About PWS3000/3100
D.1 Introduction
The PWS3000/PWS3100 is equipped with a 9.4" VGA sized
(640Hx480V) flat panel display and analog resistive touch
screen. The IP 65 (NEMA 4) rated front panel seal and
INDUSTRIAL GRADE touch screen make the product rugged and
durable. There are THREE display options: color TFT LCD,
black and white FSTN LCD, and blue mode STN LCD. You can
choose appropriate ones according to your application's
requirement. Every PWS3100 Workstation comes with a LPT port
that allows you to hardcopy the current screen. This is a
way of generating documents with sophisticated formats. The
upgraded model PWS3100 is more compact and compatible with
PWS3000 as well.
This chapter describes how to install your Workstation in a
panel, set its DIP switches, and make cables for its
communications and printer ports.

The Workstation passes the tests of IEC 68-2-6 and
IEC 68-2-27.
Your unit is rated for NEMA 4 (water-tight) and
NEMA 12 (dust-tight) environment, provided you
install it with its gasket intact in a similarlyrated enclosure.
D.3 Dimensions of PWS30xx
This section illustrates the dimensions of the Workstations
themselves as well as the cutout dimensions. The unit of
dimensions is millimeter. You should allow 10 cm (4") of
clearance behind the workstation for cable connectors and 5
cm (2") above and below for airflow. Method of installation:
Mount the PWS to the preserved hole from the front side.
Attach the mounting brackets from behind, and fasten the
screw of the brackets with a screwdriver. Don't tighten the
screws with too much force or it may cause a damage of the
panel.

original thickness.
D.4 Power Connections
You must ground your Workstation at all times. You should
also ensure that the Workstation is on the same ground as
any other equipment connected to its communications ports.
D.4.1 Power Connector
The three-position power connector accepts 24VDC only. The
unit's power consumption is shown in the following:

Be sure to use all three terminals when connecting power. To
make a connection, strip about 0.64 cm (1/4") of insulation,
turn the screw counter-clockwise until the gap is wide open,
insert the wire all the way in, and turn the screw clockwise
until it's tight.
D.4.2 Electrical Grounding
You must make sure that your Workstation is properly
connected to earth ground, to prevent it from radiating
radio frequency noise.
If you connect a communications cable to your unit after
static electricity has built up or when the Workstation and
the other device are on different grounds, the resulting
discharge could damage the electronics in either device.
D.5 Touch Panel
The PWS30xx/PWS31xx is equipped with a 9.4" VGA sized
(640Hx480V) flat panel display and analog resistive touch
screen.
You can design touch keys for each of your screens. You can
configure a touch key to display another screen or control
an on/off location within your PLC. The shape of the touch
key must be rectangular, but the size of a touch key is
configurable and can be as small as a single touch switch or
as large as the entire screen. One screen can have up to
80x60 touch keys for PWS3100. For each changeable Object of
a screen, the Compile function of ADP3 automatically groups
D-5
PLC Workstation
Supplement D
those touch switches that the display area of the Object
covers to form a touch key for the selection purpose.
When you press a touch key, the Workstation responds by
sounding the buzzer for 200 milli-seconds (default) and
reversing the color of that touch key for 200 milli-seconds.
With the feedback, you know the Workstation accepts your
key-press. You can use Miscellaneous Settings dialog box of
ADP3 to set the parameter of touch screen for your
Workstation.

D.5.1 Built-in Touch Keypads
The built-in touch keys are touch keys that the ADP3
automatically configure for your application so that you
don't have to spend any time to program them. The built-in
touch keys allow the operator to select and change a PLC
location very easily.
There are two groups of built-in touch keys called Numeric
Touch Keypad and Password Reentering Keypad that the
Workstation displays for you to change data. The Numeric

D.7 Self Test
After power is applied, the Workstation runs a self-test
that checks its hardware. After each test, the Workstation
displays the result as shown in the following example. The
version number of ROM BIOS refers to the EPROM chips, which
will likely never change. If your Workstation doesnot have
battery or doesnot process data that should be keeped by
battery such as recipes and nonvoltile logged data, you can
choose not to test the battery by disable "Battery check” in
the Configuration Table.

If you have never configured your Workstation, the self-test
may report a failure of the real time clock. If this happens,
configure as described in section D.10. If you have never
downloaded an application to the Workstation, the self-test
may report a problem in the flash chips. You can ignore
these errors. If you have interrupted a download to the
Workstation by switching off the power, disconnect the
communication cable, or click cancel button in the ADP3
while a download is in progress, the self-test may report a
problem in the Firmware Checksum or Application Checksum.
You can ignore these errors and try to download again.
If there are any items of the self-test the Workstation
doesn't pass, the message "System error is detected! Press
screen to continue.” appears. The Workstations continues its
operation after you press screen.
We will not describe the operations of PWS3000 specifically,
because of the similarity between the PWS3000 and PWS3100.

D.12 Entering Password
After the self-test, if the DIP switch No.6 is on, the
Workstation displays a keypad to prompt you to enter a
password. If DIP switch No.6 is off, the Workstation doesn't
ask you to enter a password and the default user level is 1
after the power-on self-test if the DIP switch SW8 is set to
on; the default user level is 3 if the SW8 is set to off.
If a password is required, the Workstation doesn't continue
its operation until a legal password is entered.
D.12.1 Password and User Level
The Workstation saves passwords in the Real Time Clock chip.
A password must have eight numeric characters. When you
create a password, you must specify the user level
associative with that password. The user level of a password
determines the privilege of the user who enters that
password to start the operation of the Workstation. When a
user wants to use the function of the System Menu, change to
another screen, or make change to a PLC location, the
Workstation checks the user's user level. There are three
user levels: level 1, level 2, and level 3. Level 1 users
have the highest privilege and Level 3 users have the lowest
privilege.
The passwords and their user levels of your application are
unpredictable until you define them.
D.12.2 Registering Passwords
To register new passwords or modify existing passwords for
your application, you have to create an Action button on a
screen and assign the function "Display Password Table" to
that button. When the Workstation is running the application,
a level 1 user can get the password table as the example
shown below when he presses and releases an Action button
that displays the Password Table.
You can register up to eight passwords for your application.
To change a password or the user level of a password,
