The maximum number of data that can be set in one file (ZR*****.csv) is 10,000 (or 5,000 when the data is 32 bit).
If the number of data is large, transfer may take some time. The time from when transfer starts to when transfer is complete can vary from several seconds to several minutes.
While a transfer is occurring, the display of Parts may not update properly or may become slow. Screen changes and other operations may also become slow.
If a screen change occurs during transfer, in order to read the screen information, the transfer may take some time.
Wait until a transfer completes before initiating another one. If a transfer is started before the previous one ends, such as when an automatic transfer and manual transfer occur at the same time, the second transfer operation may not be accepted.
If a project transfer or changing to offline mode is perfomed while transferring data, the data may not be transferred completely.
Only the selected CF Card or USB storage device will operate.
If multiple files are stored in the CF Card/USB Storage [file] folder, transferring to the device from CF Card/USB Storage may take up to several minutes.
Do not call up the screen for transfer CSV data or screens that use the CF Card/USB storage when the CF Card/USB storage is not installed on the display unit. It may not work properly.
When a CF Card/USB storage error occurs, temporary files may remain on the CF Card/USB storage device.
When overwriting, the required available space on the CF Card or USB Storage is at least double the size of the actual data. If there is more data than available space, a write error occurs during transfer.
To free up space, you can move out data that is not needed immediately between the CF Card and USB Storage.
A.5 Transferring Data Between a CF Card and a USB Storage Device
When transferring data from device/PLC to CF Card/USB Storage, the [file] folder is created if it does not already exist. If the CF Card/USB storage is not reset or the folder cannot be created, a CF Card/USB storage error occurs.
When you save the existing CSV data in the CF Card/USB Storage, if there is data entered in the third row or later in the CSV data, it will be deleted upon saving.
The number of times that data can be written on a CF Card is limited. (Approximately 100,000 times for rewriting 500 KB.)
To format the CF Card/USB storage on your PC, select FAT16 or FAT32. When format to NTFS, the display unit cannot recognize the CF card or USB storage.
Do not connect more than one USB storage device. If you do so, the USB devices may not be recognized properly.
When using Float, up to 17 digits or 16 decimal places can be read, but an error may occur after the seventh digit due to floating point limitations.
When transferring from the CF card or USB storage to the device/PLC, tabs and single-byte space characters are skipped when read. Furthermore, when there are periods or commas in comments, there are instances when the data text cannot be read properly. When there are two or more commas in a single row, data after the second comma is not read.
When ejecting a CF Card, make sure that the CF Card access LED lamp turns OFF. Data in the CF Card may be damaged.
When accessing a CF Card, be sure not to power OFF or reset the display unit, or eject the CF Card. Create an application screen on which the CF Card cannot be accessed, and on that application screen, you may power OFF or reset the GP, open and close the CF Card cover, and eject the CF Card.
When inserting a CF Card, check the front and back sides and the connector position of the card. If the CF Card is inserted the wrong way, the data, the CF Card, or the display unit may be damaged.
Use a CF Card manufactured by Digital Electronics Corporation. If a CF Card manufactured by another company is used, the contents of the CF Card may be damaged.
Please make sure to back up all CF Card data.
Please refrain from doing the following, as it can result in damage to data and equipment:
Bending the CF Card
Dropping the CF Card
Spilling water on the card
Touching the CF Card's connectors directly
Disassembling or modifying the CF Card
While accessing the USB device, do not reset the display unit or remove the USB storage device. Data in the USB Storage device may be damaged.
To remove the USB storage device safely, design the system to remove the device only after turning ON system variable #H_Control_USBDetachTrigger and after confirming #H_Status_USBUsing is OFF.A.7.2.1 Bit - #H System Variables
Please make sure to back up all data on USB storage devices.
When formatting the USB storage device using FAT16 or FAT32 on a PC, the maximum usable capacity is 2 GB.
The display unit cannot use USB storage devices that are FAT16 or FAT32 with greater than 2 GB.
Restrictions for Manual Transfer
First set the Condition on [Recipe] - [Transfer CSV Data (Condition)], then place the Special Data Display [Data Transmission] on the screen.
Only one Special Data Display [Data Transmission] can be placed per screen.
Up to 32 Special Data Display [Data Transmission] can be placed per project.
When selecting transfer files by touch, multiple files can only be selected from the area displayed in a Special Data Display [Data Transmission]. (The maximum number of display rows is 50.) If the displayed page is changed with the [Data Transmission] scroll switch, the selection will be cancelled.
If an error occurs while transferring multiple files, transfer stops at that file. Subsequent files are not transferred.
When transferring data from the device/PLC to the CF Card/USB Storage, the data is saved in the file set in the Special Data Display [Data Transmission]. The Condition Name (Group Name) is overwritten by the Condition Name set in the Common Settings - Condition area.
If the number of data designated in the condition settings differs from that in the file, the smaller number of data are transferred.
Ensure that the file numbers set in the condition settings ([Start] to [End]) are not repeated in multiple conditions. If file numbers are repeated in several conditions, data are transferred according to the condition with the smaller number.
Restrictions on Automatic Transfer (Conditional Action)
A maximum of 64 files can be transferred at one time.
If an error occurs while transferring multiple files, transfer stops at that file. Subsequent files are not transferred. Transfer occurs in order starting from the top file number storage address.
If the number of data designated in the condition settings differs from that in the file, the smaller number of data are transferred.
Ensure that the file numbers set in the condition settings ([Start] to [End]) are not repeated in multiple conditions. If file numbers are repeated in several conditions, data are transferred according to the condition with the smaller number.
If the number of files is not set, data are transferred even when the [Control Word Address] turns ON. Also, status will not restart.
When data is transferred from a device/PLC to a CF Card/USB Storage device and the target folder does not exist, the [file] folder is created for saving the data. If the CF Card/USB storage is not reset or the folder cannot be created, a CF Card/USB storage error occurs.
Restrictions on Automatic Transfer (Address Action)
One CSV Data can be transferred at a time.
When transferring CSV Data from CF Card/USB Storage to Device/PLC using a memory link connection, set the [Address Mode] to "0".
If the number of data exceeds the set range (10,000 when the data length is 16 bit, 5,000 when it's 32 bit), any excess values are not transferred.
Ensure that the device code/address code is set correctly. If the device address is out of range or refers to a non-existent device, a communication error occurs and no transfer is performed.
When data is transferred from a device/PLC to a CF Card/USB Storage device and the target folder does not exist, the [file] folder is created for saving the data. If the CF Card/USB storage is not reset or the folder cannot be created, a CF Card/USB storage error occurs.
