Structure of the tool management

Function structure
The software components of the control have the following tasks in the tool management:
● HMI:
● NCK:
● PLC:
PLC user program
The PLC user program executes the tool management jobs and acknowledges all position
changes of the tools (and magazines). The monitoring and prevention of collisions is the task
of the PLC user program alone, for example:
● Multiple spindles are using the same magazine.
● The paths of simultaneous jobs cross.
● As long as a large tool is located in the shifter, the chain must not be moved.

– Tool data display, input/output
– Magazine data display, input/output
– Load/Unload relocation dialog
The tool management administrates the magazine locations. These locations might be
empty, loaded with tools or assigned to oversized tools in adjacent locations. Empty
locations can be loaded with other tools. The tool management provides the machine
manufacturer with optimized management of tools and magazine locations. Magazine
management provides extended functions such as load, unload or position tools. It also
includes searches for tools, magazine locations and search strategies for replacement
tools.
For the tool monitoring functions, while the active monitoring is running, tools are disabled
and no longer used. To continue machining, an equivalent tool (duplo tool) that is not
disabled is used, if available.
