Programming if-then decisions
Possibilities for jump inputs
The following inputs are possible for the condition
IF
:
Numbers
Texts
Q, QL, QR
QS
(string parameter)
You have three possibilities for entering the jump address
GOTO
:
LBL NAME
LBL NUMBER
QS
Press the
JUMP
soft key to call the if-then conditions. The control
then displays the following soft keys:
Soft key Function
FN 9
: IF EQUAL, JUMP
e. g.
FN 9: IF +Q1 EQU +Q3 GOTO LBL
"UPCAN25"
If both values or parameters are equal, jump to
specified label
FN 9
: IF UNDEFINED, JUMP
e. g.,
FN 9: IF +Q1 IS UNDEFINED GOTO LBL
“UPCAN25“
If the specified parameter is undefined, then a
jump is made to the specified label
FN 9
: IF DEFINED, JUMP
e. g.,
FN 9: IF +Q1 IS DEFINED GOTO LBL
“UPCAN25“
If the specified parameter is defined, then a jump
is made to the specified label
FN 10
: IF UNEQUAL, JUMP
e. g.
FN 10: IF +10 NE –Q5 GOTO LBL 10
If both values or parameters are unequal, jump to
specified label
FN 11
: IF GREATER, JUMP
g. g.
FN 11: IF+Q1 GT+10 GOTO LBL QS5
If the first value or parameter is greater than the
second value or parameter, jump to specified
label
FN 12
: IF LESS, JUMP
e. g.
FN 12: IF+Q5 LT+0 GOTO LBL "ANYNAME"
If the first value or parameter is smaller than the
second value or parameter, jump to specified
label
