2.1 Hardware
The identification and P&P connection of modules are based on
the developed Intelligent Modular Periphery Interface (IMPI) and
special architecture of modules (see Figure 2). The IMPI has three
sets of lines: a) input and output power supply lines b) IMP bus
enabling detection of modules’ connection order, identification
and energy management, and c) data lines enabling direct
communication with peripherals. Each module is equipped with
single Module Control and Identification Unit (MCIU,
MSP430G2453 are used as those in our demo) which stores the
data about on-node peripherals and enables MPU (STM32F207
ARM-based controller in demo) to control modules. Note, that
unlike the existing solutions, modules in IMPI are addressed
based on their order of connection. The further details about the
architecture, underlying mechanisms and technical solutions, and
parameters of our platform are reported in [4-5].
