CPU Backup Battery
CPU Memory
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).
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.
FLASH Memory
The ControlWave ExpressPAC 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 ExpressPAC 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

1.6 Software Tools
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
ExpressPAC. Figure 1-2 graphically presents the programming
environment.
The tools which make up the programming environment include:
ControlWave Designer is your load-building package. It offers
several different methods for you to create control strategy programs
that run in your ControlWave ExpressPAC. 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).
Communication
Protocols
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).
Flash Configuration Utility – Parameters such as the BSAP local
address, IP address, etc. are set using the Flash Configuration
Utility, accessible via OpenBSI LocalView, NetView, or TechView.
For information on the Flash Configuration Utility, see Chapter 5 of
the OpenBSI Utilities Manual (document D5081).
In addition to the Bristol Synchronous/Asynchronous Protocol
(BSAP), ControlWave supports communications using:
Internet Protocol (IP) - You can use an Ethernet port or use a serial
port with serial IP using Point-to-Point Protocol (PPP).
Other supported protocols include: Modbus, Allen-Bradley DF1, CIP,
DNP3, and Hex Repeater. See the ControlWave Designer online help
for details and restrictions.
This chapter discusses the physical configuration of the ControlWave
ExpressPAC, considerations for installation, and instructions for setting
switches and jumpers.

2.2 Installation Overview
ControlWave ExpressPAC ships from the factory with all components
wired and mounted, except for the unit’s solar panel and primary
battery; these items are shipped separately.
Installing a ControlWave ExpressPAC involves several general steps:
1. Installing and configuring the hardware. This includes:
a) Mounting the chassis on a panel, wall, or vertical pipe. (See
b) Enabling the backup battery by setting jumper W3 on the
CPU/System Controller board to position 1 to 2. (See Section
2.3.2)
b) Setting switches and jumpers on the CPU/System Controller
board (see Section 2.3.1 and Section 2.3.2) and on the Process
I/O board (see Section 3.2.1 and Section 3.2.2) and placing both
boards (as a single assembly) into the chassis.
d) Connecting communication cables, including a cable to a 3808
transmitter, if required. (See Sections 2.3.6, 2.3.7,2.3.8, and
3.3.8.)
e) Wiring I/O. (See Section 3.3)
f) Installing a ground wire between the enclosure ground lug and a
known good Earth ground. (See Section 2.2.2)
g) Connecting the RTD probe (if required). (See Section 3.3.7)
h) Installing the solar panel and rechargeable battery (if
applicable).(See Section 2.3.5)
i) Wiring power to the unit. (See Section 2.3.4)
j) Turning on power. (See Section 4.1)
Figure 2-2. ControlWave ExpressPAC NEMA 3R Enclosure Dimensions
Mount the unit to a panel, a wall or to a vertical 2 inch pipe clamped
at the rear of the unit using two clamps and four bolts. See Figure 2-4 and Figure 2-5. If you mount to a pipe, it must be anchored in
cement deep enough to conform to local building codes associated
with frost considerations.
If your unit requires a solar panel, you can mount it to the same 2
inch pipe that holds the controller. Make sure there is adequate
clearance for the solar panel. For more information on the solar
panel, see Section 2.3.5.
Only connect power wiring after the unit is mounted and properly
grounded.
I/O wiring, external power wiring, RTD wiring, antenna cabling,
and communication port cabling enters the bottom of the unit
through conduit or special function fittings. (See Figure 2-3.) I/O
wiring is routed through the left side of the unit (right when facing
the front) via a ¾ inch conduit fitting.
The ControlWave ExpressPAC enclosure includes a ground lug that
accommodates up to a #4 AWG wire size. Once you install the unit, run
a ground wire between the enclosure’s ground lug and 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, tin the ground wire with solder
before you insert it into the chassis ground.
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.
To configure the CPU/System Controller board, you need to set some
switches and jumpers.

either a 6Vdc, 12Vdc or 24Vdc bulk power input. You can estimate the
maximum current required for your ControlWave ExpressPAC using
the following equation:
Bulk +6/12/24 Vdc Supply Current = CPU/System Controller Board (with

Connector TB1
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 low powered versions of the ControlWave ExpressPAC
using a solar panel connected to a factory-installed rechargeable 7AH
(6V/12V) lead acid battery at connections TB1-1 and TB1-2.
Alternatively, a factory-installed lithium battery/battery pack or a usersupplied bulk power supply connects to TB1-3 and TB1-4.
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 factorysupplied internal battery). Not available on units with Ethernet.

