CPU Backup Battery
The CPU/System Controller board has a coin cell socket that accepts a
3.0V, 300 mA-hr lithium battery. This 3.0V battery provides backup
power for the real-time clock and the system’s Static RAM (SRAM).
CPU Memory
There are several different types of memory used by the CPU:
Boot/Downloader FLASH
Boot/download code is contained in a single 512 Kbyte FLASH chip.
Boot FLASH also holds the value of soft switches, audit/archive file
configurations, and user account and port information.
The ControlWave Express includes 8 MB of FLASH memory. The
FLASH memory holds the system firmware and the boot project.
Optionally FLASH memory also stores the zipped ControlWave project
(*.zwt), user files, and historical data (audit/archive files).The FLASH
does not support hardware write protection.
System Memory (SRAM)
The ControlWave Express has 2 MB of static random access memory
(SRAM). During power loss periods, SRAM enters data retention mode
(powered by a backup 3.0V lithium battery). Critical system information
that must be retained during power outages or when the system has been
disabled for maintenance is stored here. This includes the last states of
all I/O points, audit/archive historical data (if not stored in FLASH), the
values of any variables marked RETAIN, the values of any variables
assigned to the static memory area, and any pending alarm messages not
yet reported.
1.4 Power Options
1.5 I/O Options
You can power the ControlWave Express by:
a user supplied rechargeable 6/12V lead acid battery (used in
conjunction with a solar panel),
other user-supplied battery systems
bulk (nominal +6Vdc, +12Vdc or +24Vdc) power supply.
If you connect solar panels to rechargeable battery systems to power the
ControlWave Express, there is a secondary power input you can use to
provide power if there is no power from the solar panel/battery system.
ControlWave Express comes with the following standard I/O
2 Pulse Counter Inputs with a 1 second scan rate (can be configured
as discrete inputs (DI))
The 14 MHz CPU and 33 MHz CPU with Ethernet also include a
Resistance Temperature Device (RTD) probe.
In addition, three different versions of the optional process I/O board are
available:
The ControlWave programming environment consists of a set of
integrated software tools which allow you to create, test, implement,
and download complex control strategies for use with the ControlWave
Express. Figure 1-2 graphically presents the programming environment.
Figure 1-2. ControlWave Programming Environment
The tools which make up the programming environment include:
ControlWave Designer is your load-building package. It offers
1-6 Introduction Revised Mar-2011
several different methods for you to create control strategy programs
that run in your ControlWave Express. You can use pre-made
function blocks, ladder logic, or structured languages. The resulting
process control strategy programs (called projects) are fully
compatible with IEC 61131 standards. For information on
ControlWave Designer, see the Getting Started with ControlWave
Designer manual (document D5085), and the ControlWave
Designer Programmer’s Handbook (document D5125).
The I/O Configurator, accessible via a menu item in ControlWave
Designer, allows you to define process I/O in the ControlWave and
configure the individual mapping of I/O points for discrete and
analog inputs and outputs. For information on the I/O Configurator
see the ControlWave Designer Programmer’s Handbook (document
D5125).
The ACCOL3 Firmware Library, available within ControlWave
Designer, includes a series of ControlWave-specific function blocks.
These pre-programmed function blocks let you accomplish various
tasks common to most user applications including alarming,
historical data storage, as well as process control algorithms such as
PID control. For information on individual function blocks, see the
online help within ControlWave Designer.
OpenBSI Utilities provides a set of programs that allow you to
configure a communication network of ControlWave controllers,
download files to the controllers, and collect data from the network.
OpenBSI also exports data from the network to a SCADA/host
package, such as OpenEnterprise. For information on configuring
OpenBSI communications, see the OpenBSI Utilities Manual
(document D5081).
OpenBSIHarvester is a special add-on package that allows
scheduled data collections from large networks. For information on
the Harvester, see the OpenBSI Harvester Manual (document
D5120).
A series of web page controls are available for retrieval of real-time
data values and communication statistics. These controls utilize
ActiveX technology and are called through a set of fixed web pages,
compatible with Microsoft® Internet Explorer. Alternatively,
developers can place the controls in third-party ActiveX compatible
containers such as Visual BASIC or Microsoft® Excel. For
information on the ActiveX controls, see the Web_BSI Manual
(document D5087).
User-defined web pages - If desired, you can use the ActiveX web
controls in your own user-defined web pages you can store at the PC
to provide a customized human-machine interface (HMI).

Getting Started with ControlWave Designer Manual (D5085)
and the ControlWave Designer Programmer’s Handbook
(D5125) for material related to software installation and use.
2.2.1 Unpacking Components
Packaging
Depending upon how you order it, the ControlWave Express may
arrive pre-assembled, or in a number of separate boxes. If you did not
order it pre-assembled, you must identify, unpack, and assemble the
components. These include:
ControlWave Express enclosure / mounting chassis
CPU/System Controller board and Process I/O board (one assembly)
The ControlWave Express enclosure does not include a ground lug.
Instead, you must use one or more of the mounting screws to secure a
ground cable to the unit. Once you have installed the unit, run a ground
wire (#4 AWG max wire size) between one of the mounting screws for
the enclosure to a known good earth ground. For more information on
grounding see the ControlWave Grounding Supplement (S1400CW):
Additional grounding guidelines include:
Use stranded copper wire (#4 AWG) to earth ground, and keep the
length as short as possible.
Clamp or braze the ground wire to the ground bed conductor
(typically a stranded copper AWG 0000 cable installed vertically or
horizontally).
