ii Silver Series Installation & Operation Manual

Introduction - Welcome
Welcome to the Maple Systems’ Silver Series of Operator Interface Terminals (OITs). Using graphic OITs has never been
easier. This powerful family of graphics operator interface terminals connects to programmable logic controllers (PLCs) to
provide the human-machine interface in industrial applications. The Silver Series has several features not found in other
graphic OITs. This manual explains the operation of the Silver Series OITs and how to implement the many available
features using the EZware-500 Configuration Software.

OIT Basics
Operator Interface Terminals (OITs) provide much more versatility than traditional mechanical control panels. An OIT
allows a plant floor operator to monitor current conditions of a control system and, if necessary, to initiate a change in the
operation of the system. OITs connect to programmable logic controllers (PLCs) typically through the PLC’s serial
communications port. The OIT can be programmed to monitor and/or change current values stored in the data memory of the
PLC.
OITs can have either text-based or graphics-based displays. A text-based OIT can display printable text characters but no
graphics. Some text-based OITs can display text characters in various sizes. A graphics-based OIT can display printable text
1010-1001a, Rev 02
2Silver Series Installation & Operation Manual

characters of varying fonts and sizes and graphics shapes such as icons, bitmaps, or pictures. Using pictures instead of words
or characters often greatly simplifies the operation of the OIT, making the OIT much more intuitive to use.
Some OITs use touch screen displays while others use a membrane-style keypad. Membrane-style keyboards are best used in
applications in which the keypad is likely to become dirty. Touch screen displays are placed over the OIT screen thus
providing much more flexibility than typical membrane-style keypads. Because of this, switches can be created on a touch
screen that appear only when needed.
The Maple Systems Silver Series OITs are graphics-based touch screen OITs. Before we get any further into the operation of
these OITs, it is necessary to define some terms that will be used throughout this manual.
Projects
The OIT has two basic segments of internal memory. The code memory contains the information required by the OIT that
controls how it operates such as the features supported and how it communicates to a PLC. The OIT programmer does not
have the ability to change code memory. The project memory pertains to all of the window screens created and any other
features that the OIT programmer can create using the EZware-500 configuration software. Therefore, the term project is
used to designate the file that is sent to the OIT from the EZware-500 software.
Objects
An object is any action that the OIT performs while it is communicating to the PLC. In order to get the operator interface
terminal to ‘do anything’, you must program the OIT with objects. Objects perform actions such as display text or graphics,
write a value to a PLC register, or display an alarm. Objects most often are graphics shapes that are to be displayed on the
OIT screen. For example, a Text Object is used to display text on the OIT. But objects are also used to configure the OIT to
perform some action. For example, a PLC Control Object tells the OIT to continuously monitor a PLC register that is used
by the PLC to request a new window. Some objects can display a graphics shape on the OIT screen and perform some
action. For example, a Toggle Switch Object creates a graphic object on the OIT that when pressed, activates a bit in the
PLC.
Graphics Object
A graphics object is any text, icon, or picture that can be displayed on the OIT. Graphics objects are further defined by how
they are composed or created. A Text Object is a graphics object that displays text on the OIT screen. A Bitmap Object is a
graphics object that displays a bitmap on the OIT screen. Bitmaps are files stored in the OIT to display pictures. A Shape
Object is a graphics object that displays a shape on the OIT screen. Shapes are also files stored in the OIT to display
pictures. Shapes differ from bitmaps in that shapes are stored using a vector-based file format whereas bitmaps use a
pixel-based file format. Each format has its advantages and disadvantages. We will not go into any more detail about bitmap
objects and shape objects until later in this manual. For now, think of them as objects used to display pictures on the OIT
screen. Finally, a Group Object is the most complex type of graphics object. It is a combination of other objects. Briefly, a
group object consists of one or more objects that are ‘grouped’ together and stored as one object. A good example is a
keypad, which is really a combination of several keys each designed to perform a specific task. When grouped together, a
keypad can be stored as a group object for use in other projects or windows.
Windows
A window is a screen that can be displayed on the OIT. Windows can be full-sized to completely cover the OIT display or
partially sized. Any partially sized window is usually referred to as a popup window. Windows can appear on the OIT
display by a request from the PLC or by a press from the touch screen. Windows can be configured to any size. Once a
window is displayed, it can be moved around the OIT display, removed from the display, or minimized to an icon. Windows
can even overlap each other. Each window can display graphics objects and there is no limit to the number of graphics
objects that can be placed on each window. The Silver Series is capable of storing up to 1999 windows , but the actual limit
is determined by the total amount of memory used for the application. A more in-depth discussion of windows is covered in
later chapters. For now, think of windows as screens that can be displayed on the OIT.
1010-1001a, Rev 02
Introduction 3

