Figure 2: Example of LON communication structure for a substation automation

system

An optical network can be used within the substation automation system. This enables

communication with the IEDs through the LON bus from the operator’s workplace, from the

control center and also from other IEDs via bay-to-bay horizontal communication. For LON

communication an SLM card should be ordered for the IEDs.

The fiber optic LON bus is implemented using either glass core or plastic core fiber optic

cables.

2.1.1 The LON Protocol

M14804-32 v2

The LON protocol is specified in the LonTalkProtocol Specification Version 3 from Echelon

Corporation. This protocol is designed for communication in control networks and is a peer-

to-peer protocol where all the devices connected to the network can communicate with each

1MRK 511 395-UEN E Section 2

LON application

LON, 670 series 9

Communication protocol manual

other directly. For more information of the bay-to-bay communication, refer to the section

Multiple command function.

2.1.2 Hardware and software modules

M14804-35 v5

The hardware needed for applying LON communication depends on the application, but one

very central unit needed is the LON Star Coupler and optical fibers connecting the star coupler

to the IEDs. To interface the IEDs from the MicroSCADA with Classic Monitor, application

library LIB520 is required.

The HV Control 670 software module is included in the LIB520 high-voltage process package,

which is a part of the Application Software Library in MicroSCADA applications.

The HV Control 670 software module is used for control functions in the IEDs. The module

contains a process picture, dialogues and a tool to generate a process database for the

control application in MicroSCADA.

When using MicroSCADA Monitor Pro instead of the Classic Monitor, SA LIB is used together

with 670 series Object Type files.

The HV Control 670 software module and 670 series Object Type files are used

with both 650 and 670 series IEDs.

Use the LON Network Tool (LNT) to set the LON communication. This is a software tool

applied as one node on the LON bus. To communicate via LON, the IEDs need to know

• The node addresses of the other connected IEDs.

• The network variable selectors to be used.

This is organized by LNT.

The node address is transferred to LNT via the local HMI by setting the parameter

ServicePinMsg

=

Yes

. The node address is sent to LNT via the LON bus, or LNT can scan the

network for new nodes.

The communication speed of the LON bus is set to the default of 1.25 Mbit/s. This can be

changed by LNT.

Communication protocol manual

Section 3 LON operation principle

3.1 Operation principle

IP14439-1 v2

M15083-3 v3

The speed of the network depends on the medium and transceiver design. With protection and

control devices, fiber optic media is used, which enables the use of the maximum speed of 1.25

Mbits/s. The protocol is a peer-to-peer protocol where all the devices connected to the

network can communicate with each other. The own subnet and node number are identifying

the nodes (max. 255 subnets, 127 nodes per one subnet).

The LON bus links the different parts of the protection and control system. The measured

values, status information, and event information are spontaneously sent to the higher-level

devices. The higher-level devices can read and write memorized values, setting values, and

other parameter data when required. The LON bus also enables the bay level devices to

communicate with each other to deliver, for example, interlocking information among the

terminals without the need of a bus master.

The LonTalk protocol supports two types of application layer objects: network variables and

explicit messages. Network variables are used to deliver short messages, such as measuring

values, status information, and interlocking/blocking signals. Explicit messages are used to

transfer longer pieces of information, such as events and explicit read and write messages to

access device data.

The benefits achieved from using the LON bus in protection and control systems include direct

communication among all terminals in the system and support for multi-master

implementations. The LON bus also has an open concept, so that the terminals can

communicate with external devices using the same standard of network variables.

3.1.1 LON protocol

M15083-11 v1

3.1.1.1 Configuration of LON

M15083-13 v3

LON network tool (LNT) is a multi-purpose tool for LonWorks network configuration. All the

functions required for setting up and configuring a LonWorks network, is easily accessible on a

single tool program.

3.1.1.2 Activate LON Communication

M15083-16 v3

Activate LON communication in the Parameter Setting tool under Main Menu/Configuration/

Communication/Station communication/ LON/HORZCOMM:1, where

Operation

must be set

to

ON

.

3.1.1.3 Add LON Device Types LNT

M15083-19 v3

A new device is added to LON Network Tool from the Device menu or by installing the device

from the ABB LON Device Types package for LNT 505 using SLDT package version 1p2 r04.

