9.9.1 Initial settingsMachine dataDefined conditions can be set via machine data for the program operation or certainimplementations of the NC language scope.Initial settingsInitial settings can be programmed in channel-specific machine data for each channel. Theseinitial settings affect, for example, G groups and auxiliary function output.Auxiliary function outputThe timing for output of auxiliary functions can be predefined via machine dataAUXFU_x_SYNC_TYPE (MD22200, 22210, 22220, 22230, 22240, 22250, 22260), (outputtiming for M, S, T, H, F, D, E functions). For more detailed explanations, see Section "H2:Auxiliary function outputs to PLC (Page 377)".G groupsAn initial programming setting can be specified for each of the available G groups usingMD20150 $MC_GCODE_RESET_VALUES (reset state of G groups). This initial setting isautomatically active during program start or in Reset until it is deselected by a G commandfrom the same G group.Via the MD22510 $MC_GCODE_GROUPS_TO_PLC (G codes, which are output to interfaceNCK-PLC after block change / RESET), the output of the G codes to the PLC interface canbe activated.A list of G groups with the associated G functions is available in:References:Programming Manual, FundamentalsBasic configurations of the NC language scope for SINUMERIK solution lineFor SINUMERIK 840D sl, certain basic configurations of the NC language scope can begenerated (configurable) via machine data. The options and functions of the NC languagescope is specially tailored (configured) to the needs of the user.NC language scopeThe way that non-active options and functions should be moved with NC language commandscan be set via the machine data MD10711 $MN_NC_LANGUAGE_CONFIGURATION:0: All available language commands can be programmed. Whether or not the needed functionis activated can only be recognized upon execution.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 arealready recognized at the beginning of the program interpretation and lead to the alarm 12553"option/function is not active."K1: Mode group, channel, program operation, reset response9.9 Program operationBasic FunctionsFunction Manual, 01/2015, 6FC5397-0BP40-5BA2 527
