Chapter 1 Overview
Introduction
Derived from the same fundamentals used in building the Galil motion controllers, the RIO-47xxx is a
programmable remote I/O controller that conveniently interfaces with other Galil boards through its Ethernet
port. The RIO is programmed exactly the same way as a DMC (Digital Motion Controller) with the
exception of a few revised commands and the removal of all motion-related commands. Communication
with the RIO even works the same way as with other Galil controllers, and it utilizes the same software
programs. Interrogation commands have been included to allow a user to instantly view the entire I/O status,
I/O hardware, or Ethernet handle availability (see the TZ, ID and TH commands).
The purpose of an RIO board is to offer remote I/O in a system and the ability to synchronize complex
events. To do this, the RIO consists of two boards – a high speed processor with integrated Ethernet and an
I/O board consisting of digital inputs, digital outputs, analog inputs, and analog outputs. If different I/O
requirements are required –a custom I/O board can be made to mate up directly with the RIO processor.