Using a high-wattage soldering iron, crimp and solder the wire end
you will fasten to the ControlWave Express to a terminal ring/lug.
Run the ground wire so that any routing bend in the cable has a
minimum radius of 12-inches below ground and 8-inches above
ground.
2.3.1 Setting DIP Switches on the CPU/System Controller Board
Before you install the CPU/System Controller board, you must
determine the settings for three banks of DIP switches. Refer to Figure
2-3 for the location of the DIP switch banks. Refer to Tables 2-1, 2-2,
and 2-3 for an explanation of the DIP switch positions.
Note: Examine each bank of DIP switches carefully to note the switch
direction for ON or OFF.

2.3.3 General Wiring Guidelines
ControlWave Express terminal blocks use compression-type
terminals that accommodate up to #16 AWG wire.
When making a connection, insert the bare end of the wire (approx
¼” max) into the clamp adjacent to the screw and secure the screw.
To prevent shorts, ensure that no bare wire is exposed. If using
standard wire, tin the bare end with solder to prevent flattening and
improve conductivity.
Allow some slack in the wire while making terminal connections.
Slack makes the wires more manageable and helps minimize
mechanical strain on the terminal blocks.
2.3.4 Wiring Power to the CPU/System Controller Board
Caution
At this time you can connect power wiring. However; for safety reasons
and to prevent accidental damage to your bulk DC power supply, do not
connect the pluggable terminal block connectors TB1 and TB2 to the
CPU/System Controller board until after you install, wire, ground, and
configure the entire unit.
Follow the instructions in Section 2.3.3 General Wiring Guidelines wh
wiring connections.
Depending upon the CPU type, the ControlWave Express accepts either
a 6Vdc, 12Vdc or 24Vdc bulk power input. You can estimate the
maximum current required for your ControlWave Express using the
following equation:
Bulk +6/12/24 Vdc Supply Current = CPU/System Controller Board (with
Refer to Table 2-4 for ControlWave Express power requirements based
on the CPU type.
Table 2-4. ControlWave Express Bulk Power Requirements
CPU Type and Components
14 MHz Ultra Low Power CPU with LCD
display/keypad
33 MHz Low Power CPUwithout Ethernet, but with LCD display/keypad
Note: If your ControlWave Express includes an external modem or
radio, contact the radio/modem manufacturer for power
consumption specifications.
If your ControlWave Express is configured to use a solar panel to charge
a 7AH (6V or 12V) battery for power, NEVER CONNECT THE SOLAR
PANEL/CHARGER WITHOUT ALSO CONNECTING THE BATTERY.
Connections without the battery present can damage power supply
components.
Unplug removable connector TB1 from the CPU/System Controller
board. We recommend you do not plug the connector back into the CPU
until the unit is already installed in the housing.
You can power the ControlWave Express using a bulk DC power supply
using connections TB1-3 and TB1-4.
Nominal input source operating ranges for the DC power supply are:
+6Vdc (+5.4Vdc to +16.0Vdc nominal operating range)
+12Vdc (+11.4Vdc to +16.0Vdc nominal operating range)
+24Vdc (+21.8Vdc to +28.0Vdc nominal operating range)
Not all ControlWave Express CPUs support all DC power supplies.
Supported options are:
14MHz Ultra Low Power CPU: Supports +6Vdc or +12Vdc
nominal power supply.
33MHz Low Power CPU: Supports +12Vdc nominal or +24Vdc
nominal power supply.
33MHz CPU with Ethernet: Supports +12Vdc nominal or +24Vdc
nominal power supply.
Alternatively, you can power low powered versions of the ControlWave
Express using a solar panel connected to a user-supplied rechargeable
7AH (6V/12V) lead acid battery at connections TB1-1 and TB1-2.
TB1 connections are:
TB1-1: (Solar Power IN+): Power from a 1W – 6V, 5W – 6V or
5W – 12V solar panel (internally wired to recharge a user-supplied
battery). Not available on units with Ethernet.
TB1-2 = Ground (GND)
TB1-3 = Primary Power: Power from a user-supplied nominal
+6Vdc , +12Vdc or +24Vdc power supply, depending upon the
CPU type.
TB1-4 = Ground (GND)
TB1-5 = Auxiliary Power Out+: for an external radio or modem (if
supported). Not available on units with Ethernet.
TB1-6 = Ground (GND) for Aux power out.
Figure 2-4 shows the typical wiring at the TB1 block.
Figure 2-4. CPU/System Controller Board (TB1 & TB2) Power Wiring
The ControlWave Express includes an alternative power connecter,
TB2, to provide power if none is available at TB1. For example, you
can connect a bulk DC power supply to TB2 to handle situations where
the solar panel/battery does not have sufficient power.
TB2 connections are:
TB2-1 = Power Input
TB2-2 = Ground (GND)
2.3.5 Connections to RS-232 Serial Port(s) on the CPU/System
Controller Board
An RS-232 port provides point-to-point, half-duplex and full-duplex
communications (for a maximum of 20 feet using data quality cable).
Your CPU includes two RS-232 ports and one port configurable for
either RS-232 or RS-485 operation.

Guidelines
Observe the following guidelines when constructing RS-232
communication cables:
Ensure that DCD is high to transmit (except when dialing a modem)
Verify that each RS-232 transceiver has one active receiver while
disabled (in power down mode); connect the DCD signal to the
active receiver.
Set CTS to high to transmit.
If the port is set for full-duplex operation, RTS is always ON.
