POSITION CHAINED MAGAZINE
"1" signal: The required tool was found in one of the chained magazines. The signal can be
used to enable the positioning function for the required magazine. Magazine and
locator number as well as the data word address within the magazine table must
be read in data words DW 77 to DW 79.
"0" signal: In all other cases.
SEARCH FOR LOCATION FOR TOOL FROM CHAINED MAGAZINE IN ASSIGNED
MAGAZINE
"1" signal: No suitable exchange tool was found in the assigned magazine for a tool found in
a chained magazine or in a local tool buffer. The signal is used to request the user
to search for a suitable exchange location or empty location for the required tool.
For this purpose, the neutral tool search routine FB 111 and the empty location
routines FB 122 and FB 112 are available (with/without configuring) (for definition
of suitable exchange tools see D 71.6).
"0" signal: If the required tool is loaded in a chained magazine (D 71.8 =1) or in a local tool
buffer (D 71.1=1 and D 71.2=1), an exchange tool has been found in the
assigned magazine (D 71.6=1). The locator number and the data word address of
the exchange tool within the magazine table must be read in data words DW 72
and DW 74 (cf. D 71.6).
