CTI Janus Programmable Automation Controller IOG
3.2.2
Internal SD Card Installation
The Janus controller uses a Secure Data (SD) card for storage of configuration data, executable program,
application program source files, and user data files.
A high capacity SDHC card is pre-installed on all units shipped
from the factory. Contact CTI support if the SD card is missing.
Because all configuration and operational files are
contained on the SD card, the complete controller profile can be transferred to another unit simply by swapping
SD cards.
The receptacle for the internal SD card is located on the controller circuit board as shown in the following pictures.
To remove and replace the internal SD card:
•
Remove power to the base.
•
Remove the controller from the base.
•
To remove the card, apply insertion pressure until you hear a click, then release pressure.
•
To install the card, insert the card in the receptacle face up, with the beveled edge facing the receptacle.
Continue insertion until you hear a click, then release.
NOTE
A replacement SD card must have a write speed rating of at least 10 MB/s (Class 10). CTI recommends you
purchase an SD card with an industrial rating.
