APPLICATIONS
GENERAL DESCRIPTION
The Microlon
network interface combines the
power of L
ON
W
ORKS
TM
technology with Grayhill
standard industrial I/O racks and modules.
Microlon
controllers may be distributed over
great distances yet provide seamless
interoperability. The robust communication
protocol LonTalk
is built into the firmware of the
Neuron
chip, the heart of L
ON
W
ORKS
technology.
The LonTalk
protocol follows the (7 layer) OSI
Reference Model for network protocols. This
technology is becoming the de facto standard for
interoperability. This frees the user from worrying
about network communication protocols.
In applications where the inputs and outputs that
need to be monitored and controlled are spread
out over a large area, running long signal lines
from the sensors and actuators to a central
controller can lead to numerous costly problems.
First, there is the time and expense of routing the
signal lines and shielding them from cross-talk,
EMI, and RFI. If this is not done properly, the cost
and time required to troubleshoot the wiring can

be exorbitant. Finally, making a change to the
system after installation is costly.
To alleviate this problem, install Microlon
units
and I/O modules near the sensors or actuators
and network the Microlon
units back to the host
computer (if a host is necessary). Peer-to-peer
communications, inherent with L
ON
W
ORKS
TM
technology, make it easy to extend signals
digitally, without signal loss.
Up to 63 Microlon
controllers (nodes) can be
networked together on a physical segment.
Units can be added with the aid of repeaters or
routers. Each node may contain up to 8 isolated
modules, configured as input or output, digital or
analog.
Microlon
controllers use one of two different
physical media types to communicate over the
network. Twisted pair, transformer isolated (TP/
XF) networks operate at 78 Kbps at distances up
to 6500 feet (2000 meters). In addition, FTT-10
operating at 78 Kbps at distances up to 1500 feet
(500 meters) is supported. Routers and Bridges
may be used to change the communication
media type from node to node. For example, a
Router may connect a group of nodes operating
over the FTT-10 medium to another group utilizing
the TPT-XF/78 medium.
Networks are installed and/or modified using the
Echelon LonBuilder Development system,
LonMaker installation tool or a third party tool.
LonMaker is a software package that runs on a
PC and communicates to Microlon controllers
using a Serial LonTalk Adapter (SLTA) or a PC
LonTalk Adapter (PCLTA). SLTAs are available
for all types of network media and converts them
to RS-232 at speeds up to 115,200 baud. PCLTAs
are ISA-bus cards that offer higher performance.
If the network contains other L
ON
W
ORKS
based
products, the NetProfiler
(included with
LonMaker
1
) is used to define the "parts catalogs"
tailored to the network. Otherwise, for networks
containing only Microlon
controllers, the "parts
catalog" will be provided, eliminating the need for
the NetProfiler package. Third party network
management, control and monitoring tools and
LonTalk Adapters are available, please contact
Grayhill for more information.
The Microlon
controller is shipped with a
standard application program which contains
everything necessary to interface with all of
Grayhill's I/O modules. Installation, Configuration,
and Troubleshooting are outlined in the 72-LON-
I8 manual (order separately). In addition, the
Microlon
application disk is supplied with the
manual and contains example source code and
the interface files ("parts catalog"). The
readme
file contains information not found in this manual.
If you have a LonBuilder or NodeBuilder
Development Tool, you may wish to modify the
application program and tailor it to your application.