What is a Silver Series OIT?
The Silver Series of OITs by Maple Systems are graphics operator interfaces designed to connect to PLCs in an industrial
environment. The displays are covered with a 4-wire analog resistive touch screen designed for harsh industrial
environments. The touch screen uses the latest in touch screen technology enabling the OIT programmer to create switches
that are very fine in resolution. Unlike many other touch screen OITs on the market, the Silver Series is not limited to a fixed
number of cells in which switches can be created. The OIT programmer can create as many switches of varying sizes and
shapes as he wishes, limited only by the total amount of memory available for the project.
Three LED indicators are provided on the face of the Silver Series OIT to provide instant feedback to the OIT operator of the
current operating condition of the OIT.
LED Indicator Purpose
PWR LED (yellow) indicates if power is applied to the OIT
CPU LED (green) indicates if the OIT is operating correctly
COM LED (red) indicates communications activity on PLC port
The Silver Series OIT has two serial ports, which provide a connection to a PLC using RS-232 or
RS-485 communications and an RS-232 connection to a computer for programming. The serial ports also provide the ability
to connect multiple OITs in series to a single PLC port! The two serial ports also provide the ability to use the EZware-500
configuration software in Simulation Mode enabling the OIT programmer to test his project on the PC instead of
downloading the project to the OIT.
The Silver Series is powered using +24VDC. The viewing level of the OIT display can be adjusted using a contrast switch
located on the back of the unit, or using Local Bits LB9091 and LB9092 for Contrast Up/Down. Finally, a reset switch is
provided on the back of the OIT to reinitialize the OIT if an operational failure occurs. The Silver Series is designed for
industrial environments and carries a NEMA 4 rating as well as CE compliance for noise immunity and emissions.
The HMI504T will operate at 12 VDC.
There are currently SEVEN models in the Silver Series.

HMI550HE
(Enhanced) 10.4” 640 x 480 256-color
TFT 400 300:1 Standard Yes
Finally, the Silver Series are powered by a 200 MHz Intel XScale processor, making it one of the fastest OITs available on
the market. Even the most complicated graphics can be displayed quickly on the OIT screen. In addition, the OIT uses a
proprietary algorithm to find the most efficient means of extracting data from the PLC. This lowers the amount of
‘bottleneck’ time due to the relatively slow communications baud rate of most PLCs. Therefore, the update rate to gather
information from the PLC is very fast.

6Silver Series Installation & Operation Manual

Chapter 1 - Installation of OITs
Before You Begin
Please read the following for proper handling of your new OIT.
Unpacking the Unit
Carefully unpack the OIT. Please read any instructions or cautions that appear on the shipping container. Check all
material in the container against the enclosed packing list. Maple Systems, Inc. will not accept responsibility for
shortages against the packing list unless notified within 30 days. The equipment and its accessories were inspected
and tested by Maple Systems before shipment; all of the equipment should be in good working order. Examine the
equipment carefully; if any shipping damage is evident, notify the carrier immediately. You are responsible for
claim negotiations with the carrier. Save the shipping container and packing material in case the equipment needs to
be stored, returned to Maple Systems, or transported for any reason.
Managing Electrostatic Discharge
It is best NOT to remove the rear enclosure of the OIT. When the rear part of the enclosure is removed, the circuitry
inside is exposed to possible damage by electrostatic discharge during handling. Minimize the possibility of
electrostatic discharge by:
·Discharging personal static by grounding yourself prior to handling the OIT
·Handling the OIT at a static-free grounded workstation
·Connecting the frame ground ( ) connector of the OIT to a clean earth ground
·Placing the OIT in an anti-static bag during transport
CE Compliance
The Silver Series OITs have been tested to conform to European CE requirements per Council Directive
89/336/EEC. The European Union created these requirements to ensure conformity among products traded in those
countries. Specifically, the Silver Series OITs meet or exceed the noise emissions and immunity requirements as set
forth in the EN50081 (Emissions) and EN50082 (Immunity) standards. These products are designed to withstand
electrical noise in harsh industrial environments. They also conform to requirements that limit electrical emissions.
However, this does not guarantee that the products will be totally immune from possible malfunction in cases where
severe electrical noise occurs. Therefore, we strongly recommend that you follow the guidelines outlined in this
chapter for proper wire routing and grounding to insure the proper operation of the Silver Series OIT.
NEMA Rating
The Silver Series OITs are rated for NEMA 4/12 (indoor) or IP65 installations. This means that when the OIT is
properly mounted to a panel or other enclosure, the front enclosure of the OIT will provide protection to the inside
of the panel from splashing water, wind blown dust, rain, or hose-directed water. The OIT must be installed
according to the instructions in this chapter to be properly sealed.
Environmental Considerations
The Silver Series is designed to operate in temperatures from 0-45° C. It is intended for indoor installations and not
designed for outdoor applications. Avoid installing the Silver Series in environments with severe mechanical
vibration or shocks. Do not install the OIT in enclosures with rapid temperature variations or high humidity. Either
will cause condensation of water inside the device and eventual damage to the OIT.
1010-1001a, Rev 02
Installation of OITs 7

