Set the number of files and the file numbers to transfer. When bit 0 of the [Control Word Address] turns ON, CSV data from the CF Card/USB storage is written to the device/PLC. When bit 1 turns ON, device/PLC data is saved to the CF Card/USB storage according to the [Condition].
A maximum of 64 files can be transferred simultaneously.
Control
Data transfers depending on the address bit 0 or bit 2 state.
Ensure that all bits in this address are set to "0" when the GP unit is turned on.
Do not turn multiple bits ON at the same time.
The Condition Name Search transfer can only be run when using the [Condition Name Search Feature].

Number of Files
Specify the number of CSV files to transfer (from 1 to 64).

After that, the desired transfer order is stored by file number.
Automatic Transfer (Condition Action) Timing Chart
When the control address bit 0 (or bit 1) turns ON, the Transferring bit (status bit 0) turns ON.
When a data transfer is completed successfully, the Transferring bit turns OFF, and the Transfer Complete Flag (status bit 1) turns ON.
When the data transfer is completed, determine the Transfer Complete Flag via the device/PLC and turn OFF the Control Address bit.
Turning OFF the Control Address bit automatically turns OFF bit 1 (transfer complete) in the status address.
If the transfer fails, the Transferring Bit turns OFF, and the error code is set in the error status (status bits 12-15). Before starting the next transfer, clear the Status and Control bits to 0 and turn on the required Control bit.
