Yaskawa Remote I/O Controller LAN Node PCB for use with Microtrac DSD LAN - Manual

INTRODUCTION
The Remote Input/Output Controller
LAN Node PCB (RIO) provides the MicroTrac
DSD system with the ability to have remote
inputs and outputs with a minimal amount
of wiring. The RIO has some I/O of its own
and can support up to 6 Remote I/O boards
through use of an I/O expansion bus. The
RIO communicates through use of a Local
Area Network (LAN) using a proprietary
message protocol defined by MagneTek.
This protocol allows messages to be sent to
and from the RIO in order to pass input and
output information (e.g., turn on an output,
give the value of an A/D input, etc.).
This document explains the
hardware and software operations of the
Remote Input/Output Controller LAN Node
PCB (RIO).
HARDWARE DESCRIPTION
POWER REQUIREMENTS
The power connector on the RIO is
used to supply the RIO and the Remote I/O
boards with power. The RIO supplies power
to each of the Remote I/O board through
the I/O expansion bus. The power require-
ments for each of the voltages connected to
the RIO, therefore, include the power drawn
by the RIO and the power drawn by each of
the Remote I/O boards.
In order to select a properly sized
power supply, the current (I) requirements
of the PCBs for each of the voltages must be
known. The I requirements are as follows:
I for +5 VDC = (I of RIO) + (I of I/O boards)
+ (I of external loads)
= (1250 mA)+(I of I/O boards)
+ (I of external loads)
I for +15 VDC = (I of RIO)+(I of I/O boards)
+ (I of external loads)
= (2.8 mA) + (I of I/O boards)
+ (I of external loads)
I for -15 VDC = (I of RIO)+(I of I/O boards)
+ (I of external loads)
= (273 mA)+(I of I/O boards)
+ (I of external loads)
I for +24 VDC = (I of RIO)+(I of I/O boards)
+ (I of external loads)
= (0 mA) + (I of I/O boards)
+ (I of external loads)
