2. The Modbus Interface Module
2.1 Description
The BSL-330 module is an RS-232/422/485 interface module used to
interface various PLC equipment (Programmable Logic Controllers) to
the AutroSafe Interactive Fire Alarm System. The module is both a
physical and a logic protocol converter. At the physical connection
level, it transforms an RS232 connection to an RS485 or RS422
connection. This is convenient as this type of connection is safer in
noisy environments.
The module is connected to the AutroSafe via the AutroCom protocol.
It communicates with both protocols by means of the conversion
software.
A master Modbus device polls the BSL-330 module for reading its
registers. It expects a response within a defined time period.
Communication can be over various serial mediums. The one used
here is the MODBUS RTU protocol over an RS485 link. The
communication is set at 9600 baud, 8 data bits, 1 stop bits and no
parity.
The BSL-330 module allows:
• detector statuses on the AutroSafe to be made available to a
Modbus PLC
• users to send basic commands to the AutroSafe from a Modbus
PLC
The Modbus PLC acts as “master” to the BSL-330, and the AutroSafe
as “slave” to the BSL-330. The AutroSafe appears to the Modbus PLC
as a Modbus slave.
For information on Communication, refer to section 5.3.1.
The BSL-330 module has the following features:
• DIN-rail enclosure with removable screw terminals; fits 35mm
symmetric rails
• DC power input in the range +7V to +35V; uses a high efficiency
switching power supply
• Two serial ports: Port 1 and Port 2; isolated from each other and
from the power supply
• Port 1 is RS-232; Port 2 is RS-422/485
• Controlled slew rate drivers on RS-422/485 ports - no terminators
needed for cables shorter than 300m
• Internal pull-up/pull-down resistors on RS-422/485 ports ensure
that RS485 bus floats to a valid state when not driven

3.4 Entering Executive Mode
The BSL-330 module must be electronically configured before it can
be used. Configuration must be done via Port 1, which has to be set to
Executive Mode.
• To enter Executive Mode, press and hold down the green
Executive Mode button on the front panel approximately 5 seconds
until the EXE indicator starts blinking, then release it.
A few seconds later (approximately 3-4 seconds), the red EXE

3.5 Setting Parameters / Configuration Program
The parameter settings for Port 1 (AutroSafe) and Port 2 (PLC) are
done by means of the KD485 Configuration Program, which is
delivered with the BSL-330 module.
• Make sure that the BSL-330 module is in Executive Mode. The
EXE indicator should be blinking rapidly. If not, communication is
not established, and you must repeat the procedure described in
the previous section (Entering Executive Mode).
• Insert the floppy disc into your harddisk drive.
• Dobbelclick on the installation icon, and the Configuration Menu will
appear on screen.
• Set the baud rate for Port 1 (AutroSafe) to 9 600 baud, 8 bits,
1 stopbit, even parity (which is the default setup of AutroSafe).
Note that these parameters can be changed for AutroSafe by
means of the AutroSafe Configuration Tool.
• Choose RX Xon/Xoff disabled (the Xon/Xoff characters to control
data being received on Port 1)
• Choose TX Xon/Xoff disabled (the Xon/Xoff characters received by
BSL-330 control transmitted data on Port 1).
• Set the appropriate parameters for Port 2 (external PLC
equipment) according to the PLC requirement.
• Click on the highlighted button marked Update KD485 and the
message Writing new KD485 Configuration will appear on screen.
When the message disappears, and the Update KD485 button no
longer is highlighted, all parameters have been set and the
configuration is completed.

• Simply, snap the BSL-330 module onto the DIN rail inside the
AutroSafe Fire Alarm Control Panel BS-320.
NOTE:
If the BSL-330 module is to be removed from the rail, gently lift the front end upwards.
If necessary, use a flat screwdriver to open up the DIN rail clip. Note that very little
force is required.
DIN rail clip
For ventilation purposes, make sure that there is a free space
of minimum 50 mm above and below the BSL-330 module after
it has been rail-mounted inside the cabinet.

4.3 Connecting the RS-232 Serial Interface Cable
The drawing below gives an overview of the cable connections.
As shown on the drawing, Port 1 is used for the cable connection from
AutroSafe, while Port 2 is used for the connection to the external PLC
equipment.
• Consult the cable overview drawing below.
• Connect the cable from the Serial Port Interface Board
EAU-321 (inside the AutroSafe BS-320) to the connector (Port 1)
on the BSL-330 module.
• Continue following the step-by-step procedure described in the next
section Commissioning.
4.4 Overview - Cable Connections
The drawing below gives an overview of the required cable
connections.
If the BSL-330 module is placed outside the AutroSafe

5. Commissioning
5.1 Overview
The site-specific AutroSafe configuration data and the BSL-330
register mapping (Modbus register, see Modbus Register Mapping)
are used as input for the configuration of the external PLC equipment,
which is to be considered as the master modbus device.
The BSL-330 module reads all status messages from AutroSafe on a
protocol called AutroCom, and keeps the accumulated results in a list
of registers internally.
The PLC polls the BSL-330 module for reading its registers. It expects
a response within a defined time period. Communications can be over
various serial mediums. The one used here is the MODBUS RTU
protocol over an RS485 link.
The PLC takes action on some (or all) of the status messages from
AutroSafe.
The illustration below gives an overview of the data communication.

5.2 Step-by-step Procedure
The commissioning of the BSL-330 module includes the following
steps:
Step ✔
1 Complete the site-specific AutroSafe configuation by means of the AutroSafe
Configuration Tool, including:
- List of detectors / alarm points
- Cause / effect
- AutroCOM port settings (refer to Setting Parameters / Configuration Program)
- List of panels
- List of other devices
2 Download the Configuration files to AutroSafe.
3 Install and connect the BSL-330 module as described in the previous section.
4 Power up the BSL-330 module - connect the cable from the 24V DC power source
to the connector (Port 1) on the BSL-330 module (refer to the cable connections
overview on the previous page).
5 Verify that the BSL-330 module is properly connected to AutroSafe and that
connection is established.
The 1RX and 1TX indicators should blink at least every 8 seconds.
6 Complete the site-specific PLC configuration, including:
- Cause / effect
- Modbus Register Map versus AutroSafe Unit IO's (from AutroSafe
configuration file "Installation \ UnitName.txt")
- BSL-330 module port 2 settings (refer to Setting Parameters /
Configuration Program)
7 Do the necessary connections between the external PLC equipment and the
connector (Port 2) on the BSL-330 module.
8 Verify that the BSL-330 module is properly connected to the PLC and that
connection is established.
The 2RX and 2TX indicators should blink at least every 3 seconds.The exact
interval will depend on the PLC's polling period.
9 Verify all critical functions.