Figure 2-7. CPU/System Controller Board (TB1 & TB2) Power Wiring
If you power the ControlWave ExpressPAC using a bulk DC power
supply use 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 ExpressPAC 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.
Terminal Block
Connector TB2
The ControlWave ExpressPAC 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.
Depending upon the type of power system you choose, your
ControlWave ExpressPAC may require a solar panel. The solar panel
charges a rechargeable 6V 7AH lead acid battery. Solar panel wires
enter the unit through a liquid tight conduit fitting on the bottom of the
enclosure and connect to TB1 on the CPU/System Controller board.
If your ControlWave ExpressPAC is configured to use a solar panel to
Caution
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.
You can mount the solar panel to a 2” to 2-3/8” pipe using muffler
(pipe) clamps. You secure the pipe clamps using four ¼-20 nuts and
washers. (See Figure 2-8 and Figure 2-9.)
You must swivel the solar panel for optimum alignment with the sun. In
the northern hemisphere, face the panel due south (not magnetic south).
In the southern hemisphere, face the panel due north (not magnetic
north).
1 and 5 watt solar panel systems have adjustable tilt angles. Adjust the
tilt angle for maximum performance to accommodate the latitude of
your installation site. Table 2-5 shows the angle (from horizontal) at
which you should install the solar panel to maximize annual energy
output. At most latitudes, performance can be improved by less of an
angle during the summer and more of an angle during winter.

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.

(see Figure 2-11) to connect with other devices (such as a PC, a printer,
another ControlWave [except the CW_10/30/35]) when the
ControlWave ExpressPAC uses the full-duplex PPP protocol.

Guidelines
Revised Mar-2011 Installation 2-25
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.
2.3.7 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 ExpressPAC for either RS-232 or RS-485 operation. See
Section 2.3.2 for information on these jumpers.
Table 2-9. COM3 RS-485 Connector (TB4) on CPU/System Controller Board

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 2-11 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 (daisychained) 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).
Note: ControlWave ExpressPAC supports only half-duplex RS-485
networks.

TXD– RXD– RXD–
RXD+ TXD+ TXD+
RXD– TXD– TXD–
GND GND GND
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).
To establish proper network performance, you enable receiver biasing
and termination (as well as 2-wire or 4-wire selection) using an 8position DIP switch located on the CPU/System Controller board – see
Table 2-3. The biasing and termination is required at the end nodes and
is not used for other nodes of the network.
2.3.8 Connections to the Ethernet Port on the CPU/System
Controller Board

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

connect Ethernet to J2 (the Display/Keypad port)
The 33MHz ControlWave ExpressPAC 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 2-17. Table 2-12 provides the assignment and definitions of the
8-pin 10/100Base-T connectors.
Figure 2-17. Standard 10/100Base-T Ethernet Cable (CPU Module to Hub)
Table 2-12. 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 2-18).
Figure 2-18. 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 Radios and Modems
ControlWave ExpressPAC supports several different third-party
radios/modems. You can:
order ControlWave ExpressPAC with the radio/modem factory
order the unit without a radio/modem and then order the supported

bracket)
radio/modem from Emerson separately, and install it yourself. This
option is called “radio-ready.” If you choose to install it yourself,
you must ensure that the remote antenna (associated with a casemounted radio) is properly installed and connected.
2.5 Optional Display/Keypads
The ControlWave ExpressPAC supports two optional display/keypads
and a display without a keypad:
A 2-button keypad (shown in the left of Figure 2-19)
A 25-button keypad (shown in the right Figure 2-19)
Figure 2-19. Optional 2-Button and 25-Button Keypads
Figure 2-20. Display with No Keypad
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
ExpressPAC 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.
ControlWave ExpressPAC may include an optional Process I/O board.
The Process I/O board stands vertically on edge against the inner left
side of the enclosure and 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 ExpressPAC before you perform I/O
wiring. Shut down any processes the ControlWave ExpressPAC 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
ExpressPAC 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 ExpressPAC uses card edge terminal blocks to
accommodate field wiring. You route the wires into the
enclosure/chassis through the left side of the unit (right when facing the
front) via a ¾ inch conduit fitting.
Shielding and
Grounding
ControlWave ExpressPAC 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.
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 internally-sourced, 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

Notes:
You must connect cable shields associated with AI wiring to the
ControlWave ExpressPAC chassis ground.
Multiple shield terminations require you to supply a copper ground
bus. You must connect the ground bus to the ControlWave
ExpressPAC 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
ExpressPAC 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

and Pulse2) with a 1 second scan rate. Pulse counters act like high speed
counters but cannot function with contact relays because they lack
contact debounce circuitry.

