BAScontrol22 – 22-point BACnet/IP Sedona Unitary Controller

The BAScontrol22 is a 22-point unitary controller
which supports BACnet/IP and Sedona
Framework using a 2-port Ethernet switch
connection. The controller complies with the

B-ASC device prole having a convenient mix of

8 universal inputs, 4 binary inputs, 4 analog
outputs and 6 relay outputs. Unique to the unit
are 48 web components which link Sedona wire
sheet readable/writeable data to web pages, and
24 virtual points which link Sedona wire sheet
readable/writeable data to a BACnet client. The

device is fully web page-congurable, and freely

programmable using Sedona’s drag-and-drop

programming methodology of assembling

components onto a wire sheet to create
applications. The unit can be programmed using
Niagara Workbench AX or a third-party Sedona
programming tool such as Sedona Application
Editor (SAE). Rugged design, low prole,
and wide temperature operation make it

suitable for indoor or outdoor use. To download
the free Sedona Application Editor, visit:

BAScontrol22 — Overview

Data Sheet – BAScontrol22

The BAScontrol22 utilizes a powerful 32-bit ARM7
processor with 512 kB of ash memory plus a 16 Mbit
serial ash le system for storing conguration data

and an application program.

By operating at the BACnet/IP level, the BAScontrol22
can share the same Ethernet network with
supervisory controllers and operator workstations.

The unit can be congured for a xed IP address or

can operate as a DHCP client receiving its IP address

from a DHCP server. A real-time clock with a super­cap backup allows for creating local schedules.

Universal Inputs

Eight input points can be congured — all discoverable as BACnet objects.

• Analog inputs: 0–10 VDC, 12-bit resolution, 0–20 mA (with external resistor)

• Temperature inputs: Type II or Type III 10 kΩ thermistors; 20 kΩ thermistor

• Resistance inputs: 1 kΩ to 100 kΩ

• Contact closure, voltage-free

• Pulse input accumulators (UI1–UI4): accommodates active or passive

sources (40 Hz max)

Via a 10/100 Mbps Ethernet switch, the Ethernet
port supports protocols such as BACnet/IP,

Sedona SOX, HTTP and FTP. Conguration of

universal inputs and virtual points can be
accomplished using web pages. Type II and type III
10 kΩ thermistor curves and a 20 kΩ thermistor
curve are resident in the unit. Current inputs can be

measured using external resistors. Contact closures
require a voltage-free source. Binary inputs and

outputs as well as analog outputs require no

conguration. The unit is powered from either a

24VAC/VDC source.

Binary Inputs

Four points of voltage-free contact

closure

Power Input

Web Page Conguration — Main Page and System

Access to the web pages is intended for the installer or
skilled technicians. In order to access any of the web
pages authentication is required. The default IP address
is 192.68.92.68 and the default User Name and

Password is admin/admin. Once on the main page, the

System Conguration button can be clicked.

The main web page provides an overview of all real
points plus access to other web pages. To congure a

point, click on the point and a conguration page will
appear. To observe the updated data for each point,
click Auto Refresh button to ON. Point values can be
temporarily forced by checking the box adjacent to the
point and entering a value into the point’s text box
(make sure Auto Refresh button is OFF). The value will
remain forced until the box is unchecked or the unit
power cycled. Care must be exercised when forcing

values into points.

The IP settings can be changed to the
desired values. Either DHCP or a static IP

address can be selected. If a static address is

desired, enter the value along with the

network mask and gateway address. If

domain address is required, enter in the
Primary and Secondary DNS addresses.

BACnet device data must be entered when
using BACnet. Make sure the Device Instance

and Device Object Name are both unique over

the complete BACnet Internetwork.

Either BACnet or Sedona protocols or both can
be selected.

Web Page Conguration — Channel, Time and Web Components

The BAS Channel should be congured rst.
Universal inputs must rst be dened which may
lead to more requests for information. Once the BAS
Channel is congured, the BACnet Object
Conguration can be accomplished. Although the
BACnet Object Instance is predened, the Object

Name can be entered and Units can be selected with

the drop-down. The COV Increment can be specied
for those channels intended for COV reporting by the

BACnet client device.

Separate web pages allow for
the conguration of up to 48 web

components. Web components
provide a means to write and

read data to and from Sedona
wire sheets without the need of a

Workbench tool. A web

component congured as a wire

sheet input can have its input
range restricted to minimum and

maximum values eliminating the

need to add limit detection within
the wire sheet logic. Web

components are ideal for
simplied control logic
conguration.

Time and date can be set manually or with the help of
a NTP server if access to the Internet is possible.

Daylight Savings Time can also be supported.

Manually-set time is backed up for seven days through
the use of a supercap in the event of power loss. If

accessing an NTP server using domain names, make

sure the DNS servers are specied in the System
Conguration screen.

Time is backed up for seven days through the use of a

super-cap.