Ensure that DTR is always high when port is active; DTR enables
RS-232 transceivers.
Note: Control DTR using the PORTCONTROL function block and
the _Pn_AUTO_DTR system variable in your ControlWave
project. If you turn DTR off through these mechanisms, the
port remains off, even though hardware is fully configured.
When port is set for half-duplex operation, CTS must go low after
RTS goes low.
All RS-232 comm ports support RTS, DTR, CTS, DCD, and DSR
control signals.
All RS-232 comm port I/O signals are protected by surge protectors.
2.3.6 Connections to the COM3 (RS-485/RS-232) Serial Port on the
CPU/System Controller Board
You use jumpers W12 through W16 to configure COM3 of the
ControlWave Express for either RS-232 or RS-485 operation. See
Section 2.3.2 for information on these jumpers.
Table 2-8. COM3 RS-485 Connector (TB4) on CPU/System Controller Board

Port Cables
Table 2-9 shows connector pin assignments for COM3.
Note:
If you use COM3 for RS-232 operation, pins 1 and 4 do not
apply.
Table 2-9. COM3 Connector Pin Assignment
Pin Signal Description
1 RXD+ Receive Data + input (Not applicable for
RS-232 usage)
2 RXD–/RXD Receive Data – Input
3 TXD–/TXD Transmit Data – Output
4 TXD+ Transmit Data + Output (Not applicable for
RS-232 usage)
5 Power Ground Ground
When serving as an RS-485 port, COM3 supports local network
communications to multiple nodes up to 4000 feet away.
Since the RS-485 port is intended for network communications, refer to
Table 2-10 for the appropriate connections for wiring the master, first
slave, and nth slave.
Essentially, the master and the first slave transmit and receive data on
opposite lines; all slaves (from the first to the nth) are paralleled (daisy-
chained) across the same lines. Wire the master node to one end of the
RS-485 cable run using a 24-gauge paired conductor cable (such as a
Belden 9843).
Revised Mar-2011 Installation 2-19
Note: ControlWave Express supports only half-duplex RS-485
To ensure that the “Receive Data” lines are in a proper state during
inactive transmission periods, you must maintain certain bias voltage
levels at the master and most distant slave units (end nodes). These end
nodes also require the insertion of 100Ω terminating resistors to
properly balance the network.
You must also configure switches at each node to establish proper
network performance. Accomplish this by configuring switches listed so
that the 100Ω termination resistors and biasing networks are installed at
the end nodes and are removed at all other nodes on the network. You
enable receiver biasing and termination (as well as 2-wire or 4-wire
selection) using an 8-position DIP switch located on the CPU/System
Controller board. See Table 2-3 for more information.
2.3.7 Connections to the Ethernet Port on the CPU/System
Controller Board
Caution
The RJ45 Ethernet port is connector (J1) located on the CPU/System
Controller board. The board also has one RJ45 port (J2) for the optional
Display/Keypad. Never
or damage will result.
connect Ethernet to J2 (the Display/Keypad port)
The 33MHz ControlWave Express can support one Ethernet port. This
port uses a 10/100Base-T RJ-45 modular connector (J1) that provides a
shielded twisted pair interface to an Ethernet hub.
A typical Ethernet hub provides eight 10/100Base-T RJ-45 ports (with
port 8 having the capability to link either to another hub or to an
Ethernet communications port). Both ends of the Ethernet twisted pair
cable are equipped with modular RJ-45 connectors.

These cables have a one-to-one wiring configuration as shown in
Figure 2-11. Table 2-11 provides the assignment and definitions of the
8-pin 10/100Base-T connectors.

Revised Mar-2011 Installation 2-21
Table 2-11. Ethernet 10/100Base-T CPU Module Pin Assignments
You can connect two nodes in a point-to-point configuration without
using a hub. However, you must configure the cable so that the TX+/Data pins connect to the RX+/- Data pins (swapped) at the opposite
ends of the cable (see Figure 2-12).
Figure 2-12. Point-to-Point 10/100Base T Ethernet Cable
The maximum length of one segment (CPU to hub) is 100 meters (328
feet). The use of Category 5 shielded cable is recommended.
2.4 Optional Display/Keypads
The ControlWave Express supports two optional display/keypads and a
display without a keypad:
A 2-button keypad (shown in the left of Figure 2-13)
A 25-button keypad (shown in the right Figure 2-13)
Display only (no keypad) – (see Figure 2-14)
Figure 2-13. Optional 2-Button and 25-Button Keypads
Both keypads use the same 4-line by 20-character LCD displays.
The Display without a keypad has a 2-line display with 10 characters on
the first line, and 6 characters on the second line. This display shows
variable values on line 1, and variable names on line 2.
You connect the Display/Keypad or Display to the ControlWave
Express using a cable, one end of which has an RJ-45 jack (connected
into the RJ-45 equipped with two plugs. This cable connects between
the RJ-45 display jack (J2) on the CPU/System Controller board and
RJ-45 jack (J1) on the remote Display or remote Display/Keypad
assembly. A potentiometer, provided on the keypad, allows you to set
the contrast of the LCD display.
Note: For further information on the installation and use of the
optional keypads, refer to the ControlWave Display/Keypad Manual(D5135).
ControlWave Express may include an optional Process I/O board.
The Process I/O board mounts to the CPU/System Controller board
using six nylon mounting posts.
To configure the Process I/O board, you need to set some switches and
jumpers. See Figure 3-1 for the location of the switches and jumpers.
3.2.1 Setting Jumpers on the Process I/O Board
The Process I/O board has several jumpers.