To use data from these pulse counter/discrete inputs you must include
a CWM_ECPU 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 manual includes an I/O Mapping section that
describes, for advanced users, the I/O map for this board. To read a DI
value, look at the appropriate offset for the _STATE variable for the
board.

3.3.7 Resistance Temperature Device (RTD) Inputs on CPU/System
Controller Board
CPU/System Controller board connector TB6 provides connection to a
3-wire 100 ohm platinum bulb RTD (using the DIN 43760 curve). The
RTD connection enters the unit through the bottom of the enclosure.
Wire the RTD according to Table 3-9 and Figure 3-4 and Figure 3-5. In
this configuration, the return lead connects to the RTD- terminal and the
two junction leads (Sense and Excitation) connect to the RTD+ and
RTD EXC terminals.
Never ground the RTD cable shield at both ends or allow it to come in
Caution
Table 3-9. RTD Connections to CPU/System Controller Board Connector TB6
contact with metallic/conductive conduit because multiple ground paths
can cause RTD input errors.
To install the RTD probe, screw the fitting body into the thermowell
with a 7/8” open-end wrench. While you apply pressure against the
sheath to force the tip of the RTD probe into the bottom of the
thermowell (so that the probe tip is in contact with the bottom of the
thermowell), tighten the 9/16” nut using an open-end wrench against
the 7/8” fitting body.
To use data from the RTD you must include a CWM_ECPU 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
manual includes an I/O Mapping section that describes, for advanced
users, the I/O map for this board.

3.3.8 Connections to a Bristol Model 3808 Transmitter
You can connect a Bristol 3808 transmitter (digital) to the ControlWave
ExpressPAC through either an RS-232 or RS-485 port. Communication
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
ExpressPAC (local communications). You can use RS-485
communications to reach transmitters up to 4000 feet away (remote
communications).
Figure 3-6 details RS-232 wiring connections required between the

