Neuron Chip Local Operating Network LSIs

Local Operating Network(LON) are low cost, reliable, intelligent local network systems that facilitate communication between sensors and actuators (among a maximum of 32,385 nodes) (see Figure 1). LonWorks technology does not require the dedicated communications networking technology nor special communications protocols of LANs. In contrast, LonWorks can be developed into high-level networks simply by defining the functions to be performed at each node. Moreover, the special architecture of LonWorks systems means that, when reconfiguring an existing network or even changing its functions, the network itself can be used to modify the configuration data or to load programs, etc. Nodes can also be added or removed as required. Figure 2 shows the typical structure of a LonWorks node.

LonWorks System Features

LonWorks technology is a completely new network control system concept developed by Echelon Corporation, USA. The key feature of LonWorks technology is the incorporation of the communications programs in the LonWorks LSI (Neuron® Chip) as firmware (internal LonTalk®). This means that, by using LonWorks, the programs to handle the communication protolcol in communication network systems no longer need be provided by the user. Refer to pages 8 and 9 for details of the LonTalk® protocol. A special version of the C programming language (Neuron® C) is used to reduce the load involved in developing application programs. See page 5 for the features of Neuron® C.The Neuron® Chip has eleven I/O ports which are equipped with the firmware programmable function I/O facility. For example, available features include measurement of an input signal on time (Ontime input) or Triac output suitable for adjusting the intensity of an electric light (see Table 1 to 5). Users can avoid complex program development by selecting the appropriate function I/O facility for each node.

Neuron® C Programming

1. Objects for I/O functionsAll I/O functions can be used simply by selecting the desired I/O object (see Table on page 4) and declaring the object for the I/O pin to be used.

Example: To use pin IO0 for bit input, make the following declaration:

IO_0 input bit Switch;

You can also use the io_in( ) and io_out( ) functions in programs.

2. Automation of network communication protocol (network variables)To expedite packet communications, Neuron® C includes special network variables.As with normal variables, type declaration (int, or unsigned long, etc.) is required, but input or output is specified at the same time.

Example: To declare an int type output network variable, declare the following:

network output int NV_switch_state;

The processing associated with this communications protocol is in firmware and no special code needs to be included in the application program. Messages can be automatically output to the network by assigning a value to a declared output network variable in the application program. Also, if you receive a message, the value of the declared input network variable is automatically updated. the nv_update_occurs( ) event is provided for checking for the automatic updating of input network variables.

3. Event driven schedulerThere is an inbuilt round-robin type scheduler (which does not use the main( ) function) which immediately executes the appropriate task when an event occurs.The event is evaluated in the when clause, and the appropriate task is then executed.

An example program listing is shown on next page.

Standard Network Variable Types (SNVTs)

For overall network program development, it is worthwhile considering the function to be performed at each individual node's I/O ports. For this reason, data required form the network can be logically connected to the network simply by issuing an input command with a network variable (see Table 6). If transmission across the network of data or information read form the I/O port is required, it can be logically connected to the network simply be issuing an output command with a network variable (SNVTs). These logical connections can be performed by binding across the network after the node has been configured. Optional data other than network variables can also be transmitted in packets. A maximum of 228 bytes per packet can be inserted and manipulated by the user as required. Consequently, in a LonWorks system, individual nodes can be developed using object-oriented programming and expanded to form a network with high overall performance.

The LonTalk® Protocol

The LonTalk® protocol, which supports a wide range of applications, is designed to support all communications on the LonWorks network. Examples include electronic home appliances, factory automation equipment, motor vehicle control equipment, building control equipment, and home automation equipment. The LonTalk® is a full 7-layer protocol as defined by the Open Systems Interconnection (OSI) reference model of the International Standards Organization (ISO) (see Table 7). Compatible with other LonWorks-based products. Communications data is transferred in relatively small packets, increasing network efficiency. Compatible with multiple media.

Table 7. LonTalk® Protocol Layers

LonTalk® Protocol Features

Multiple Media Support The following media are supproted by the LonTalk® protocol: Twisted pair (TP) Power line (PL) Radio frequency (RF) Infrared (IR) Coaxial cable (CX) Optical fiber (OF)

Table 8. Example of Transceiver Specifications

The above transceiver modules are marketed by Echelon Corp.

Support for Multiple Communications Channels

A channel consists of one transmission medium block (see Figure 3). A network consists of multiple channels. The interconnection of these channels is supported by devices called bridges and routers. Bridge: A bridge transfers all packets input from one channel to another channel. Router: A router determines the destination node address for a packet on a channel and decides whether or not to transfer the packet to a different channel. The intelligent router improves the communica- tions efficiency of a medium.

