PLC basic program. After an
acknowledgment bit is set, the user interface may not be changed until the feedback
message in DB41xx/DB43xx DBB100!
● Asynchronous messages with two transfer steps must be acknowledged on the tool change
interface (DB42xx).
