2.4 Tool change configuration
With the string configuration in the tool change configuration,
you can commission modules on the CPI extension connec-
tion
without a new configuration . In the tool change configur-
ation, pressing the SAVE button is not necessary.
The tool change configuration is useful if various CPI string
extensions are connected in turn to the CPV Direct during
operation.
Note
In the tool change configuration, the system does not
check which modules are actually connected. After modifi-
cation to the string assignment, evaluation of input signals
may appear to be incorrect if inputs, which are no longer in
the new string assignment, are read. The current CP string
extension can be ascertained via Object 3100.2-5.
After modification to the string assignment (e.g. with fewer
modules): Make sure that the controller processes only the
addresses of the modules actually connected to the CP
string. The same applies for outputs.
Addressing and function With the tool change configuration, the maximum possible
32 inputs and 32 outputs will be assigned in the CPI string
extension, irrespective of whether these are used or not. The
addresses are assigned without gaps, module after module
in ascending sequence. Please take this into account when
programming the controller.
