4.6.8.1

If control structure / If-Else control structure

Conditional execution - If ... Else ... EndIf
The control structure allows the conditional execution of two different operation blocks
dependent on whether the condition "exp" is fulfilled or not. If this is fulfilled (true), then the
first operation block "block1" is executed, else the second execution "block2" is executed.
Each of the two operation blocks can, in turn, contain control structures; this means that any
nesting depth is possible.
Example
250
If exp
block1
Else
block2
EndIf
CHANDATA(1)
If Up.Velo_X != null
If Up.Velo_X > ($MA_MAX_AX_VELO[AX1]+ 100)
$MA_MAX_AX_VELO[AX1] = Up.Velo_X
Else
$MA_MAX_AX_VELO[AX1] = 1000
EndIf
