4.1.1. Images
The following table discusses IO-Link Master images.
4.1.2. Application Subassemblies
Application subassemblies are the components of the Application Base image. Application subassemblies
have 3-tuple or 4-tuple version numbers (for example, 1.10.1). The first two values in a subassembly version
correspond to the version of the application base assembly for which it was built and tested.
For example, a subassembly with version 1.10.3 was tested with application base version 1.10. When using
the SOFTWARE page or PortVision DX, an application subassembly can install only if its version number
matches that of the installed application base assembly. A subassembly with a version of 1.20.2.4 only installs
if the application base version is 1.20. It will not install on a device with application base version 1.09 or 1.20.
IO-Link Master Images
U-Boot Bootloader
U-Boot is a high-level bootloader that has networking and console command line
capabilities. Among other things, it implements a TFTP server and Comtrol
Corporation's new discovery protocol.
This verifies that a Linux kernel image exists in NAND, then copies it to RAM and
starts the IO-Link Master. The U-Boot version is displayed after the image name.
FPGA
The FPGA partition/image contains configuration data used by programmable
hardware within the IO-Link Master unit.
uImage - Primary/
Backup
The uImage contains the Linux kernel and the RAM-resident root file system. It does
not contain industrial protocol support or application-specific features.
There is a Primary and Backup version loaded on the IO-Link Master. The IO-Link
Master automatically reloads the Backup uImage if the file system corrupted.
The uImage version is displayed after the Primary/Backup uImage.
Application Base
The Application Base image comprises a flash-resident file system containing
application and protocol support.
The Application Base is built from a collection of application subassemblies -- each of
which may be updated individually between releases of the application base as a
whole.
The application subassemblies in the Application Base image are displayed in the
lower portion of the SOFTWARE web page.
The Application Base assembly has a 2-tuple version number: (for example, 1.10).