WARNING
EXPLOSION HAZARD
Substitution of components may impair suitability for use in Class I,
Division 2 environments.
When the ControlWave ExpressPAC 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 ExpressPAC
The ControlWave ExpressPAC receives power either from a solar panel
and factory-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 ExpressPAC. See Figure 2-3 for the location of these
connectors.
Power Up
To apply power to the ControlWave ExpressPAC, 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 ExpressPAC, 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 ExpressPAC, unplug
connectors TB1 and TB2 from the CPU/System Controller board.
4.2 Communicating with the ControlWave ExpressPAC
You communicate to the ControlWave ExpressPAC by connecting a
cable between a port on your PC workstation and one of the
ControlWave ExpressPAC ports.
The port at the PC workstation must match the configuration of the
ControlWave ExpressPAC port.
4.2.1 Default Comm Port Settings
As delivered from the factory, ControlWave ExpressPAC
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 ExpressPAC
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 ExpressPAC 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 ExpressPAC 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 ExpressPAC.
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
the File name field. In Figure 4-1 we chose the name mynewproj.
3. In the Save as type field, choose Zipped Project Files (*.zwt).
4. In the Zip Options area, select which additional files you want to
include in the zwt file. Other than increasing the file size of the zwt,
it doesn’t hurt to check any or all of these options.
Zip Frontend-Code If you selected Zip User-Libraries you
Zip FW-Libraries
Zip Pagelayouts
If you created your own user-defined
functions or function blocks, you must
select this to preserve them.
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 ExpressPAC
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 ExpressPAC, 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.
You need the following equipment to perform the procedures described
in this chapter:
To run diagnostics software:
PC with WINDIAG software, and either OpenBSI LocalView,
NetView, or TechView for communications
Null modem interface cable
Loop-back plug (See Figure 5-7 and Figure 5-8.)
To perform firmware upgrades:
Null modem interface cable
PC with the following software:
o OpenBSI LocalView
o OpenBSI System Firmware Downloader and either NetView,
LocalView, or TechView for communications.
o HyperTerminal (included in Windows®)
To replace the SRAM backup battery:
Tweezers or needle-nose pliers
Note: When you service a ControlWave ExpressPAC on site, we
recommend that you close down (or place under manual control)
any associated processes. This precaution prevents any processes
from accidentally running out of control when you conduct tests.
Service and repairs should only be performed by qualified
personnel. Any damage to the unit resulting from improper
handling or incorrect service is not covered under the product
warranty agreement. If qualified personnel are not available, the
unit should be returned to the factory (with prior authorization)
for evaluation and repairs.
Caution
Harmful electrical potentials may still exist at the field wiring terminals
even though the ControlWave ExpressPAC 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 ExpressPAC 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 ExpressPAC. 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
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
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,
This section provides information on accessing ControlWave
ExpressPAC components for testing, as well as removal/replacement
procedures.
Field repairs to the ControlWave ExpressPAC 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 ExpressPAC components. Read completely the
disassembly and test procedures described in this manual before
starting. Any damage to the ControlWave ExpressPAC 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
Use this procedure to remove or replace the CPU/System Controller
board and the Process I/O board.
1. If the ControlWave ExpressPAC is running, place any critical
3. Shut down the ControlWave ExpressPAC by disconnecting the
power at the CPU/System Controller assembly terminal TB1
(and if applicable, TB2).
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. Loosen the upper and lower locking tabs and rotate them so the
boards can be removed together.
7. Carefully slide the boards toward the front of the unit and
unplug the MVT cable from the CPU/System Controller board
connector P1.
8. 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.
9. 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.
10. To install the replacement boards, power must be off. Align the
Process I/O board with the upper and lower guides so that the
CPU/System Controller board is on the right side. Slide the
boards (assembly) into the unit, making sure to re-connect the
MVT cable to connector P1 on the on the CPU/System
Controller board before you fully insert the assembly.
11. Rotate the upper and lower locking tabs to secure the boards.
12. Replace all cables removed in steps 2 through 5.
13. Apply power and test the unit.
5.2.3 Removing/Replacing the Primary Battery System
Note: This procedure refers to the factory-supplied battery system
(lithium battery/battery pack or lead acid battery) that provides
primary power to the ControlWave ExpressPAC. For information
on replacing the SRAM backup battery, see Section 5.2.4.
Use this procedure to remove or replace the CPU/System Controller
board and the Process I/O board.
1. If the ControlWave ExpressPAC is running, place any critical
control processes under manual control.
2. Open the enclosure cover.
3. Shut down the ControlWave ExpressPAC by disconnecting the
power at the CPU/System Controller assembly terminal TB1
(and if applicable, TB2).
4. Carefully remove the battery wires from CPU/System Controller
board connector TB1 (unplugged in step 3) making sure they
don’t contact each other.
5. Loosen the four screws that secure the battery cover/radio
mounting plate to the one piece mounting bracket.
6. Slide the battery cover/radio mounting plate toward the top of
the unit so that its slots clear the mounting screws and remove it.
If a radio or modem is present, carefully set the battery
cover/radio mounting plate to one side. Note: Lithium battery
systems are located on the inside of the battery cover/radio
mounting plate.
7. Carefully remove the primary battery system (with cables
attached).
8. To install the new battery system, reverse the steps you did in
steps 3 through 7, but perform the reversed steps in reverse
order. After you connect power, test the unit.
5.2.4 Removing/Replacing the Backup Battery
Note: The CPU/System Controller board draws power from the backup
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 ExpressPAC
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
ExpressPAC 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).
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 ExpressPAC is running, place any critical
control processes under manual control.
2. Remove power from the ControlWave ExpressPAC.
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 ExpressPAC.
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
ExpressPAC acts as though it had just been booted and reverts back
to the initial values specified in its application.
5.2.5 Enabling / Disabling the Backup Battery
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.
Enabling

