PACSystems™ RX3i and RSTi-EP CPU Reference Manual Section 2 GFK-2222AK October 2019 2.1.7 Removable Data Storage Devices (RDSDs) The RX3i CPE302/CPE305/CPE310/CPE330 and RSTi-EP CPE100/CPE115 CPUs provide the ability to transfer applications to and from Removable Data Storage Devices (RDSD). Typically, these are USB-compatible devices, such as a memory stick, smart phone, digital camera or an MP3 device.
Page 29: Uploading A Project From The Cpu To The Rdsd
PACSystems™ RX3i and RSTi-EP CPU Reference Manual Section 2 GFK-2222AK October 2019 2.1.8 Uploading a Project from the CPU to the RDSD Flash devices write in whole memory blocks and memory block sizes vary among devices. The amount of space used by a project may vary between RDSDs due to the differences in minimum block sizes and therefore the number of blocks used by a project.
Page 30: Downloading A Project From The Rdsd To The Cpu
PACSystems™ RX3i and RSTi-EP CPU Reference Manual Section 2 GFK-2222AK October 2019 Notes: Only one application project can be stored to the RDSD at a time. Before the RX3i writes the project to the RDSD, any previous application is removed; if a directory named PACS_Folder exists on the RDSD at the start of the upload, it is deleted with all of its contents.
Page 31 PACSystems™ RX3i and RSTi-EP CPU Reference Manual Section 2 GFK-2222AK October 2019 CAUTION If the RDSD is removed during data transfer to the CPU, the RX3i controller will generate a fatal fault (sequence store fault) and SYS FLT LED will turn red. You will need to clear the fault tables through a programmer connection or by power cycling the CPU with the Energy Pack disconnected before attempting to download again.

The Logic window is executed in its entirety each sweep. The Communications windows can be set to execute in a Limited or Run-to-Completion mode.
Page 92 PACSystems™ RX3i and RSTi-EP CPU Reference Manual Section 4 GFK-2222AK October 2019 4.1.2.2 Constant Sweep Mode In Constant Sweep mode, each sweep begins at a specified Constant Sweep time after the previous sweep began. The Logic Window is executed in its entirety each sweep. If there is sufficient time at the end of the sweep, the CPU alternates among the Controller Communications, Backplane Communications, and Background Windows, allowing them to execute until it is time for the next sweep to begin.
