Signal description:
① The PLC user program receives a new job. The job "prepare tool change" and the job "execute
tool
change"
are
issued
one after the other. Txx and M206 have been programmed in separate
NC blocks. Only the job "prepare tool change" is present in the interface in DB43xx. The job
"execute tool change" is output only after the end acknowledgment for the job for tool prepara‐
tion.
② Bit DB43xx.DBX0.0 (job) is reset with acknowledgment of the "prepare tool change" job. If the
change command (M206) has
already run through the NC main run, the new job is immediately
output at the interface.
③ The "execute tool change" job is acknowledged as a normal job. The end acknowledgment OK
is returned and the bit for the job is simultaneously reset.
The description of the job ("execute tool change" and "prepare tool change") is not reset. Byte
1 of DB43xx is not overwritten until the next job.
Note
MD20270, MD20310:
The
response of the
interface in DB43xx.DBB1 and of NC block processing is affected by the
setting in MD20270: $MC_CUTTING_EDGE_DEFAULT and MD20310:
$MC_TOOL_MANAGEMENT_MASK bit 5, 6, 7, and 8.
This sequence described here corresponds to the presetting of the machine data.
