958 Function Manual, 09/2011, 6FC5397-0BP40-2BA0
PI service: TMCRTO
Function Create tool:
Creating a tool with specification:
• of an identifier, a duplo number, e.g. with:
$TC_TP1[y] = duplo number;
$TC_TP2[y] = "tool identifier";
• optionally a T number, e.g. with:
y = T number
The tool is entered as existing in the tool directory area (TV). The first cutting edge "D1" (with zero contents) is
created for tool offsets in the TO block. "D1" (with zero contents) is also set up for the monitoring data in the TS
block, and simultaneously with zero contents for the OEM cutting edge data in the TUE block - if one is present.
The TD block contains the identifier, duplo number and number of cutting edges (=1) for the T number that is
entered optionally or allocated by the NCK.
If a TU block exists, it will contain the data set for the tool. After execution of the PI, the T number of the tool
created is available in the TV block under TnumWZV.
PI service: TMFDPL
Function: Empty location search for loading
(dependent on parameter assignment):
Location_number_to = -1, Magazine_number_to = -1:
Searches all magazines in the specified area (= channel) for an empty location for the tool specified with a T
number. After execution of the PI, the magazine and locations numbers found during the search are listed in the
configuration block of the channel (component magCMCmdPar1 (magazine number) and magCMCmdPar2
(location number)). Location_number_ID and magazine_number_ID can be set as search criteria or not (= -1).
The PI is acknowledged positively or negatively depending on the search result.
Note
Before and after this PI service, the MMCSEM PI service must be called up with the
associated parameter WVar1 for this PI service. See PI service MMCSEM for more
information.