JP1: AO output source (1-5V or 4-20mA):
o 1-to-2 Installed = 4-20mA analog output
o 2-to-3 Installed = 1-5V analog output
JP3: AO power source:
o 1-to-2 Installed = system power
o 2-to-3 Installed = external power (+11 to +30 Vdc)
JP4: AI field power configuration:
o 1-to-2 Installed = external 24Vdc power
o 2-to-3 Installed = bulk input supply (system power)
JP5: AI1 input type (1-5V or 4-20mA)
o 1-to-2 Installed = 4-20mA analog input
o 2-to-3 Installed = 1-5V analog input
JP6: AI2 input type (1-5V or 4-20mA)
o 1-to-2 Installed = 4-20mA analog input
o 2-to-3 Installed = 1-5V analog input
JP7: AI3 input type (1-5V or 4-20mA)
o 1-to-2 Installed = 4-20mA analog input
o 2-to-3 Installed = 1-5V analog input
3.2.2 Setting DIP Switches on the Process I/O Board
The Process I/O board includes a single switch bank (SW1) to configure
the frequency for the high speed counters (HSC), the source current for
discrete inputs/counters, and the analog output.

Power down the ControlWave Express before you perform I/O wiring.
Shut down any processes the ControlWave Express may be managing
(or switch them over manually or handle with another controller).
Perform any hardware configuration (wiring, jumper configuration, and
installation) only when the ControlWave Express is powered down.
Before any I/O connections can become operational, you must use
ControlWave Designer to configure and then download the application
(project).
To ensure safe use of this product, please review and follow the
instructions in the following supplemental documentation:
Supplement Guide - ControlWave Site Considerations for
Equipment Installation, Grounding, and Wiring (S1400CW)
ESDS Manual – Care and Handling of PC Boards and ESD
Sensitive Components (S14006)
The ControlWave Express uses card edge terminal blocks to
accommodate field wiring. You route the wires into the
enclosure/chassis through a slot in the removable card edge cover.
ControlWave Express I/O uses compression-type terminals that
accommodate up to #16 AWG wire. Insert the wire’s bared end (approx.
¼” max) into the clamp beneath the screw and secure the wire. To
prevent shorts, ensure that no bare wire is exposed. If using standard
wire, tin the bare end with solder to prevent flattening and improve
conductivity. Allow some slack in the wires when making terminal
connections. Slack makes the wires more manageable and helps
minimize mechanical strain on the terminal blocks.
Shielding and
Grounding
Use twisted-pair, shielded and insulated cable for I/O signal wiring to
minimize signal errors caused by electromagnetic interference (EMI),
radio frequency interference (RFI), and transients. When using
shielded cable, ground all shields at only one point in the appropriate
system. This prevents circulating ground current loops that can cause
signal errors.
3.3.1 Non-Isolated Discrete Inputs (DI) on TB2 and TB3 of Process
I/O Board
Process I/O Board terminal block connector TB2 provides interface to
four dedicated non-isolated Discrete Inputs DIs – DI1 through DI4. In
addition, terminal block connector TB3 provides two additional points
that can serve as either discrete inputs or discrete outputs (DI5 and DI6
when wired as inputs).

Supply, see document PIP-ControlWave-LS.
Notes:
You must connect cable shields associated with AI wiring to the
ControlWave Express chassis ground.
Multiple shield terminations require you to supply a copper ground
bus. You must connect the ground bus to the ControlWave Express
chassis ground using up to a #4 AWG wire size. The ground bus
must accommodate a connection to a known good Earth ground (in
lieu of a direct connection from the ControlWave Express chassis
ground) and to all AI cable shields.
Use an appropriate terminal lug for shield wires and secure them to
the copper bus using industry rugged hardware (screw/bolt, lock
washer and nuts).
To use data from these AIs you must include a CWM_EIO board in
your ControlWave project using ControlWave Designer’s I/O
Configurator, and then configure it. See the ControlWave Designer Programmer's Handbook (D5125) for more information. That same

schemes and cable lengths determine the type of communication port
you need to use. In general RS-232 communications require that you
place the 3808 transmitter within 25 feet of the ControlWave Express
(local communications). You can use RS-485 communications to reach
transmitters up to 4000 feet away (remote communications).

WARNING
EXPLOSION HAZARD
Substitution of components may impair suitability for use in Class I,
Division 2 environments.
When the ControlWave Express is situated in a hazardous location,
turn off power before servicing or replacing the unit and before
installing or removing I/O wiring.
Do not disconnect equipment unless the power is switched off or the
area is known to be non-hazardous.
4.1 Powering Up/Powering Down the ControlWave Express
The ControlWave Express receives power either from a solar panel and
user-supplied battery or from an external bulk power supply attached
using connector TB1 on the CPU/System Controller board. It can also
receive power through alternate connector TB2 on the same board.
Chapter 2 includes instructions for wiring power to the ControlWave
Express. See Figure 2-3 for the location of these connectors.
Power Up
To apply power to the ControlWave Express, plug in connectors TB1
and optionally TB2 on the CPU/System Controller board. If your
ControlWave project resides in flash memory, the project will load into
SRAM and begin execution. Depending upon the setting of the SRAM
control switch, retain variable values may load as well.
Caution
Revised Mar-2011 Operation 4-1
When you disconnect power from the ControlWave Express, your
running control strategy is erased from SRAM, as is any process data
not stored in retention mode. When configured for retention and the
backup battery remains good, SRAM stores the last states of all I/O
points, audit/archive data not residing in FLASH, the values of all
variables marked RETAIN, the values of variables stored in the static
memory area, and any pending unreported alarm messages.
