26.10.3 About the Condition Name Search
Feature
When automatically transferring from CF Card/USB storage to
device/PLC, by designating the condition name of the file you want
to transfer, you can search for a matching CSV file within the CF
Card/USB storage [file]
folder and transfer that data to the device/PLC.
In the following picture, the CSV files that match the product
number (condition name) read from the barcode reader are
transferred to the device/PLC.
The designated [Search Word Address] uses 16 words, and the
condition name to be searched can be up to 32 characters (16
double-byte characters). After storing the search condition name,
turn ON bit 2 of the [Control Word Address]. The search and
transfer to the device/PLC begins. If there are multiple matching
files, the CSV data are transferred in order of file number.

Condition Name Search Storage Methods
If an index file (ZRINDEX.CSV) exists in the [file] folder, the
search scans the contents of the index file.
If there is no index file and the [file] folder contains a large
number of files, referencing and searching the condition names of
all CSV files may take a long time. (For example, if approximately
1,000 CSV files are searched, the search operation takes
approximately one minute.)
