2Introduction
2.1 RTU32M –The modular Brodersen RTU, PLC and Industrial Controller
The Brodersen RTU32M series is based on a 32-bit i.Mx6 ARM platform, providing a small footprint modular RTU and PLC with leading
edge functionality. As well as being a versatile RTU and PLC with flexible I/O designed to perform embedded data processing, control,
data logging and monitoring, it is also a networking communicator for collecting, managing and communicating data via protocols on
different physical interfaces upwards and downwards in an industrial environment.
Typical applications for the RTU32M are:
•Control and monitoring of water and waste water pump stations
•Substation automation applications
•Railway level crossing monitoring
•Communication Gateway applications between SCADA protocols –including Modbus, DNP3 and IEC60870.
The RTU32M hardware platform includes a 200-900MHz CPU with 128-256MB RAM and integrated 128MB NAND Flash. In addition, an
optional removable microSD Flash card (default is 4GB, supports up to 64GB), provides an easy to use portable access/upgrade option.
The integrated Flash stores the main RTU32 firmware including embedded Linux OS and your PLC runtime application. Standard drivers
like the Modbus Protocol Suite, IEC60870 or DNP3 are stored in the integrated NAND Flash. The removable microSD card can be used
for storing backup files and data logging files.
2.2 WebServer configuration and PLC programming in all IEC61131 languages
The RTU32M, like the other RTU32 Series of RTUs is configured via the integrated WebServer. Settings like LAN port addressing, time
functions and 3g/4g modem credentials are handled in webpages. Online monitoring of connected physical I/O and display of graphical
overviews is possible via webpages.
Programming of logic functions and configuration of communications drivers is managed using the Brodersen WorkSuite package
software. WorkSuite is a powerful tool that is used for configuration and programming of all RTU32 Series products. Applications
developed and running in the RTU32M will easily run directly on the other RTU32 Series products. The full suite WorkSuite software
package is included in the product package, and it will run in demo mode without any license (with some runtime restrictions).

3Getting Started
3.1 Configuration and default settings
The LAN interface on the RTU32M is set to its factory default settings at delivery:
LAN1: 192.168.0.1, Subnet: 255.255.255.0
You can use the LAN1 interface to configure the basic settings in the RTU32M. The basic settings include setup of network parameters
such as IP address, Subnet mask, default gateway, time settings, general username and password for accessing the web server pages
and file system with FTP etc.
The configuration is done via web pages in the RTU32M Web Server. You must use your normal web browser to setup the basic settings
for the RTU32M. The web pages are optimized for MS Internet Explorer, Firefox and Chrome. If you are experiencing problems with
using the latest MS Internet Explorer version, please enable Compatibility settings in the browser.
4How to connect and prepare your PC to configure the RTU32M
4.1 Wiring
Use a cross-wired or standard patch cable to connect your PC Ethernet interface to the LAN1 Ethernet interface of the RTU. Apply
power to the RTU –make sure that you connect the correct power supply voltage (24VDC).
4.2 Setting up your PC Ethernet driver (Windows)
Your PC Ethernet driver must be setup to work in the same network segment as the LAN interface on the RTU32 you use. You must
setup your PC Ethernet TCP/IP driver to work in the segment IP 192.168.0.x.
To setup the Ethernet driver select start –Settings –Network Connections –Local Area Connections and the following window will
appear:
Click on Internet Protocol 4 (TCP/IPv4), and click Properties. A new window for setting the PC IP address will appear. Set an IP address
in the same segment as the selected LAN IP address, for example 192.168.0.100 as shown here below.

