BACK TO MENU

MS/TP Network Load

All Distech Controls’ devices are categorized as Masters and rated as ⅛ load

Other may have different network load ratings (for example, ¼, ½, or full load)

If a segment contains dissimilar device load ratings, the device with the highest load rating is the one that sets the limit for the maximum number of devices for that data bus segment

For example, you plan to put the following devices on one data bus segment:

10

The solution for the above example is to create two data bus segments connected together by a repeater and then split up the devices between the data bus segments.

BACK TO MENU

MS/TP Network Baud Rate

By default, the Distech BACnet controllers have their BAUD rate set to AUTO

The recommended baud rate for Distech Controls’ devices is 38.4 kbps

All devices on the data bus must be set to the same baud rate

Therefore, the chosen baud rate must be supported by all devices connected to the data bus

11

Baud Rate Support: from 9.6 to 76.8 kbpsRecommended: 38.4 kbpsDefault setting on ECB controllers: AUTO

Most devices will have a settings AUTO. This is the preferred setting for a controller. However, at least one controller on the BACnet MS/TP network data bus must have its BAUD rate set. The preference is to set the building controller’s BAUD rate (if present). e.g. on an EC-BOS.

BACK TO MENU

MS/TP Network Baud Rate

When the Baud rate is set to AUTO, the controller cannot initiate any communication until it has detected the baud rate of the BACnet MS/TP network

If all controllers on the BACnet MS/TP network are set to AUTO, then all controllers will not communicate

Setting the BAUD rate on at least one controller is required, which will set the BAUD rate for all other controllers on the data bus

Setting the BAUD rate on ECB controllers is performed with the EC-Smart-VueGeneral Configuration Menu (See Hardware Installation Guide)

Device Addressing / Best Practices

Device Instance (ID) Number

Bus Master Device Settings

Device MAC Addressing

Device Addressing Overview

Device Numbering System

BACK TO MENU


Each device connected to the BACnet MS/TP data bus is identified by a:

– MAC address

– Device Instance number

– Network number

The MS/TP Device MAC Address uniquely identifies a device on an MS/TP Network segment (identified by a Network Number). Devices on another MS/TP Network segment (identified by a different Network Number) can have the same MAC Address. The MAC Address is any number between 0 and 127 for Master devices, and 128 to 254 for Slave devices.

Address 255 is a wild card for broadcasts.

15

Addressing Both the MAC Address and the Device Instance must be set for each device and are essential for proper BACnet LAN operation

BACK TO MENU


The BACnet Device Instance (or Device ID) uniquely identifies a device across the complete BACnet internetwork. The Device Instance may be any number between 0 and 4194302. It is with the Device Instance that messages are exchanged between BACnet devices.

Unlike a MAC Address, a Device Instance cannot be reused elsewhere in the BACnet internetwork (it must be unique).

The BACnet Network Number is any number between 1 and 65534. A network number identifies a LAN for routing purposes. Each BACnet MS/TP Network will have a Network Number, and each BACnet IP Network will also have a Network Number.

16

Addressing Both the MAC Address and the Device Instance must be set for each device and are essential for proper BACnet LAN operation

BACK TO MENU

MS/TP Device MAC Address

Reserve some MAC Addresses for common commissioning and maintenance tasks.

– Reserve MAC 0 for the Building Controller MS/TP port

– Reserve MAC 1 for a portable router, so it can be temporarily connected without conflicting with other devices already connected to the data bus.

Avoid gaps in the MAC address sequence.

The physical order is unimportant.

MAC Addresses should be used as shown in the following table.

17BACK TO MENU

Setting MS/TP Device MAC Address

ECB devices:

– The MAC address can be changed using EC-Smart-Vue (all DIP switches need to be at 0 position)

– The MAC address can also be changed using DIPswitches on ECB-203 and higher series (device power cycle is required after)

ECB-STAT: On the LCD interface menu

EC-BOS: Using EC-NetAX Pro, MstpPort / Link Properties

18

Tool Kit All technicians should have an EC-Smart-Vue in their tool kit

Ex. MAC: 2+16+64 = 82

BACK TO MENU

MS/TP Bus Master – Device Settings

In a typical BACnet Network, the Network interface card used to access the MS/TP bus is called the Bus Master. In recommended architectures, the EC-BOS MS/TP Port is the Bus Master Device.

