2.5.6 Programming
Selecting the toolholder
A toolholder is selected with the number m of the toolholder with:
TCARR = m
Access to toolholder data blocks
The following access is possible from the part program:
The current value of the parameter n for the tool holder m is written with the new "value"
with::
$TC_CARRn[m] = value
The parameters of a tool holder m can, as far as the toolholder data set is already defined,
read with:
value = $TC_CARRn[m]
(Value must be a
REAL
variable)
The toolholder dataset number must lie in the range, which is defined by the machine data:
MD18088 $MN_MM_NUM_TOOL_CARRIER (Total number of toolholder datasets that can
be defined)
This number of toolholder data sets, divided by the number of active channels, can be
defined for a channel.
Exception:
If settings, which deviate from the standard, are selected via the machine data:
MD28085 $MC_MM_LINK_TOA_UNIT (Assignment of TO unit to a channel).
Canceling all toolholder data blocks
All values of all toolholder data sets can be deleted from within the part program using one
command.
$TC_CARR1[0] = 0
Values not set by the user are preset to 0.
