272 Appendix C: Glossary
Mandatory Network Variable/Configuration Property
A network variable/configuration property that must be implemented by the functional block, as
specified by the functional profile that the functional block is instantiating.
Mini Kit
A tool for evaluating the development of control network applications with the ISO/IEC 14908
standard. You can use the Mini kit to develop a prototype or production control system that requires
networking, particularly in the rapidly growing, price-sensitive mass markets of smart light switches,
thermostats, and other simple devices and sensors. You can also use the Mini kit to evaluate the
development of applications for such control networks using the L
ON W ORKS platform.
Monitored Connection
A connector shape or reference connection on which network variable values are displayed and
updated.
Network Interface
A L ON W ORKS device that provides a layer 6 LonTalk interface to an external host computer such as a
computer or a handheld maintenance tool. Network interfaces include IP-852 interfaces (i.LON
SmartServer with IP-852 routing, i.LON 100 e3 Internet Server with IP-852 routing, and the i.LON
600 L
ON W ORKS -IP Server); U10/U20 USB network interfaces; and PCC-10 and PCLTA-10, 20, and
21 PCI network interfaces
Network Variable (NV)
Network variables allow a device to send and receive data over the network to and from other devices.
Network variables are data items (such as temperature, the state of a switch, or actuator position
setting) that a particular device application program expects to receive from other devices on the
network (an input network variable) or expects to make available to other devices on the network (an
output network variable).
Network Variable/Configuration Property Types
A network variable or configuration property type defines the structure and contents of the object. A
network variable type can be either a standard network variable type (SNVT) or a user-defined
network variable type (UNVT). A configuration property type can be a standard configuration
property type (SCPT) or a user-defined configuration property type (UCPT)
Neuron 5000 Processor
Echelon’s next-generation Neuron chip designed for the L ON W ORKS 2.0 platform. The Neuron 5000
processor is faster, smaller, and cheaper that previous-generation Neuron chips. The Neuron 5000
processor includes a fourth processor for interrupt service routine (ISR) processing.
The Neuron 5000 processor supports an internal system clock speed of 5 MHz to 80 MHz (using a 10
MHz external crystal). The Neuron 5000 processor includes 16KB of on-chip ROM to store the
Neuron firmware image and 64 KB on-chip RAM (44 KB is user-accessible). The Neuron 5000
processor requires at least 2KB of off-chip EEPROM to store configuration data, and you can use a
larger capacity EEPROM device or an additional flash device (up to 64KB) to store your application
code, configuration data, and an upgradable Neuron firmware image. The Neuron 5000 processor
supports the mapping of external non-volatile memory from 0x4000 to 0xDFFF in the Neuron address
space (a maximum of 42KB).
Neuron Assembler (NAS)
A Neuron C tool that is used to produce Neuron object files.