To remove power from the ControlWave Express, unplug connectors
TB1 and TB2 from the CPU/System Controller board.
4.2 Communicating with the ControlWave Express
You communicate to the ControlWave Express by connecting a cable
between a port on your PC workstation and one of the ControlWave
Express ports.
The port at the PC workstation must match the configuration of the
ControlWave Express port.
4.2.1 Default Comm Port Settings
As delivered from the factory, ControlWave Express communication
ports have default settings. Table 4-1 details these defaults.
Table 4-1. Default Comm Port Settings (by PCB)
Port PCB Default Configuration
COM1 CPU RS-232; 115.2 Kbps using BSAP or ControlWave Designer
protocol.
COM2 CPU RS-232; 9600 baud, 8 bits, no parity, 1 stop bit, BSAP or
ControlWave Designer protocol
COM3 CPU RS-485; 9600 baud, 8 bits, no parity, 1 stop bit, BSAP or
ControlWave Designer protocol. Intended for use with Bristol 3808 transmitters. You use jumpers W12 through W16 to configure COM3 for either RS-232 or RS-485
Note: You can re-enable the factory comm settings at any time by
setting switch 3 on the CPU module’s SW3 to “OFF.”
Ethernet
Using an optional Ethernet port (located on the CPU module), you can
connect either directly or through a network to a PC equipped with an
Ethernet port. The default IP address and mask for the Ethernet port is:
ETH1 IP Address: 10.0.1.1 IP Mask: 255.255.255.
4.2.2 Collecting Data from the ControlWave Express
OpenBSI utilities such as DataView, Data Array Save/Restore and
Harvester allow you to collect real time data (values of variables, array
values, alarm messages) and historical data (audit records, archive files)
from the ControlWave. See the OpenBSI Utilities Manual (D5081) for
details. SCADA software such as OpenEnterprise can then present this
data to an operator in the form of graphical displays and reports.
4.3 Creating and Downloading an Application (ControlWave Project)
Your ControlWave Express executes an application called a
ControlWave project. You create the project using PC-based
ControlWave Designer software. Instructions for creating a
ControlWave project are beyond the scope of this manual. Please refer
to the following sources for information:
Getting Started with ControlWave Designer (D5085)
ControlWave Designer Programmer’s Handbook (D5125)
ControlWave Designer online help
You must connect the Express to a PC running ControlWave Designer
software and OpenBSI software.
Note: You can download an application either from ControlWave
Designer or from the OpenBSI 1131 Downloader.
1. Connect a serial cable between your PC and COM2 of the
ControlWave Express.
2. Define the ControlWave project in ControlWave Designer, and
set communication and configuration parameters.
3. Download the project according to instructions in the
Downloading section of the ControlWave Designer
Programmer's Manual (D5125).
4.4 Creating and Maintaining Backups
You should always maintain a current backup of each ControlWave
project and keep it in a safe place, preferably in a location physically
separate from the controller.
The reason we recommend you keep backup files is that if a disaster
occurs that damages or destroys your ControlWave hardware (flood,
lightning strike, etc.) you don’t want to also lose its control strategy
software programs. Otherwise, when the unit is repaired or replaced,
you’d have to create a new ControlWave project from scratch, which
might take a lot longer than replacing a few damaged modules.
Caution
Always maintain a backup copy of your ControlWave project in a safe
place.
Anytime you modify your ControlWave project, be sure to create a new
backup of the new project.
You may find it useful to maintain more than one backup copy in
case the backup media itself fails, for example, a CD-ROM becomes
unreadable because it melted in the sun or a thumb drive fails
because someone spilled coffee on it.
If you don’t keep more than one backup copy, it’s a good idea to
periodically test your backup copy to verify that the media has not
failed.
4.4.1 Creating a Zipped Project File (*.ZWT) For Backup
Note: The .zwt file is a complete backup of your entire project
including code, comments and graphics. It may be stored on your
PC or removable storage media. It may also be downloaded and
archived to ControlWave Flash memory where it may be
uploaded at a later time for editing.
With your current ControlWave project open in ControlWave Designer,
perform the following steps:
1. Click File > Save Project As / Zip Project As.
Figure 4-1. Saving a Backup of Your Project
2. In the “Save/Zip project as” dialog box, specify a project name in

should also select this option to include
compiled code for libraries in your zip file.
Otherwise, you need to re-compile your
user libraries with the project when you
unzip the zwt.
This includes firmware libraries, such as
ACCOL3.FWL in your zwt.
This includes pagelayout information for printing your project, as well as graphical elements used in certain 1131 languages.
5. Click Zip and a progress bar displays the percent complete of the
zipping process.
6. When the zip process completes, you’ll see a message box reporting
successful completion. Click OK.
7. Copy the resulting zwt file to backup media (CD-ROM, thumb
drive, etc.) If you ever need to restore the project, just open the zwt
file in ControlWave Designer, load libraries as needed, then compile
the project and download it into the ControlWave.
You must establish communications with the ControlWave Express
using NetView, LocalView, or TechView before you can run the Flash
Configuration utility.
Note: For detailed information on using the Flash Configuration utility,
see Chapter 5 of the OpenBSI Utilities Manual (D5081).
1. Start the Flash Configuration utility. To do this in NetView or
LocalView, right-click on the icon for this ControlWave and
choose RTU > RTU Configuration Parameters.
