Overview
The LonWorks Core Module
(53011) provides a simple, cost-effective method of adding
LonWorks technology to any control system. The module consists
of a miniature circuit card containing a Neuron 3150 Chip,
reprogrammable 32Kbyte flash memory, 32Kbyte RAM, 10MHz crystal
oscillator, and connectors for power, application I/O or host
interface, and a transceiver.
This LonWorks Core Module
includes standard Neuron Chip firmware with extensions for
automatic configuration of transceiver parameters, output of a
packet transmitted signal, manual device recovery, and a
Microprocessor Interface Program (MIP) that can be used to
convert the module to a LonWorks network interface.
The firmware comes
preconfigured with many common LonWorks transceiver parameters.
Five transceiver identification (ID) pins on this module select
the appropriate transceiver type.
The packet send output uses an
additional output pin provided by the hardware to provide an
indication of network activity. This output is asserted low for
approximately 40ms when a packet is sent from the network
processor to the MAC processor on the Neuron Chip.
Logic on this module provide 2
additional bit outputs. One of these outputs is used as a packet
send indicator by the firmware; the other can be used either as
a general purpose bit output or as an uplink data interrupt
request when using the MIP.
The manual device recovery
feature provides a means to recover a device that has been
loaded with a defective application that renders it inoperable.
The annual device recovery features allows such a device to be
recovered by activating the service input prior to activate the
service input after releasing the reset input. After
approximately 10 seconds, the device will become
applicationless, allowing a network services tool to reload a
new application.
The reprogrammable flash memory
makes the WLM-10 core module ideal for controlling devices that
may be upgraded or modified after installation, e.g., complex
sensors, motor controllers, or user interface devices.
The integral MIP firmware
allows the module to be used as an applications processor or as
a network interface for another host processor. Any host with
memory-mapped I/P or an 8-bit parallel data bus with 3 control
lines and an optional uplink interrupt may be used. The MIP
allows the host to receive asynchronous updates from up to 4096
network variable connections, each consisting of an unlimited
number of network variables; as with any node, there are no
limitations on the number of network variables that can be
written or polled. The optional uplink interrupt eliminates the
need for polling by the host for incoming data and thereby
reduces delays.
Specifications for the network
driver are included in the Echelon's Microprocessor Interface
Program (MIP) User's Guide. A sample host application and source
code for a network driver for DOS (or the basis for a network
driver for any host) is available on Echelon's LonLink BBS.
Using this core module can save
hundreds of hours of development time compared with designing
custom modules, and minimizing time-consuming and expensive
laboratory testing, component selection, and layout redesign
work.
This core module is
exchangeable with Echelon's LTM-10A module.
