23 Macro
23-26
Example
• IF ($u100 < 10) (W)
$u100 = $u100 + 1 (W)
ELSE
$u100 = 0 (W)
ENDIF
“$u100 = $u100 + 1” is executed when $u100 is smaller than 10. When $u100 is 10 or more,
“$u100 = 0” is executed.
• Comparison of data in BIT format
IFNZ ($u100-00) (B)
$u100 = $u100 + 1 (W)
ELSE
$u100 = 0 (W)
ENDIF
If $u100-00 is ON, $u100 = $u100 + 1 is executed. If $u100-00 is OFF, $u100 = 0 is executed.
Restrictions
• IF-ELSE-ENDIF commands can be nested up to 8 levels.
Supplementary information
• An error occurs to the macro editor when any of the following conditions is met.
1) When IF-ELSE-ENDIF commands are nested beyond 8 levels;
2) When the number of IF commands is not the same as the one of ENDIF commands;
3) When the number of IF commands is not the same as the one of ELSE commands;
4) When FOR and NEXT commands are specified in a series of IF-ELSE-ENDIF commands.
Example: IF ($u100 > 0)
IF ($u100 < 10)
There are 9 or more IF commands between IF-ENDIF
commands.
:
IF ($u200 == 1)
ENDIF
Example: IF ($u100 == 0)
There are two IF commands while there is one ENDIF
command.
IF ($u100 == 0)
ENDIF
Example: IF ($u100 == 0)
There is one IF command while there are two ELSE
commands.
