Introduction CP384
1.2 Product Overview
The CP384 Digital Input and Digital Output Controller is part of a comprehensive concept to
provide CompactPCI system integrators with a complete range of CompactPCI I/O products
which include the functions of analog input, analog output, digital input, and digital output im-
plemented as separate individual boards. This concept ensures a maximum degree of system
design flexibility thus allowing efficient and effective usage of available resources.
As an enhancement to this concept, the CP384 combination board has been designed to im-
plement digital input and digital output functions on one board. The CP384 is a 3U/4HP Com-
pactPCI board which provides 24 channels that are organized into two separate clusters, one
cluster consisting of 16 channels for digital input, and one cluster consisting of 8 channels of
relay switched (SPDT) digital output.
The basic functions of this board are on the one hand to provide interfacing to the application
(process), perform D/D signal conversions, and to make raw digitized data available for further
processing via the 16 input channels, and on the other hand to provide a large number of au-
tomatically controlled, flexible digital outputs within a ruggedized board. The digital output clus-
ter requires external input voltages (process side) for operation, both for the outputs as well as
the supply voltage for the relay coils.
The major components involved in these processes are the front end (process side) signal con-
ditioning (digital input and digital output), the relays for the digital outputs, and the Digital Input
and Output Process and Communications (DIO ProComm) Controller which is realized in a
field-programmable gate array (FPGA). The DIO ProComm Controller is designed to provide
effective and efficient control of the digital input and output processes as well as interfacing to
the CPCI system controller.
