Address when Using the Condition Name Search Feature
After storing the Condition Name to search, turn the [Control
Word Address] transfer bit (bit 2) from OFF to ON to : search for
CSV files within the CF Card/USB storage and transfer all CSV files
that match the search condition name.
When bit 2 turns ON, search for the file with
the condition name that matches the text string designated in
[Search Word Address], and write the matching CSV data to the
PLC.

Ensure that all bits in this address are set to
"0" when the GP unit is turned on.

(Condition Name Search transfer) turn ON at the same time, neither
operation is performed. Turn ON only bit 2.

Condition Name Search Transfer Timing
Chart
When the control address' bit 2 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. When the trigger is OFF, the [Transfer Completion] bit turns
OFF.
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.
