NC language scope
The way that non-active options and functions should be moved with NC language
commands can be set via the machine data 10711
$MN_NC_LANGUAGE_CONFIGURATION:
0: All available language commands can be programmed. Whether or not the needed
function is activated can only be recognized upon execution. This corresponds to the default
setting for previous controls such as SINUMERIK 810D/840D and 840Di powerline.
If only certain options are enabled and not all operations are available:
1: All the language commands are known. Language commands for non-enabled options are
already recognized at the beginning of the program interpretation and lead to the alarm
12553 "option/function is not active."
2: Only those language commands are known, which correspond to the current scope of
enabled options of the NCK software. All commands for non-enabled options are not
recognized and trigger the alarm 12550 "Name not defined or option/function not available".
This setting is intended especially for SINUMERIK 802D sl, but can also be used for others.
Note
Option-free functions also have the status "enable option"
If only certain functions activated are:
3: All the language commands are known. Non-activated functions are already recognized at
the beginning of the program interpretation and result in the alarm 12553 "Option/function is
not active". For example, if the option date is set for the cylinder coat transformation, but the
transformation is not activated in machine data MD24100 $MC_TRAOF_TYPE_1, then the
programming of TRACYL triggers the alarm 12553.
4: Only those NC language commands are known, which correspond to the current scope of
active functions of the NCK software. All commands for non-active functions are not
recognized and trigger the alarm 12550 "Name not defined or option/function not available".
Whether the command in question is generally unavailable in the Siemens NC language or
whether this is true only on the corresponding system cannot be distinguished in this
scenario.
Whether the current NC language scope of enabled options and active functions is also truly
programmable can be checked using the STRINGIS program command, see example.
