 Example for Writing Data with Power OFF Retain Attribute That Is Updated after
Writing the Data
The following programming sets the Ch1 Offset Value (One-point Correction) object parameter for an
NX-TS2101 Temperature Input Unit connected to an EtherCAT Coupler Unit to 0.3°C.
The node address of the EtherCAT Coupler Unit is 10.
The specifications of the Ch1 Offset Value (One-point Correction) object parameter are as follows:

Subindex
Value to write
The Ch1 Offset Value (One-point Correction) object parameter has a Power OFF Retain Attribute and it
is updated after the data is written. Therefore, the following procedure is used.
1
Use the NX_WriteObj instruction to write data to the Unit.
2
Use the NX_SaveParam instruction to save the data that you wrote.
