Writing Variable Data
Using Dnc1Test
1 Click the <Write Variable> button in the main screen.
2 From the [Station Address] combo box, select the station address of the
NC.
3 If the specified NC unit is the multi-path system, enter the tool post
number. If not so, you don’t need to enter it.
4 To write the variable data, enter the parameters in [Function Code], [Big
Class], [Middle Class], [Small] Class], [Data Type], [Data Length], and
[Data Amount].
If you want to express the parameter value in hexadecimal, the parameter
value must be preceded “&H”. For example, the hexadecimal value of 33
must be specified by “&H33”.
5 For more information about the function code, the big class, the middle
class, the small class, the data type, the data length, and the data amount,
refer to “Appendix 1 DNC1 DATA Function Details” of the
Programming manual.
6 If you want to write more than one variable data, separate each value by
a space character.
For example, if you want to write the PMC data values of “7”, “17” and
“23”, the character string “7 17 23” must be specified in the [Data] text
box.
7 Click the <Run> button.
8 If the value of 0 is displayed in [RESULT], the writing of the variable
data is successful. Otherwise, it is failed.
