Note
"Filter/Search" when inserting variables
The start value for "Filter/Search" of variables differs.
For example, to insert the variable $R[0], set "Filter/Search":
• 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.
Changing operands
Depending on the type of operand, you can increment or decrement the address by 1 place
at a time using the "Operand +" and "Operand -" softkeys.
Note
Axis names as index
For axis names, the softkeys "Operand +" and "Operand -" do not act as index, e.g. for
$AA_IM[X1].
