Ncfunc cap write
Easy XML
Programming Manual, 12/2017, 6FC5397-1DP40-6BA1
Description
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.
Attributes:
● return - Execution status
– Value = 0 - faultless
– Value = 1 - The variables could not be read
● rows - Number of additional lines of an array to be written (optional)
If an array index is defined for the reference variables, as from this
index, the function copies the values into the target variable.
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">
0, "drive/cu/p0009"</function>
<if>
<condition>error != 0</condition>
<then>
<break />
</then>
</if>
