The SCADAPack x70 provides internal flash storage and support for external USB storage media. The internal flash storage is described below. For more information about support for plug-in storage media, see USB Ports. The SCADAPack 470 and SCADAPack 474 include a microSD card slot. See MicroSD Card Slot.
Operating system flash
The operating system flash stores the SCADAPack firmware. The firmware implements the communications protocols — DNP3, TCP/IP, Modbus and others — the services that support the SCADAPack object database and the SCADAPack x70 logic that runs the user-created sequence and control applications.
The SCADAPack firmware can be upgraded locally or remotely.
User file system flash
The user file system flash stores the SCADAPack configuration, user logic, data files and other custom user files. See the Specifications for details on storage space.
Bootloader flash
The bootloader firmware resides in a separate flash memory chip. The bootloader firmware is the first code executed by the CPU when power is applied to the SCADAPack. It configures the SCADAPack hardware then verifies, loads and executes the operating system firmware. It also provides firmware upgrade facilities.
The bootloader firmware can be upgraded locally or remotely.
