Compact Flash Overview
All QX751 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 QX751 OCS
a.
Insert a CompactFlash card into the QX751 OCS CompactFlash slot.
b. If not formatted, use the Removable Media Manager object to format the card.
c. The QX751 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.