To do this in TechView, click Operations > Access Flash
Parameters or click the Access Flash icon
.
2. Depending upon how your system is configured, the Flash
Configuration – Loading Options dialog box may open. If it
does, choose Load from device and wait for the utility to
retrieve all parameters from the ControlWave Express, then skip
to step 4, otherwise, just proceed to step 3.
3. Click and wait for the utility to retrieve all
parameters from the ControlWave.
4. Click and specify a name for your FCP file,
then click Save. When the status line indicates successful
completion, your FCP file in done.
5. Copy the resulting FCP file to backup media (CD-ROM, thumb
drive, etc.) If you ever need to restore the FCP parameters to the
controller, establish communications with the unit, start the
Flash Configuration utility, and load the FCP file using the Read from FCP button, then choose the Write to RTU button.
4.4.3 Backing up Data
You can back up certain types of data and restore it if needed. There are
other types of data that you can only collect, but you cannot restore.
If you have certain variables that represent tuning parameters
(setpoints, for example) you can use tools such as the OpenBSI
DataView recipe feature to save those values to a recipe file on the
PC, and then restore them at a later time. See Chapter 8 of the
OpenBSI Utilities Manual (D5081).
You can store the contents of read/write data arrays using the
OpenBSI Data Array Save/Restore utility. See Chapter 13 of the OpenBSI Utilities Manual (D5081).
You can collect alarms, and historical data (audit records, archive
files) but you cannot restore alarms or historical data.
Harmful electrical potentials may still exist at the field wiring terminals
even though the ControlWave Express power source may be turned off
or disconnected. Do not attempt to unplug termination connectors or
perform any wiring operations until you verify that all associated power
supply sources are turned off and/or disconnected.
Always turn off any external supply sources for externally powered I.O
circuits before you change any modules.
5.1 Upgrading Firmware
The ControlWave Express ships from the factory with system firmware
already installed. If you need to upgrade the system firmware (stored in
Flash memory) to acquire new functionality or restore firmware, you
can use one of several methods.
System
Firmware
Downloader
Use this tool to download system firmware to an unattended remote
ControlWave Express. To use this utility, you must set CPU/System
Controller board switch SW2-6 ON (the factory default position).
Note: For further information and detailed use instructions, refer to
Appendix J of the OpenBSI Utilities Manual (D5081).
LocalView
HyperTerminal
One of the standard OpenBSI utilities, LocalView requires OpenBSI
version 5.1 (or newer). If you have an older version of OpenBSI, use
HyperTerminal.
Note: For further information and detailed use instructions, refer to the
Flash Mode section of Chapter 5 of the OpenBSI Utilities Manual (D5081).
HyperTerminal is a communications utility program included with
Microsoft® Windows® XP.
Notes:
If you are using a version of OpenBSI older than 5.1, or do not have
OpenBSI software, you can only perform a firmware upgrade using
HyperTerminal.
While HyperTerminal is included in Microsoft® Window® XP,
some newer versions of Window® do not include it.
The screens shown here may appear different depending upon the
3. If using HyperTerminal for the first time, set the communication
properties (for the PC port) via the Properties Menu as follows:
Bits per second: = 115200, Data bits: = 8, Parity: = None, Stop
bits: = 1, and Flow control: = None and then click OK.
4. Set CPU/System Controller board switch SW1-3 ON (ON =
Force Recovery).
5. Apply power; to the ControlWave Express. The resident BIOS
initializes and tests the hardware, this process is referred to as
POST (Power On Self Test). Unless there is a problem, status
LEDS show status code 10 (LED #5 ON). If you see a different
status code, see Section 5.3.1.
6. From the HyperTerminal Mode menu (Figure 5-1), press the F
key to enter FLASH download. A message warns that the
FLASH is about to be erased; press the Y key at the prompt. The
screen displays dots as the system erases the flash memory; this
could take a few minutes.

7. When the FLASH is ready for download, HyperTerminal
repeatedly displays the letter C on the screen. In the
HyperTerminal menu bar click Transfer > Send File (see
Figure 5-2).
This section provides information on accessing ControlWave Express
components for testing, as well as removal/replacement procedures.
Field repairs to the ControlWave Express are strictly limited to the
Caution
replacement of complete boards. Replacing board components
constitutes tampering and violates the product warranty. Return
defective boards or housings to the factory for authorized service.
5.2.1 Accessing Modules for Testing
Only technically qualified personnel should test and/or replace
ControlWave Express components. Read completely the disassembly
and test procedures described in this manual before starting. Any
damage to the ControlWave Express resulting from improper handling
or incorrect service procedures is not covered under the product
warranty agreement. If you cannot properly perform these procedures,
obtain authorization and then return the device to the factory for
evaluation and repairs.
5.2.2 Removing/Replacing the CPU/System Controller Board and
the Process I/O Board
Revised Mar-2011 Service & Troubleshooting 5-5
Use this procedure to remove or replace the CPU/System Controller
board and the Process I/O board.
1. If the ControlWave Express is running, place any critical control
2. Shut down the ControlWave Express by disconnecting the
power at the CPU/System Controller assembly terminal TB1
(and if applicable, TB2).
3. Loosen the two thumb screws and remove the removable card
edge cover. Also loosen the captive fastener that secures the
CPU/System Controller and Process I/O board assembly in the
housing. See Figure 2-1 to locate these components.
4. Disconnect all removable card edge connectors from the
CPU/System Controller board and the Process I/O board. Label
or otherwise identify them so you can easily re-connect them
later.