There are 4 configurations that are required on the Bus Master Device:

– Baud Rate

– MS/TP Address (MAC Address)

– Max Master

– Max Info Frames

19BACK TO MENU

MS/TP Bus Master – Baud Rate & MAC

The Baud Rate Usually set in the Bus Master (EC-BOS) and will be the only reference if all

devices on the network are set to AUTO. All devices on the network need to have the same Baud rate manually set or AUTO

– 38.4 kbps is the recommended Baud rate setting in the EC-BOS

– AUTO is the default and recommended setting for all ECB controllers

The MS/TP Address Or MAC Address for the Bus Master (EC-BOS) is set to 0 (it’s the default value)

20BACK TO MENU

MS/TP Bus Master – Max Master

MS/TP Network: Bus Master Device (Building Controller) To prevent the passing of the token to unused MAC Addresses situated after

the final Master device, the Max Master must be set in each Master Device.

About the Max Master Property By default, the Max Master for the MS/TP Bus is set to 127 in the EC-BOS

In practice, the actual number of devices connected to a data bus is far less. This gap unnecessarily slows-down the data bus.

Set the Max Master in the EC-BOS to the highest Master device’s MAC Address to optimize the efficiency of the data bus (reserve 3 to 5 more for spares)

21BACK TO MENU

MS/TP Bus Master – Max Info Frames

MS/TP Network: Bus Master Device (Building Controller)Max Info Frames is set to 20 (default) in the EC-BOS – may be increased as needed

Once a device has the token, it can make a number of information requests to other devices on the BACnet internetwork. The maximum number of requests is limited by the Max Info Frames property.

22

Device Type Info Frames Reason

ECB-STAT 1 Thermostats

ECB-VAV series 5 Terminal units controllers don’t have many requests

ECB-203 (and above) 5 System unit controllers have more requests

EC-BOS 20 Building Controllers have most requests

Ordinary BACnet MS/TP devices should have the Max Info Frames properties set to between 1 and 5. The Bus Master (EC-BOS) should have the Max Info Frames property set to about 20.

BACK TO MENU

BACnet Device Instance Number (ID)

Default Numbering System for Distech Controls’ controllers By default, controllers from Distech Controls automatically self-assign a Device

Instance number generated from the MAC Address assigned to the controller during installation.

The Device Instance number is calculated as follows, where 364 is Distech Controls BACnet manufacturer ID:

– Default Device Instance number = 364 X 1000 + MAC Address

This Numbering system is sufficient for a BACnet network that has only one MS/TP Network on only one Building Controller (EC-BOS).

Examples:

23

MAC Address Default Numbering System Default Device Instance Number

3 364000 + 3 364003

20 364000 + 20 364020

123 364000 + 123 364123

BACK TO MENU

BACnet Device Instance NumberFor Larger BACnet Networks

24

For larger BACnet networks that have more than one building controller, set the MAC addresses, Device Instance numbers and Network numbers manually according to a good well thought-out network planning scheme.

BACK TO MENU

Device Instance Numbering System

Numbering System for MAC Addresses, Device Instance and Network Numbers Distech recommends the following scheme, as it reuses the MAC Address and Network Number in the Device Instance number to make it easier to implement:

25

Discover Make sure to add only the devices connected to the MS/TP port of the specific EC-BOS being configured. Using this numbering system will greatly help to identify those devices that should be added to a given EC-BOS.

POWER SUPPLY REQUIREMENTS TOPIC 3

Power Supply Requirements

Power Supply Wiring

Power Supply Ground Lift

Typical Wiring Diagram

28BACK TO MENU

Power Supply Wiring

24V Power Supply wiring The 24V COM terminal of all devices must be connected to the Electrical System Ground.

Without this signal reference, transceivers may interpret the voltage levels of the differential data signals incorrectly, and this may result in data transmission errors.

All Distech devices use the 24V COM terminal as the signal reference point for the data bus. That wire must be connected to the Electrical System Ground at the power supply. This ensures that the 24V COM terminals of all devices in the building are at the same potential

Mechanical ground is unacceptable: Do not use a pipe, conduit or duct work for a ground

For inter-building connections, it is recommended to use a BACnet/IP or Fox network connection.

29BACK TO MENU


Avoid Ground Lift Ground lift is caused by wire resistance causing voltage drop on the power

wire run.

Because the 24V COM terminal is the signal reference point for the data bus, a ground lift would offsets that reference and affect the transceiver’s valid data levels.

If the ground lift (voltage drop) is more than 7 volts, there is a risk of data corruption and offline events due to the device being incapable of correctly reading data signals.

30BACK TO MENU


Techniques to Reduce Ground Lift Power wiring runs should not be too long, nor have too many devices

connected to it.

Use the instructions in the Hardware installation guide for limitations info.

Always use a transformer with 100VA power or less.

Power 5 devices or less with one 100VA transformer.

Use a wire with a gage of 18 or less for the power run.

When the total load of a number of device requires more than 100 VA, use two or more transformers.

Maintain consistent polarity when connecting controllers and peripherals to the power run.

The 24V COM terminal of the transformer must be connected to the building’s ground.
