Reading out machine parameters
Use the
CFGREAD
function to read out TNC machine parameters as
numerical values or as strings. The read values are always output in
metric units.
In order to read out a machine parameter, you must use the TNC's
configuration editor to determine the parameter name, parameter
object, and, if they have been assigned, the group name and index:
Icon Type Meaning Example
Key Group name of the
machine parameter (if
available) CH_NC
Entity Parameter object (name
begins with "
Cfg
...")
CfgGeoCycle
Attribute Name of the machine
parameter displaySpindleErr
Index List index of a machine
parameter (if available) [0]
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. To display the actual system names of the
parameters, press the key for the screen layout key
and then the
SHOW SYSTEM NAME
soft key. Follow
the same procedure to return to the standard display.
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
