Adapter transformation:
The adapter transformation is a property of the tool adapter and thus of the complete tool. It
is, therefore, not part of a tool environment, which can be applied to another tool.
By saving the complete data necessary to determine the overall tool length, it is possible to
calculate the effective length of the tool at a later point in time, even if the tool is no longer
active or if the conditions of the environment (e.g., G codes or setting data) have changed.
Similarly, the effective length of different tool can be calculated assuming that it would be
used under the same conditions as the tool, for which the status was saved.
TOOLENV function
Saving a tool environment
The
TOOLENV
function is a predefined subprogram. It must, therefore, be programmed in a
separate block.
Syntax:
Status = TOOLENV(_NAME)
Value/parameter:
Status
INT
0: Function OK
-1: No memory reserved for tool environments:
MD18116 $MN_MM_NUM_TOOL_ENV = 0 (number of tool environments in TO
area).
i.e. the "tool environments" functionality is not available.
-2: No more free memory locations for tool environments available.
-3: Null string illegal as name of a tool environment.
-4: No parameter (name) specified.
_NAME
STRING
Name, under which the current data set is stored.
If a data set of the same name already exists, it is overwritten. In this case, the status is
0.