5. If present, disconnect the display/keypad from connector J2 on
the CPU/System Controller board.
6. Carefully slide the board assembly out of the mounting
chassis/enclosure.
7. If you need to replace either the CPU/System Controller board
or Process I/O board, you need to separate the two boards. Use a
pair of needle-nosed pliers to squeeze the pair of tabs associated
with each of the six nylon mounting posts, while gently pulling
the CPU/System Controller board away from the Process I/O
board. Carefully unplug the boards from their interface
connectors. Align the replacement boards with each other and
press them together so that the interface connectors and
mounting posts properly mate; then squeeze together so that the
mounting post tabs capture the CPU/System Controller board.
8. To install the replacement boards, power must be off. Align the
boards (assembly) with the mounting chassis/enclosure so that
the Process I/O board is adjacent to the bottom of the unit and
then slide the assembly into the unit.
9. Replace all cables removed in steps 2 through 5.
10. Replace the removable card edge cover and tighten the two
thumb screws. Apply power and test the unit.
5.2.3 Removing/Replacing the Backup Battery
Note: The CPU/System Controller board draws power from the battery
only if the board loses power. The system SRAM has a standby
current draw of 20 μA maximum for each part plus 2 μA for the
real time clock. For a ControlWave Express containing 2MB of
SRAM, a worst-case current draw of 42 μA allows a battery life
of approximately 9,000 hours. This means you should not need
to replace a battery until the ControlWave Express has been in
service for an extended period (normally many years).
The CPU/System Controller board accommodates a 3 V, 300 mA
lithium coin cell backup battery housed in a coin-cell socket (S1). A
supervisory circuit on the CPU switches to battery power when the
regulated 3.3 Vdc falls out of specification. The battery then provides
backup power for the real-time clock (RTC) and the system SRAM on
the CPU/System Controller board.
Note: If the real-time clock loses its battery backup, the ControlWave
system variable _QUEST_DATE turns ON. You can monitor
this to generate an alarm. See the System Variables section of the ControlWave Designer Programmer's Handbook (D5125) for
more information.
Caution
Removing /
Replacing the
Battery
You lose SRAM contents when you remove the backup battery.
If you replace a backup battery, wait at least one minute before repowering the system. This enables the SRAM to completely discharge.
After you install the new battery, ensure that you have placed jumper
W3 on pins 1-2 (to enable the battery).
1. If the ControlWave Express is running, place any critical control
processes under manual control.
2. Remove power from the ControlWave Express.
3. Remove the CPU/System Controller board assembly from the
housing.
4. To remove the lithium battery, gently pry up the tab holding the
battery in the coin cell socket and remove the battery with a pair of
tweezers or needle-nosed pliers. Install the replacement battery.
5. Replace the CPU/System Controller board assembly in the housing.
6. Re-connect power to the ControlWave Express.
7. Once the battery has been replaced, the unit executes its Flash-
based application (“boot project”) at power-up, but all of the
current process data is lost. At power-up, the ControlWave Express
acts as though it had just been booted and reverts back to the initial
values specified in its application.
5.2.4 Enabling / Disabling the Backup Battery
Enabling
Revised Mar-2011 Service & Troubleshooting 5-7
For maximum shelf life, the CPU/System Controller board ships
from the factory with the installed lithium backup battery disabled.
You must enable it when you install the CPU/System Controller
board.
To enable the battery, install jumper W3 on pins 1-2.

The ControlWave Express cannot execute your control strategy while it
runs diagnostic routines; place any critical processes controlled by the
ControlWave Express under manual control before starting this
procedure.
WINDIAG is a software-based diagnostic tool you use to test the
performance of I/O, CPU memory, communication ports, and other
system components. .
WINDIAG is a PC-based program, so the ControlWave Express must
be attached to and communicating with a PC running WINDIAG.
Establish communication between the ControlWave Express
(with/without an application loaded) and the PC with a local or network
port under the following conditions:
Set CPU module switches SW2-3 to OFF and SW2-8 to OFF.
Turning these switches off sets all serial ports on the ControlWave
Express to 9600 baud in preparation for diagnostic testing and
prevents the boot project from running and also places the
ControlWave Express in diagnostic mode.
Connect any ControlWave Express serial communication port to the
PC provided their port speeds match. Use a null modem cable to
connect RS-232 ports between the ControlWave Express and the
PC; use an RS-485 cable to connect the RS-485 port of the
ControlWave Express and the PC. See Chapter 2 for information on
cables.
Reserve the port running a diagnostic test for exclusive use; you
cannot use that port for any other purpose during testing.
Follow these steps:
1. Start OpenBSI communications using NetView, TechView, or
require the use of a loop-back plug.
Discrete I/O Checks DIs and DOs on the Process I/O board.
Ethernet Checks the Ethernet port.
Keypad & Display Checks the optional display/keypad hardware.
Port Loop-back
Test
WINDIAG allows you to select the communication port to test.
Depending on the type of network (RS-232 or RS-485) and the port in
question, a special loop-back plug is required:
Port 1 - RS-232 uses a 9-pin female D-type loop-back plug (see
Note: You can configure RS-485 loopback by setting CPU/System
Controller board switches SW3-1 & SW3-2 ON.
Port 3 - RS-485 use loop-back wires or CPU Switch SW3 (see
Figure 5-11).
These tests verify the correct operation of the communication ports.
Note: You cannot test a communications port while you are using it.
You can only test currently unused ports. After you complete
testing on all other communication ports (and verify their correct
functioning), you must reconnect (using a now validated port)
and test the remaining untested port.