4.4 RTU32M –Licensing
The RTU32M includes license options that manage the tag quantity and enable use of advanced drivers and options, hence some
restrictions may be imposed, including limiting the number of project variables, drivers and driver tags/data points. The System
Overview page includes information about the licensing, as shown in the example below.
The license limitations are managed by the firmware of the RTU32M. If you try to start a logic application in the RTU32M that exceeds
these limits, the project will NOT start and an info message in the Runtime info window in WorkSuite will indicate the status of the
limits in your project. Every time you start a runtime project the current status will be shown in the Runtime message window

and in the System Log of the RTU32M:
4.5 Adding Drivers and Runtime Options
The RTU32M Licensing interface allows loading and activation of runtime license options. The RTU ID is used by the Brodersen factory
to generate a unique license code that enables the required functionality. If you need additional drivers or other increased
functionality that requires a license upgrade, please contact Brodersen or your authorized distributor and provide them with the RTU
ID and details of the license requirements. You will then be sent a new license key that can be pasted in to the License Key field and
then select ‘Apply’ to activate the new license options. The example below shows a RTU32M licensed with many driver and
functionality options.

4.9 Runtime Settings - Main Settings
The Runtime settings menu allows adjustment of the PLC runtime setup.
4.9.1 Communication
Configuration of basic start-up settings, communication ports and enabling of Remote Access SProtocols. Hold the cursor over the small
icon and you will get online help.
Port (Main)
The Main port is used for Brodersen WorkSuite communication for configuration and debugging. Default setting is 502.
This port is also used for the ModbusTCP Server.
Port (Binding)
The Binding Port is used by the event based binding protocol, where two or more RTU32 and PC STRATON T5 runtimes can exchange
data. Default setting is 9000.
Port (Event log)
The Event Log port is where the RTU32M System Log can be viewed - either by connecting using telnet or the Brodersen Event Viewer
tool. Default setting is 911.
Enable Serial Remote Access Protocol (SP5)
This protocol is to be used for remote serial communication from the Brodersen WorkSuite and is particularly well adapted to
communication systems with severe constraints such as radios and modems. e.g. if you have the RTU32M placed on a remote site
connected via serial communication using multi-drop radio or line connection –or even dial connection, you are able to remotely
connect to the RTU32M with the Brodersen WorkSuite and work online as if it was on your workshop table. The speed will however be
slower depending on your actual serial communication speed. It is possible to attach this protocol to two communication ports.

Serial settings
The syntax is: [M]COM{n}:{b},{p},{d},{s}[,h][,LL] and the parameters in brackets [ ] are optional:
[M] Use modem connection
{n} Number of the COM port to be used (1 … 8)
{b} Allowed speeds: 300,600,1200,2400,4800,9600,19200,38400,57600,115200
{p} Parity: N,E,O (None,Even,Odd)
{d} Data bits: 7 or 8
{s} Stop bits: 1 or 2
[h] RTS/CTS handshaking where h is either RD,RE,RT:l:t or RC:l:t. In the COM port section you will find details of how to use these
parameters.
[LL] Log all bytes received and transmitted into the system log (port 911)
The following example shows setting for communicating on COM1 port, at 19200 baud, with Even parity, 8 data bits and 1 stop bit:
COM1:19200,E,8,1
Here a modem usage is enabled: MCOM2:9600,N,8,1
Here logging is enabled: COM1:9600,N,8,1,LL
Node address
Node Address (or Unit number) identifies the RTU32 on a multi drop network. The default number for RTU32M on a peer to peer
network is 1. The address must be a value from 1 to 32767.
Modem Init String
Here you enter the initialization string (AT commands) when using a modem.
RTU32M default is: AT E0 V0 &C1 S0=1
4.9.2 Start-up
The start-up option specifies how the PLC application is started when the RTU32M is powered up. The possible options are:
No Start –PLC application is NOT started when booting the RTU32.
Cold Start –PLC application is started without loading retained variables.
Warm Start –PLC application is started and retained variables are loaded (default) **.
Hot Restart –Only supported with battery backed RAM option and in Redundancy configuration!
** Note: RTU32M retained variables are stored to the SD card only if/when the ‘STORERETAIN’ function is called.
4.9.3 Options
Use UTC time for PLC real time functions
If enabled, it instructs all PLC real time functions (e.g. DTCurDate, DTCurTime and day_time) to return time in UTC. UTC time is not
adjusted according to daylight savings. If this parameter is disabled then time is returned in local time which is adjusted to daylight
saving if this option is enabled.
NOTE: Drivers that are implemented via PLC Functions –like the IEC60870 Driver –will use the PLC time stamp for events! Other
drivers may take standard windows time or whatever time is defined in the applicable standards.
Enable Multi Task
This is a licensed option and allows the RTU to run up to 4x independent logic tasks (global variables can be accessed from any/all
tasks).
PLC Main Settings / Binding Protocol Timing (seconds)
When using binding on slower network connection like some optical fibre modems or GPRS/3G wireless connections, you will need to
adjust the timing for the Binding driver.
The possible timing adjustments are:
Heartbeat period –how often a heartbeat is sending to check the binding link connection.
Binding Time-out –time-out on link check and general binding event.