6. Loosen the four screws that secure the battery cover/radio
mounting plate to the one piece mounting bracket.
7. Slide the battery cover/radio mounting plate toward the top of
the unit and remove it with the radio or modem installed.
8. Remove the mounting screws from the inner side of the battery
cover/radio mounting plate and remove the radio/modem..
9. To install the new radio/modem, reverse the steps you did in
steps 3 through 8, but perform the reversed steps in reverse
order. After you connect power, test the unit.
5.3 General Troubleshooting Procedures
This section presents some procedures to troubleshoot problems with
the ExpressPAC.
5.3.1 Checking LEDs
The ControlWave ExpressPAC includes two light emitting diodes
(LEDs) on the CPU/System Controller board. These are a watchdog
LED (WD – CR1 right) and an idle LED (IDLE – CR1 left).
When the watchdog LED is ON (RED) it indicates a program crash;
when OFF it indicates normal operation.
When the idle LED is ON (RED) it indicates the CPU has free time at
the end of its execution cycle. This should be on frequently. When the
idle LED is OFF, it indicates the CPU is overloaded.
The Ethernet port connector (J1) on the CPU/System Controller board
contains two LEDs that indicate transmit (yellow) and receive (green)
activity when lit.
5.3.2 Status Messages on LCD Display
If your unit includes the optional LCD display, you may see the
following status codes.
Table 5-1. LCD Status Codes

5.3.3 WINDIAG Diagnostic Utility
System initialization in progress
Caution
The ControlWave ExpressPAC cannot execute your control strategy
while it runs diagnostic routines; place any critical processes
controlled by the ControlWave ExpressPAC 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 ExpressPAC
must be attached to and communicating with a PC running WINDIAG.
Establish communication between the ControlWave ExpressPAC
(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
ExpressPAC to 9600 baud in preparation for diagnostic testing and
prevents the boot project from running and also places the
ControlWave ExpressPAC in diagnostic mode.
Connect any ControlWave ExpressPAC serial communication port
to the PC provided their port speeds match. Use a null modem cable
to connect RS-232 ports between the ControlWave ExpressPAC and
the PC; use an RS-485 cable to connect the RS-485 port of the
ControlWave ExpressPAC 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.
Controller board.
Prom/Ram Checks the SRAM and FLASH memory.
Analog Input Checks AIs on the Process I/O board.
Communications Checks serial communication ports COM1,
COM2, and COM3. The External loop-back tests
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
Port 2 - RS-232 use loop-back wires (see Figure 5-7).
Port 3 - RS-232 use loop-back wires (see Figure 5-8).
Figure 5-8. COM3 RS-232 & RS-485 Loop-back Wires
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 5-8).
These tests verify the correct operation of the communication ports.
Test Procedure
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.
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
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.
In some cases—such as when a ControlWave ExpressPAC 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 ExpressPAC
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).
Note: The factory default setting for switch SW2-4 is OFF.
2. Wait for the error condition (typically “NOTRUN” on the
optional display).
3. Connect the ControlWave ExpressPAC’s Comm Port 1 to a PC
using a half duplex null modem cable.
4. Set the ControlWave ExpressPAC 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 ExpressPAC fails you prevent the
ExpressPAC 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 ExpressPAC and
begin standard operations.
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 ExpressPAC Instruction Manual (CI-ControlWave EPAC)
Appendix A – ControlWave ExpressPAC– Special
Instructions for Class I, Division 2
Hazardous Locations
1. The ControlWave ExpressPAC RTU is listed by Underwriters
Laboratories (UL) as nonincendive and is suitable for use in Class I,
Division 2, Groups C and D hazardous locations or non-hazardous
locations only. Read this document carefully before installing a
nonincendive ControlWave ExpressPAC RTU. Refer to instruction
manual CI-ControlWave EPAC for general information. In the event
of a conflict between CI-ControlWave EPAC and this appendix,
always follow the instructions in this appendix.
2. The ControlWave ExpressPAC 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 local communications port terminates in a circular 5-pin
connector on the bottom of the ControlWave ExpressPAC RTU’s
instrument front cover. The wiring on this connector is unrated. No
connections may be made to this port unless the user ensures that the
area is known to be nonhazardous. Connections to this port are
temporary, and must be short in duration to ensure that flammable
concentrations do not accumulate while it is in use.
4. The optional power system (solar panel and battery) approved for
use with the nonincendive ControlWave ExpressPAC RTU are
described in the model specification. The 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).
5. An RTD is normally supplied with the ControlWave ExpressPAC.
Connection to the RTD is approved as a nonincendive circuit, so
that Division 2 wiring methods are not required.
6. Signal connectors available for customer wiring are listed in Table
A-1. Network communication port and I/O wiring connections are
unrated and must be wired using Division 2 wiring methods.
7. The UL listed nonincendive ControlWave ExpressPAC RTU may
include radio/modem communications (listed on model spec.) that is
used in conjunction with a 5W, 12V, 7AH lead acid battery system.
Connection to the radio or modem is approved as a nonincendive
circuit, so that Division 2 wiring methods are not required.
