<strong>11</strong>.03 3 Variables3.2 System data3.2.5 Area N, Mod. YNCFL: NCK instruction groupsOEM-MMC: Linkitem/Nck/FunctionGrouping/...All G functions currently configured for the channels are made available forreading by the NCK. They are configured via machine data. Since the Gfunctions are organized in groups, only one of which can be active at a time,this module is organized as a table.There are two columns for each G group. The 1st column lists the number of Gfunctions in a group (/N/YNCFL/Gruppe_NUM), this corresponds to the numberof rows in each subsequent column. This second column contains all the Gfunctions belonging to a group (/N/YNCFL/Gruppe).As a result, the data for a certain G group are calculated via a column offset.The column offset of each variable is:2 * (G group number - 1)The number of G groups is given in the variable "numGCodeGroups" in area N/ module Y. The resultant the maximum column offset of the variables is thus2 * numGCodeGroups.The G functions currently active are listed in area C / module SNCF.FunctionInstruction groupAttention: This variable is called "Gruppe" in the non-Windows MMC and the PLC !- String[16]Multi-line: yes Serial number /N/YNCFL/GroupIDGroupIDNumber of G functions in each G groupAttention: This variable is called "Gruppe_NUM" in the non-Windows MMC and the PLC !- UWordMulti-line: yes 1 1GruppeInstruction groupAttention: This variable is called "Function" in the MMC102 !- String[16]Multi-line: yes Serial number /N/YNCFL/Gruppe_NUMGruppe_NUMNumber of G functions in each G groupAttention: This variable is called "GroupID" in the MMC102 !- UWordMulti-line: yes 1 1© Siemens AG, <strong>2003</strong>.
