Section 6-3
Operand
Nil
Description
• If the conditional expression is satisfied, processing 1 will be executed. If
the conditional expression is not satisfied, processing 2 will be executed.
• Processing 1 is described between IF and ELSE (can be described over
multiple lines).
• Processing 2 is described between ELSE and ENDIF (can be described
over multiple lines).
• ELSE and processing 2 can be omitted.
Repeat While
(WHILE...WEND)
While the conditional expression is being satisfied, processing between
WHILE and WEND is repeatedly executed.
Command type
WHILE: Multiple execution command
WEND: Multiple execution command
Format
WHILE_<conditional expression>;
<processing>
WEND;
Ex: WHILE_#DW0001 = = 1;
INC MOVE [J01]100.00 [J02]200.00;
WEND;
The formats of conditional expressions are shown in the following table.
Immediate values and variables are the only comparison objects. If a different
data type is used, an alarm will occur in pre-analysis.
