11.03 2 Machine and Setting Data2.1 Explanatory notes on the machine and setting data6 or 16: Keyswitch position 17 or 17: Keyswitch position 0.Complete protection:The numbers within the range from 0 to 7 determine that assigned data in theNC program and in the MDA mode cannot be overwritten or read.Conditional protection:The numbers within the range from 10 to 17 determine only for user data(GUD) that assigned data in the NC program and in the MDA mode can beoverwritten or read.The operation and display are always protected for both protection levels.The interlock for protection levels 0 to 3 can be canceled by setting a password,the interlocks 4 to 7 can be canceled via keyswitch position.The user has only access to information which corresponds to the currentprotection level and to lower protection levels. The machine data are assignedvarying protection levels as standard function.The user can change the priority of the protection levels. In the machine data,only low priority protection levels can be specified, but higher priority levels canbe specified in the setting data.The following passwords are used for redefinition by the user:APR (Access protection read) indicate read authorizationAPW (Access protection write) indicate write authorization.After the password, you will find the protection level to be set in each case asnumber.Example 1: Change rights for individual MDs%_N_SGUD_DEF File for global variables;$PATH=/_N_DEF_DIRREDEF $MA_CTRLOUT_SEGMENT_NR APR 2 APW 2REDEF $MA_ENC_SEGMENT_NR APR 2 APW 2REDEF $SN_JOG_CONT_MODE_LEVELTRIGGRD APR 2 APW 2M30The file becomes active when the next _N_INITIAL_INI is read in.Various protection levels are specified for writing (changing) or reading (partprogram or PLC). In the section lists of this document, the protection levels permachine data are indicated in the form of i/j.Example:MD 10000 has protection level 2/7, i.e. protection level 2 (corresponding topassword) is required to write data and protection level 7 to read data.In order to get into the machine data area, keyswitch position 3 is required atleast.References: /PGA/, Programming Guide, Section 1.5/FB/, A2, "Various Interface Signals"/BA/, Operator's GuideUnitThe unit refers to the default setting for the machine dataSCALING_FACTOR_USER_DEF_MASK,SCALING_FACTOR_USER_DEF andSCALING_SYSTEM IS METRIC = 1.© Siemens AG, 2003.
