Echelon I/O Model Reference for Smart Transceivers and Neuron Chips - Manual (Page 3)

I/O Model Reference iii
Welcome
For the various input/ouput (I/O) pins on an Echelon ® Smart Transceiver, an
Echelon Neuron ® 5000 Processor, or Series 3100 Neuron Chip, Echelon’s Neuron
C programming language provides a set of I/O models that allow a program to
define I/O objects . An I/O model is an abstract definition (including the relevant
firmware driver) of hardware I/O for a Neuron Chip or Smart Transceiver; an I/O
object is software instance of the specific I/O model. Together, they provide
programmable access to one or more I/O pins in a specified configuration and for
a specified input or output waveform definition.
This document describes the many different I/O models that are available for use
with the Neuron Chips and Smart Transceivers. With only a few exceptions, an
I/O model can be used with any Series 3100 device or any Series 5000 device.
Where applicable, this document identifies differences in the I/O models that are
specific to a particular device type.
The information in this document supersedes the equivalent information for
Series 3100 devices contained in the FT 3120 / FT 3150 Smart Transceiver Data
Book , PL 3120 / PL 3150 / PL 3170 Power Line Smart Transceiver Data Book ,
Neuron C Programmer’s Guide , and Neuron C Reference Guide .
Audience
This document assumes that you have a good understanding of general Neuron C
language programming concepts and techniques. It also assumes that you are
familiar with the device requirements for Neuron Chips and Smart Transceivers.
