CHAPTER 8: REMOVABLE MEDIA
8.1
Micro SD Overview
All RX-371 OCS models provide a slot for a Micro SD memory card. The Removable Media manager is a
graphic object that allows viewing the filenames, size and dates of files and directories on a Micro SD
card. The operator can optionally change directories, delete files and format a new SD 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.
8.1.1
Accessing Files with an RX-371 OCS
a.
Insert a Micro SD card into the RX-371 OCS Micro SD slot.
b. If not formatted, use the Removable Media Manager object to format the card.
c. The RX-371 OCS ladder application program can read and write to the Micro SD card. The file
is saved as a .csv file, which is compatible with several PC applications such as Excel.
8.1.2 Accessing Files with a PC
a. Insert or connect the Micro SD memory card to the PC according to the manufacturer’s
instructions.
b. The PC typically sees the Micro SD card as a removable storage device like a small solid-state
hard drive. Files can be read from and written to the Micro SD 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.
