Use Of Predefined Variables As Transfer Parameters; Incomplete Parameter List And Omission Of Parameters - Siemens SINUMERIK 840D Programming Manual

1.3 Programming cycles
Example
DEF CHAR FORM="E"
DEF REAL MID=5, FFR, FAL
DEF INT VARI=1
N10 FFR=0.1 FAL=0
N20 CYCLE100 (FORM, MID, FFR, ->
-> VARI, FAL)
3. Use of predefined variables as transfer
parameters
For defining cycles with parameters you may use
variables such as R parameters.
Example
DEF CHAR FORM="E"
N10 R1=5 R2=0.1 R3=1 R4=0
N20 CYCLE100 (FORM, R1, ->
-> R2, R3, R4)
As R parameters are predefined as real, it is
important to ensure that the type of the target
parameter in the cycle is compatible with the type
real.
More detailed information about data types and type
conversion and compatibility is given in the
Programming Guide. If the types are incompatible,
alarm 12330 "Parameter type ... incorrect" is issued.
4. Incomplete parameter list and omission of
parameters
If a defining parameter is not required for a cycle call
or it is to be assigned the value zero, it can be
omitted from the parameter list. A comma, "..., ,... "
must be written in its place to ensure the correct
assignment of the following parameters or the
parameter list must be concluded prematurely with
")".
