DB4300 ... 43xx Signals from tool management [r]
DBWy144
Multitool: Tool distance (FLOAT)
DBWy146
DBWy148 Multitool: Location number (INT)
y [= 0 or 1]: TO unit 1 or TO unit 2
xx: Tool holder
9.3.3 Transfer-step and acknowledgment-step tables
Configurable step tables
There are configurable tables available in the data blocks TM_CTS (DB9900), TM_VTS
(DB9901) and TM_ACK
(DB9902), which are used to describe the tool movement sequences.
Interface signal Name Meaning
DB9900 TM_CTS Constant transfer-step table (configurable)
DB9901 TM_VTS Variable transfer-step table (can be configured and written
to from the PLC user program)
DB9902 TM_ACK Acknowledgment-step table (configurable)
The data blocks DB40xx, 41xx, 42xx and 43xx are system blocks and are created automatically
by the control.
The data blocks DB9900,
DB9901 and DB9902 are made available by the Programming Tool
under Libraries / Special data blocks. The blocks are not yet filled with the necessary data.
The user must copy them into the PLC project and edit them.
Transfer-step tables
The individual tool movements are defined as transfer steps – tool from magazine location x/
y to magazine location m/n. Acknowledgment steps can be defined with these transfer steps.
DB9900 contains permanently configured transfer steps (constant transfer-step table).
DB9901 can be changed by the PLC user program; for example, for acknowledging
intermediate steps such as magazine locations for tool change preparation (variable transfer
step table).
