10.5.2 Call-by-value parameters
Function
Technology cycles can be defined using call-by-value parameters. Simple data types such
as INT, REAL, CHAR, STRING, AXIS and BOOL can be used as parameters.
Note
Formal parameters that are transferred as call-by-value cannot be arrays.
Actual parameters can also comprise default parameters (see "
Default parameter
initialization (Page
623)").
Syntax
ID=1 WHEN $AA_IW[X]>50 DO TEC(IVAL,RVAL,,SVAL,AVAL)
A default value is transferred for non-initialized actual parameters:
ID=1 WHEN $AA_IW[X]>50 DO TEC(IVAL,RVAL,,SYG_SS[0],AVAL)
10.5.3 Default parameter initialization
Function
Default parameters can also be provided with an initial value in the PROC instructions.
Syntax
Assign default parameters in the technology cycle:
PROC TEC (INT IVAL=1, REAL RVAL=1.0, CHAR CVAL='A', STRING[10] SVAL="ABC", AXIS
AVAL=X, BOOL BVAL=TRUE)
If a current parameter consists of a default parameter, the initial value is transferred from the
PROC instruction. This applies both in the part program and in synchronized actions.
Example
Program code Comments
TEC (IVAL, RVAL, SVAL, AVAL) ; For CVAL and BVAL, the initial value applies