LON operation principle

LON, 670 series 11

Communication protocol manual

3.1.1.4 LON net address

M15083-22 v3

To establish a LON connection, the IED has to be given a unique net address. The net address

consists of a subnet and node number. This is accomplished with the LON Network Tool by

creating one device for each IED.

3.1.2 Vertical communication

M15083-25 v1

Vertical communication describes communication between the monitoring devices and

protection and control IEDs. This communication includes sending of changed process data to

monitoring devices as events and transfer of commands, parameter data and disturbance

recorder files. This communication is implemented using explicit messages.

3.1.2.1 Events and indications

M15083-28 v3

Events are sent to the monitoring devices using explicit messages (message code 44H) with

unacknowledged transport service of the LonTalk protocol. When a signal is changed in the

IED, one message with the value, quality and time is transmitted from terminal.

Binary events

M15083-31 v6

Binary events are generated in Event function blocks EVENT:1 to EVENT:20 in the IEDs. The

EVENT function blocks have predefined LON addresses. Table

2 shows the LON addresses to

the first input on the EVENT function blocks. Addresses to the other inputs on the EVENT

function block are consecutive after the first input. For example, input 15 on EVENT:17 function

block has the address 1280 + 14 (15-1) = 1294.

For double indications, only the first eight inputs 1–8 must be used. Inputs 9–16 can be used

for other types of events at the same EVENT block.

Three EVENT function blocks EVENT:1 to EVENT:3 running with a fast loop time (3 ms) are

available as basic in the IEDs.. The remaining EVENT function blocks EVENT:4 to EVENT:9 run

with a loop time of 8 ms and EVENT:10 to EVENT:20 run with a loop time of 100 ms. The EVENT

blocks are used to send binary signals, integers, real time values like analogue data from

measuring functions and mA input modules as well as pulse counter signals.

16 pulse counter value function blocks PCFCNT:1 to PCFCNT:16, and 24 mA input service values

function blocks SMMI1_In1 to 6 – SMMI4_In1 to 6 are available in the IEDs.

The first LON address in every EVENT function block is found in table

2. The formula for

calculating the LON address is:

LON Address = (EVBlkNr-1)×16 + signalNr +1023

For instance, the first pin at Event block number 2 has the address:

(2-1)×16 +1 +1023 = 1040

Event masks

M15083-78 v4

Event mask for each input can be set individually from Parameter Setting Tool (PST) under:

Settings/IED settings/ Monitoring / Event Function or via parameter setting tool (PST) as

follows:

• No events

• OnSet, at pick-up of the signal

• OnReset, at drop-out of the signal

• OnChange, at both pick-up and drop-out of the signal

• AutoDetect, the EVENT function makes the reporting decision (reporting criteria for

integers has no semantic, prefer to be set by the user)

Single indication

M15083-123 v3

Directly connected binary IO signal via binary input function block (SMBI) is always reported on

change, no changed detection is done in the EVENT function block. Other Boolean signals, for

example a start or a trip signal from a protection function is event masked in the EVENT

function block.

Double indications

M15083-126 v3

Double indications can only be reported for the first 8 inputs on an EVENT function block.

• 00 generates an intermediate event with the read status 0

• 01 generates an open event with the read status 1

• 10 generates a close event with the read status 2

• 11 generates an undefined event with the read status 3

Analog value

M15083-135 v4

All analog values are reported cyclic. The reporting interval is taken from the connected

function if there is a limit supervised signal. Otherwise it is taken from the EVENT function

block.

3.1.2.2 Command handling

M15083-80 v4

Commands are transferred using transparent SPA-bus messages. The transparent SPA-bus

message is an explicit LON message which contains an ASCII character message following the

1MRK 511 395-UEN E Section 3

LON operation principle

LON, 670 series 13

Communication protocol manual

coding rules of the SPA-bus protocol. The message is sent using explicit messages with

message code 41H and using acknowledged transport service.

Both the SPA-bus command messages (R or W) and the reply messages (D, A or N) are sent

using the same message code. It is mandatory that one device sends out only one SPA-bus
