Reading Out Machine Parameters - HEIDENHAIN TNC 620 User Manual

Programming Q Parameters | String parameters

Reading out machine parameters

With the CFGREAD function, you can read out machine parameters
of the control as numerical values or as strings. The read-out values
are always output in metric units of measure.
In order to read out a machine parameter, you must use the
control's configuration editor to determine the parameter name,
parameter object, and, if they have been assigned, the group name
and index:
Icon Type Meaning
Key Group name of the
machine parameter (if
available)
Entity Parameter object (name
begins with Cfg...)
Attribute Name of the machine
parameter
Index List index of a machine
parameter (if available)
If you are in the configuration editor for the user
parameters, you can change the display of the existing
parameters. In the default setting, the parameters are
displayed with short, explanatory texts.

parameters", page 776
Each time you want to interrogate a machine parameter with the
CFGREAD function, you must first define a QS parameter with
attribute, entity and key.
The following parameters are read in the CFGREAD function's
dialog:
KEY_QS: Group name (key) of the machine parameter
TAG_QS: Object name (entity) of the machine parameter
ATR_QS: Name (attribute) of the machine parameter
IDX: Index of the machine parameter
