3 Variables 11.033.1 IntroductionNCKContains all the variables such as system data (Y), protection zones (PA), Ggroups (YNCFL) etc. that apply to the entire NCK.Mode groupContains variables such as the status data (S) that apply to the mode group.ChannelContains variables such as the system data (Y), protection zones (PA), globalstatus data (S) etc. that apply to each channel.ToolContains variables such as the tool offset data (TO), general tool data (TD), toolmonitoring data (TS) etc. that apply to the tools on the machine. Each tool areaT is assigned to a channel.AxisContains the setting data and machine data that apply to each axis or spindle.For a description see Section "Axis-specific machine data".Feed / main driveContains machine data and machine data as the service values that apply toeach drive. For a description see Section "Drive machine data".3.1.2 Module typesThe following table provides an overview of the modules for the variables of theNCK and how they are assigned to the individual areas.Only the data modules whose variables can be read or written with directaccess are contained in the list. Data modules whose variables can be definedby the programmer (e.g. global user data) are read by the MMC or PLC usingother mechanisms. The documentation listed below describes the modules towhich these mechanisms are applied:References: /FBO/, Configuring the OP030 Operator Interface,/FB/, P3, "Basic PLC Program" and"OEM-MMC Description of Functions"ModuleAreaA B C H N T VETP 1ETPD 1DIAGN 1FA 1 1FB 1 1FE 1FU 1 1M 1 1NIB 1PA 1 1RP 1© Siemens AG, 2003.
