Notation examples
Permissible notation for variables:
● PLC variables: EB2, A1.2, DB2.DBW2, VB32000002
● NC variables:
– NC system variables: Notation $AA_IM[1]
– User variables / GUD: Notation GUD/MyVariable[1,3]
– OPI notation: /CHANNEL/PARAMETER/R[u1,2]
Note
If the PLC user program writes a string in an NC/PLC variable, the string will only be displayed
correctly if the variable is parameterized as a field variable of the type "A" (ASCII) on the NC
side.
Example of a field variable
Variable Format
DBx.DBBy[<number>] A
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. Alternatively, enter the
variable you are searching for manually, e.g. GUD/SYG_RM[1]