Improved Communications Response Times

The LonTalk® protocol uses a unique collision avoidance algorithm.The collision avoidance algorithm allows a channel to manifest its maximum transmission throughput without any deterioration due to excessive collision. In addition, collision detection is supported as an option for particular media, including twisted pair. Collision detection further improves the response time in the event of a collision. The LonTalk® protocol can support more than 500 transactions per second (in the case of 12 byte length), when the transmission rate is 1.25 Mbps using twisted pair.Although it may not be possible to slow down transmission for certain node applications, the LonTalk® protocol supports media access in which a priority rating can be set for each node (priority mode).Immediate access to the medium is guaranteed when the end of communication on that medium is detected at a node for which a priority rating has been established.

Improved Communications Reliability

The LonTalk® protocol supports an end-to end communications acknowledge mode auto with retry function.When a node sends a message in this mode to another node or a group node, the receiving node sends an acknowledgment to the sender when the message is received. If the sender does not receive the acknowledgment within a set time, it automatically resends the message. The number of retries can also be set.The "Request/Response" mode is an even more reliable communications mode. When a sending node requests a certain process to be performed by another node, the receiving node executes the process and returns the result to the sending node.

Improved Security

The LonTalk® protocol includes an "Authentication mode". In this mode, authentication is carried out between the nodes that are to communicate without complex encryption being performed. This mode prevents unauthorized network access without any reduction throughout.

Communications Compatibility of LON Products

Products that use the LonTalk protocol are designed for mutual communications control even with the products of other manufacturers. The Standard Network Variable Type (SNVTs) declaration statement in the LonTalk® protocol firmware defines the format of data transmitted by the communications packet and, by using the variable types of the particular network, enables communications with other products using the same declaration statement without the tedium of developing communications protocols.

Network Management Service

The LonTalk® network management service is the heart of the LonTalk® protocol. Support for this service is built into every LonWorks®

node. Thus, irrespective of its location, every node can respond to LonTalk® commands from nodes that have been specified for executing the network management function. The following lists some of the services supported by network management messages. Find unconfigured nodes and download network address Stop, start, and reset node applications Access node communications statistics Configure routers and bridges Download new application programs To ensure security, authoriy can be specilied as a condition for network management messages irrespective of application messages.

Extract topology of active network

Modify network variable configuration table. The table contains information on the protocol service type used for sending the network variables and whether the authentication serviceis in use or to send the variables to a priority slot.

Neuron® Chip Communication Ports

The TMPN3150 and TMPN3120 have five dedicated communication ports, allowing them to be configured for communications with each type of medium. Table 9 shows the communication port conditions.

The TMPN3120B1AM/E1M have 10 Kbytes and the TMPN3120A20M/A20U/FE3M/FE5M has 16 Kbytes of incorporate ROM enabling the construction of single chip systems. This ROM is preloaded with firmware such as the protocol and application library, supporting many kinds of applications. The TMPN3150B1AF does not incorporate ROM and is configured to access external memory (58 Kbytes max of which 42 Kbytes can be used for application programs). This makes the TMPN3150B1AF suitable for more complex applications. Through the combination of its unique hardware and firmware, the Neuron Chip contains all the key functions required for a LonWorks node. Processes all LonTalk® protocol messages. Includes input pin functions for detection and output pin functions for detailed operation of output devices. Includes a library of application functions (see Tables 1 to 5). Installation parameters are stored in non-volatile memory.These functions minimize the number of external components required to construct a LonWorks network, resulting in a low overall cost. Figures 9, 10 and 11 show the pin assignment of TOSHIBA Neuron Chip.

The service pin supports the following functions, convenient for network installation and maintenance. Setting the service pin low transmits the Neuron® ID and program name on the network. That information is used at the following times.

To communicate with a node that does not have network configuration information.

To find out the program name.

An LED can be connected to the service pin to indicate the status of the node. Lit: The node has no valid application code.

Blinks at 1/2 Hz rate: The node has application code but no network configuration information.

Not lit: The node has both application code and network configuration information.

To access these input/output functions, the service pin is multiplexed between input and output by turning the N-ch open drain output ON/OFF at 76 Hz with a 50% duty cycle.

Figure 12. Input/Output Waveforms and Circuit for Service Pin

The Neuron chip incorporates a low-voltage detector

circuit. When using this circuit in conjunction with an

external circuit, the external circuit may require an

open-collector or open-drain low-voltage detector

circuit. The external LVD must be used if Neuron® chip operated at 20MHz.

The reset pin has an open-drain output with an active-low input, and an internal pull-up resistor. When the reset pin is held at 0.8 V or below for at least 20 ns, the reset operation begins.The reset pin can be activated by a software reset or by output from a watchdog timer. Accordingly, this reset pin can be also reset external circuits such as a transceiver.
