ABB Master is a totally modularized system at all levels. The high level consists of a family of
system products. An example of an advanced control system applying system products is
illustrated in Figure 1-1.
The system product is divided into HW modules and SW modules. In this way, the system
shows:
• High reliability
• High maintainability
• High integrity.
Hardware modules are replaceable units of the types power supply units, battery charger, and so
on, and printed circuit boards to be located in subracks.
The assembled program modules defining the product’s overall functionality are examples of
software modules. The different PC elements represent the lowest level of software
modularization exposed to you.
Further modularization exists to simplify different situations, for example sales, design,
application building and so on. Composite units are made by basic modules. Primarily, you can
find such packages in the Product Guide and other tendering and sales documentation.
For example, you will encounter the concept of a basic unit. Basic unit is used when you are
ordering as a name for the smallest unit to be ordered or a platform for further enlargement with
alternatives and options.

Controller and process I/O are separate products. This means that, in this manual, you will find
only short presentations of supported I/O systems and I/O boards. For more in-depth
information, see separate I/O documentation.
The Advant Controller 450 includes:
• CPU with memory residing the fixed internal program (the system software) and the
application program
• Communication submodules
• System software backup submodule
• A backup power supply including a battery charger
• 5 V regulators.
• A supervision module
• Submodule carriers.
You use submodule carriers and submodules to equip a subrack, which provides great flexibility
in combining communication submodules of different kinds.
For a physical view of a medium hardware configuration, including an I/O subrack, see
Figure 1-7. The denominations of communication link types and system functions used are
made clear in the following subsections, beginning with Section 1.7.2, Product Structure.
