2 HARDWARE ARCHITECTURE
The main components comprising devices based on the Px4x platform are as follows:
● The housing, consisting of a front panel and connections at the r
ear
● The Main processor module consisting of the main CPU (Central Processing Unit), memory and an interface
to the front panel HMI (Human Machine Interface)
● A selection of plug-in boards and modules with presentation at the rear for the power supply,
communication functions, digital I/O, analogue inputs, and time synchronisation connectivity
All boards and modules are connected by a parallel data and address bus, which allows the processor module to
send and receive information to and from the other modules as required. There is also a separate serial data bus
for conveying sampled data from the input module to the CPU. These parallel and serial databuses are shown as a
single interconnection module in the following figure, which shows typical modules and the flow of data between
them.
