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 into an NC/PLC variable, the string is only displayed
correctly if the variable is parameterized on the NC side as a field variable of type "A" (ASCII).
Example of a field variable
Variable Format
DBx.DBBy[<number>] A
Inserting variables
The start value for "Filtering/searching" 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]