Test Procedure
Use this procedure to test the communication ports.
1. Connect an external loop-back plug to the port on the CPU you
want to test. Valid ports are:
2. Select Communications on the WINDIAG Main Diagnostics
Menu. The Communications Diagnostic screen opens:
Revised Mar-2011 Service & Troubleshooting 5-15
Figure 5-12. Communications Diagnostic Menu
3. Enter 5 in the Number of Passes field.
4. Select a port to test (click to display all available ports).
Note: The port you select must correlate to the port on which you
placed the loop-back plug in step 1.
5. Select 115200 or ALL ASYNC as the baud rate (click to
display all available rates).
6. Click RUN to start the test. At the completion of the test (which
generally takes about 5 seconds), any failed results appear in the
Status field to the right of the RUN button:
TXD RXD Failure
CTS RTS Failure
7. Click Return to Menu to display the WINDIAG Main Menu.
5.5 Core Updump
In some cases—such as when a ControlWave Express fails for no
apparent reason—you can upload a copy of the contents of SRAM and
SDRAM to a PC for support personnel and service engineers to
evaluate. This upload is called a “core updump.”
A core updump may be required if the ControlWave Express
spontaneously enters a watchdog state that affects all system operation.
This occurs when the system crashes as a result of a CPU timeout
(resulting from improper software operation, a firmware glitch, and so
on). In some cases, the watchdog state can recur but you cannot
logically reproduce the conditions.
The CPU’s RAM contains “crash blocks,” a firmware function provided
specifically for watchdog troubleshooting. You can view and save the
crash blocks by viewing the Crash Block Statistic Web Page (see the
Web_BSI Manual, D5087). On request, you can forward crash block
files to our technical support personnel. If they need additional
information to evaluate the condition, the technical support group may
request a core updump. Once the core updump process generates a file,
you can forward that file to the support personnel for evaluation and
resolution.
Use the following steps to preserve the “failed state” condition at a
system crash and perform a core updump:
1. Set switch SW2-1 on the CPU/System Controller board to OFF
(Disable Watchdog Timer). If switch SW2-4 is ON, set it to
OFF (Enable Core Updump).
2. Wait for the error condition (typically 3F on the status LEDs or
3. Connect the ControlWave Express’s Comm Port 1 to a PC using
5-16 Service & Troubleshooting Revised Mar-2011
Note: The factory default setting for switch SW2-4 is OFF.
4. Set the ControlWave Express for Recovery Mode by setting
both SW1-1 and SW1-2 to the right for open operation or both
to the left for closed operation.
5. Start the PC’s HyperTerminal program (at 115.2 kbaud) and
generate a receive using the 1KX-Modem protocol. Save the
resulting core updump in a file so you can forward it later to the
technical support group.
By setting the CPU/System Controller board switches SW2-1 and SW2-
4 both off before the ControlWave Express fails you prevent the
Express from automatically recovering from the failure and enable it to
wait for you to take a core updump.
Once you complete the core updump, set the CPU/System Controller
board’s switch SW2-1 to ON (Watchdog Enabled) and SW2-4 to OFF
(Core Updump Enabled).
Additionally, set switch SW1-1 to OFF and SW1-2 to ON.
With these switches set, power up the ControlWave Express and begin
standard operations.
5.6 Calibration Checks
The AO and AI on the Process I/O board are self-calibrating.
To calibrate the RTD, use TechView software. See the TechView User’s Guide (D5131) for more information.

Special Appendix for ControlWave Express Instruction Manual (CI-ControlWave Express)
Appendix A – ControlWave Express– Special Instructions
for Class I, Division 2 Hazardous Locations
1. The ControlWave Express RTU is listed by Underwriters
Laboratories (UL) as nonincendive (when installed in a NEMA 1 or
better enclosure) and is suitable for use in Class I, Division 2,
Groups A, B, C and D hazardous locations or non-hazardous
locations only. Read this document carefully before installing a
nonincendive ControlWave Express RTU. Refer to CI-ControlWave Express for general information. In the event of a conflict between
the ControlWave Express Customer Instruction Manual (CI-ControlWave Express) and this document, always follow the
instructions in this document.
2. The ControlWave Express RTU includes both nonincendive and
unrated field circuits. Unless a circuit is specifically identified in
this document as nonincendive, the circuit is unrated. Unrated
circuits must be wired using Div. 2 wiring methods as specified in
Article 501-4(b) of the National Electrical Code (NEC), NFPA 70
for installations in the United States, or as specified in Section 18-152 of the Canadian Electrical Code for installation in Canada.
3. The power system (solar panel and battery) are not supplied by
Emerson Process Management Remote Automation Solutions
division and are therefore unrated (see paragraph 2). Connection to
the solar panel is approved as a nonincendive circuit so that Division
2 wiring methods are not required. The nominal panel voltage must
match the nominal battery voltage (6V or 12V).
4. An optional RTD may be supplied with the ControlWave Express.
Connection to the RTD is approved as a nonincendive circuit, so the
Division 2 wiring methods are not required.
5. Signal connectors available for customer wiring are listed in Table
A-1. Network communications port and I/O wiring connections are
unrated and must be wired using Division 2 wiring methods. No
temporary connections may be made to the local port (COM1 –J4 or
J11 on CPU/System Controller board) unless the user ensures that
the area is known to be nonhazardous. Field service connections to
this port are typically temporary, and must be short in duration to
ensure that flammable concentrations do not accumulate while it is
in use.