4.12 System Configuration - Network Settings
On the System Configuration>Network Settings page you can change the LAN port settings to fit your local network. You can assign
fixed IP addresses or select DHCP to have the address set via a router. You can then gain access to the RTU32M with your browser,
SFTP client or Brodersen WorkSuite in your LAN network. If you do not know about the IP addresses and Subnet masks in your local
network, please contact your local network manager or IT department for help.
You can also change the RTU Host Name. The default host name of the RTU32M is imx6ul-var-dart.
After entering new settings, click Apply to save. Note that the new settings are activated within a few seconds (you do not need to
restart/reboot the RTU32M, or cycle power to the RTU).
4.13 Network Redundancy - Protocols
Modern substation automation systems use network redundancy to improve reliability and network changeover times. The RTU32M
System Configuration>Network Redundancy page allows selection of network redundancy protocols HSR (High Availability Seamless
Redundancy –where both LAN ports are used to ensure two network paths exist between adjacent nodes in a ring format), or PRP
(Parallel Redundancy Protocol –where both LAN ports are used to communicate via independent/separated networks).

4.14 Network Redundancy - Bonding
Network Bonding allows both RTU LAN ports to act as a single interface to allow primary/standby modes or load balancing in network
redundancy applications.
The four bonding modes include;
-Active- Backup
-Balance –RR
-Balance –XOR
-Broadcast
4.15 Adding a USB - Ethernet Adapter
The RTU32M supports addition of a USB Ethernet Adapter (Important, use only the Brodersen USB Ethernet adapter). After inserting
the USB Ethernet adapter, ETHERNET LAN 3 will be included on the Network Settings web page and it must be configured in the same
way as LAN 1 and LAN 2.
4.16 Adding USB –RS232 Serial Adapters
The RTU32M supports addition of USB Serial Adapters to add serial ports (Important, use only FTDI USB adapters). After inserting the
USB RS232 serial adapter, an additional com port will be created (eg. COM1 a /dev/ttyUSB1, then COM2 at /dev/ttyUSB2 etc.
4.17 Adding a USB - WiFi Adapter
The RTU32M supports addition of a USB WiFi Adapter to add an access point (default mode) or managed node (Important, use only
WLU6331 USB adapters). After inserting the USB Wifi adapter, ETHERNET LAN 3 will be included on the Network Settings web page.
The adapter can be disabled, configured and the mode changed from the Network Access Web page..

4.18 VPN Settings
The RTU VPN Client supports PPTP and L2TP (IPsec) for up to VPN Servers. The settings for each VPN server interface can be adjusted
using the webpage.
In order to ensure the VPN client is working you will need to enter all credentials correctly. The webpage includes small help icons - just
put the cursor on them and you will get details for each point. Controlling the connection of the VPN Client is done from the RTU logic
application. Use the Function Block ConnectVPN found in the Dial-up function group to manage the VPN connections
Note: the VPN page is disabled in the early release firmware
for the RTU32M (available 3Q 2018).
