2.10.3 Delete tool environment
DELTOOLENV function
This function can be used to delete sets of data used to describe tool environments. Deletion
means that the set of data stored under a particular name can no longer be accessed (an
access attempt triggers an alarm).
The DELTOOLENV function is a predefined subprogram.
It must, therefore, be programmed in a separate block.
Syntax:
There are two call formats:
Status = DELTOOLENV()
Status = DELTOOLENV(_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: A tool environment with the specified name does not exist.
_NAME
STRING
Name of data set to be deleted
The first call format deletes all data sets.
The second call format deletes the data set with the specified name.
Data sets can only be deleted using the DELTOOLENV command, by an INITIAL.INI
download or by a cold start (NCK powerup with default machine data). There are no further
automatic deletion operations (e.g., on RESET).
