CHAPTER 6: COMPACTFLASH

6.1 General

Chapter Six provides an overview of the CompactFlash feature in QX OCS models and Cscape Software.

Note: For detailed information regarding Removable Media (RM) function blocks and parameters,

refer to the help file in Cscape Software.

6.2 Compact Flash Overview

All QX OCS models provide a slot for a CompactFlash memory card. The Removable Media manager is

a graphical object that allows viewing the filenames, size and dates of files and directories on a

CompactFlash card. The operator can optionally change directories, delete files and format a new flash

card. This object also supplies status information such as color change on card OK, card full and card

missing status. The file view includes total card capacity and remaining free space.

6.2.1 Accessing Files with an QX OCS

a. Insert a CompactFlash card into the QX OCS CompactFlash slot.

b. If not formatted, use the Removable Media Manager object to format the card.

c. The QX OCS ladder application program can read and write to the CompactFlash card. The file

is saved as a .csv file, which is compatible with several PC applications such as Excel.

6.2.2 Accessing Files with a PC

a. Insert or connect the CompactFlash memory card to the PC according to the manufacturer’s

instructions.

b. The PC typically sees the CompactFlash card as a removable storage device like a small solid-

state hard drive. Files can be read from and written to the CompactFlash card in the same way

they are read/written to a standard hard disk. The only file format that can be read or written by

an OCS application is a .csv (comma separated value) file.

6.3 Removable Media (RM) Function Blocks in Cscape

Note: For detailed information regarding RM function blocks and parameters, refer to the help file

in Cscape Software.

into the controller register space. The file format of the value file uses commas to separate

values.

b. Write RM csv

This function allows writing of a comma-separated value file to the CompactFlash interface from

the controller register space. The file format of the value file uses commas to separate values.
