Sample Programming
 Example for Writing Data with Power OFF Retain Attribute That Is Updated at Unit
Restart for an NX Unit
The following programming sets the Ch1 Input Moving Average Time object parameter for an NX-
AD2203 AC Input Unit connected to an EtherCAT Coupler Unit to 500 μs.
The node address of the EtherCAT Coupler Unit is 10.
The specifications of the Ch1 Input Moving Average Time object parameter are as follows:
Item
Index
Subindex
Setting for 500 μs
The Ch1 Input Moving Average Time object parameter has a Power OFF Retain Attribute and it is
updated when the Unit is restarted. Therefore, the following procedure is used.
1
Use the NX_ChangeWriteMode instruction to change the Unit to a mode that allows writing
data.
2
Use the NX_WriteObj instruction to write data to the Unit.
3
Use the NX_SaveParam instruction to save the data that you wrote.
4
Use the RestartNXUnit instruction to restart the Unit.
