Meaning:
<result>: Data type of the specified system/user variables
Data type: INT
Range of val‐
ues:
1 = BOOL
2 = CHAR
3 = INT
4 = REAL
5 = STRING
6 = AXIS
7 = FRAME
In case of fault
< 0 The specified variable name has not been assigned to a sys‐
tem parameter or a user variable.
GETVARTYP: Reading of the data type of a system/user variable
<name>: Name of the system/user variables
Data type: STRING
Example:
Program code Comment
DEF INT result=0
DEF STRING name="R"
result=GETVARTYP(name) ; Determine the type of the R parameter.
IF (result < 0) GOTOF error
The value 4 is returned as result. This corresponds to the REAL data type.
3.1.1.17 Possible type conversions
The constant numeric value, the variable, or the expression assigned to a variable must be
compatible with the variable type. If this is the case, the type is automatically converted when
the value is assigned.
Possible type conversions
