Signal description:
① The PLC user program receives a new job. The job "prepare tool change" and the job "execute
tool
change" are issued
simultaneously. Txx and M206 have been programmed in one NC block.
② Several intermediate steps are acknowledged. The state of the job remains unchanged. The
positions of the tools
are updated using the transfer steps of the acknowledgments from the tool
management.
③ 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
MD20310: $MC_TOOL_MANAGEMENT_MASK
The response of the interface in DB43xx.DBB1 is affected by the setting in MD20310 bit 10.
This sequence described here corresponds to the presetting of the machine data.
9.4.4 Configuring step tables
Configuring step tables
You can find the transfer-step tables (TM_CTS, DB9900 and TM_VTS, DB9901) and the
acknowledgment-step table (TM_ACK, DB9902) in the Programming Tool under "Libraries"
→ "Special data blocks". The blocks are copied into a project with a double-click.
The structure of the data blocks is permanently fixed.
The blocks are not yet filled with the necessary data. The user must edit them in the
Programming Tool, via the menu "View" → "Data block". The constant tables (TM_CTS,
DB9900 and TM_ACK, DB9902) are configured by writing the initial data block values in the
Programming Tool.
The initial data block values are loaded into the control, along with the PLC user program.
Changed initial values are not activated until the PLC is restarted!
