1.9 Predefined functions
The
script
language
offers various string processing and standard mathematical functions. The
function names listed below are reserved and cannot be overloaded.
Function name Description
Ncfunc cap read The function copies a value from the specified address into a local
variable. If the read operation was error-free, then the return variable
contains the value zero.
Contrary to the operation instruction, in the event of a fault, this func‐
tion does not interrupt the processing of the script operations.
Syntax:
<function name="ncfunc.cap.read" return="error">
lokale variable, "address"</function>
Example:
<let name="error"></let>
<function name="ncfunc.cap.read" return="error">
3, "drive/cu/p0009"</function>
<if>
<condition>error != 0</condition>
<then>
<break />
</then>
</if>
Ncfunc cap write The function writes a value into the specified variable. If the write op‐
eration was error-free,
then the return variable contains the value zero.
Contrary to the operation instruction, in the event of a fault, this func‐
tion does not interrupt the processing of the script operations.
Syntax:
<function name="ncfunc.cap.read" return="error">
local variable or constant, "address"</function>
Example:
<let name="error"></let>
<function name="ncfunc.cap.write" return="error">
