Examples
Example 1: No keyword
Program code Comments
DO $A_OUTA[1]=$AA_IN[X] ; Actual value output to analog output.
Example 2: WHENEVER
Program code Comments
WHENEVER $AA_IM[X] > 10.5*SIN(45) DO …
Comparison with an expression
calculated during preprocessing
WHENEVER $AA_IM[X] > $AA_IM[X1] DO …
Comparison with other main run
variable.
WHENEVER ($A_IN[1]==1) OR ($A_IN[3]==0) DO ...
Two comparison operations that
are gated with one another.
Example 3: EVERY
Program code Comments
ID=1 EVERY $AA_IM[B]>75 DO POS[U]=IC(10) FA[U]=900 ;
lways when the actual value of axis B
exceeds the value 75 in machine
coordinates, the U axis should move
forwards by 10 with an axial feed.
Further information
Conditions
The condition is a logical expression which can be built up in any way using Boolean
operators. Boolean expressions should always be given in brackets.
The condition is checked in the interpolation cycle.
A G code can be given before the condition. This allows defined settings to exist for the
evaluation of the condition and the action/technology cycle to be executed, independent of
the current part program status. It is necessary to separate the synchronized actions from
the program environment, because synchronized actions are required to execute their
actions at any time from a defined initial state as a result of fulfilled trigger conditions.
Applications
Definition of the systems of measurement for condition evaluation and action through G
codes
G70, G71, G700, G710.
A G code specified for the condition is valid for the evaluation of the condition and for the
action if no separate G code is specified for the action.
Only one G code of the G code group may be programmed for each part of the condition.
