Inserting variables
The start value for "Filter/Search" of variables differs. For example, to insert the variable $R[0],
enter the following start value:
● The start value is 0 if you filter according to "System variables".
● The start value is 1 if you filter according to "All (no filter)". In this case, all signals are
displayed and shown in the OPI notation.
The GUD from the machine data is only displayed in the Search window for the variable
selection when the associated definition file has been activated. Otherwise, the sought
variables must be entered manually, e.g. GUD/SYG_RM[1]
The following machine data is representative for all variable types (INT, BOOL, AXIS, CHAR,
STRING): MD18660 $MN_MM_NUM_SYNACT_GUD_REAL
Searching for drive variables
The restriction of the search is performed in this case via the selected drive object. In the
Search window, you can restrict the selection by entering alphanumeric values, for example.
Further restrictions of the selection are possible via the "All" or "Recommended"
interconnections.
