Removable Data Storage Device (RDSD)
The CPE330 user program and/or memory contents may be saved to a USB device
via the RDSD UPLD pushbutton or loaded into the CPU from a USB device via the
RDSD DNLD pushbutton. Similarly, data can be selected and saved. In this way, an
application may be cloned and copied from one device to another.

Periodic Maintenance
4.1.
Real-Time Clock Battery
The CPE330 is shipped with a real time clock (RTC) battery
installed (see Figure 3). Over time, this battery will need to be
replaced. No action is required during initial installation.
Should the RTC battery fail, the CPU date and time will be
reset to 12:00 AM, 01-01-2011 at start-up. The CPU operates
normally with a failed or missing RTC battery; however, the
initial CPU time-of-day (TOD) clock information will be
incorrect.
There are no diagnostics or indicators to monitor RTC battery
status. The RTC battery has an estimated life of 5 years and
must be replaced every 5 years on a periodic maintenance
schedule.