Safety Precautions
Please observe the following precautions when installing the Silver Series OIT. Failure to comply with these
restrictions could result in loss of life, serious personal injury, or equipment damage.
Warning: Do not operate the OIT in areas subject to explosion due to flammable gases,
vapors, or dusts.
Warning: Do not connect the OIT to an AC power source. You will cause permanent damage
to the OIT.
Warning: Do not attempt to use a DC power supply that does not meet OIT power
requirements. You may cause malfunction or permanent damage to the OIT.
Warning: Do not power the OIT with a DC power supply used for inductive loads or for input
circuitry to the programmable logic controller. Severe voltage spikes caused by these devices may
damage the OIT.
Control Panel Design Guidelines
Pay careful attention to the placement of system components and associated cable routing. These items can
significantly enhance the performance and integrity of your control application.

Control Panel Grounding
The control panel should be connected to a good, high-integrity earth ground both for safety considerations and
shielding purposes. Maple Systems cannot overemphasize the importance of good grounding. If you fail to use
good grounding procedures during installation, sporadic malfunction of the OIT may occur:
·Connect the OIT’s chassis ground terminal to a reliable earth ground with a low-resistance path.
·Route all earth ground wires that lead from the OIT, the PLC, the power supply, and the line filter to a
central earth ground point such as a barrier strip. This will ensure that no ground current from one device
influences the operation of the other devices.
·Connect the OIT chassis ground terminal to the control panel door using a heavy-gauge short braided cable
or ground wire to minimize resistance.
·Connect the power cable’s shield wire to the OIT’s chassis ground terminal.
·Connect the control panel to earth ground using a copper grounding rod close to the OIT and control panel.
Hinged doors on control panels do not provide a long-term electrical connection to the rest of the enclosure.
Corrosion develops over time and prevents good electrical contract. For this reason, a separate wire braid should be
installed from the hinged control panel to the rest of the enclosure.
For a more in-depth overview of ground wiring techniques, refer to technical note #1027, “OIT Ground Wiring and
Electrical Noise Reduction,” which you can find on our website .
Connect OIT Chassis Ground to Control Panel
To reduce the possibility of electrical interference, connect the chassis ground terminal of the OIT to a clean earth
ground. If the control panel is metal, make sure it is properly grounded. Then connect a short heavy-gauge wire
(#18 AWG) from the chassis ground terminal of the OIT to a mounting bolt on the control panel door. The
mounting bolt must have good electrical contact to the control panel; scrape away any paint that may be covering
the panel to provide a good connection.
If the control panel is made of a non-conductive material, it is essential that you connect the chassis ground terminal
of the OIT to a clean earth ground point located close to the panel.

Power Supply Selection
The power supply used to power the OIT should provide an output of +24 VDC 5% measured at the OIT power
terminal block. A 24VDC regulated power supply dedicated to the OIT is required. Refer to the installation guide
that accopanies each OIT for input current requirements.
The power cable for the OIT should be 18AWG, 2-conductor wire with a shield drain wire and protective shield
(foil or braid). The shield drain wire must be connected to earth ground at both ends of the cable. Please refer to the
“Connect the OIT to Power” section for more information.
A power line filter installed at the AC input to the OIT power supply is highly recommended as a safeguard against
conducted RF noise, which is often present on factory power lines. The wires connecting the output of the power
line filter to the power supply should be kept as short as possible to minimize any additional noise pickup. The case
of the power line filter should be connected to a quiet earth ground. The power line filter should have a current
rating of at least 3 Amps with common mode and differential mode attenuation.
Do not use the power supply used to provide power to the OIT to power switching relays, solenoids, or other active
devices.
Cable Routing and Noise Immunity
Follow these guidelines when routing cable to the OIT:
·Always route the OIT communication cable and the power cable away from any AC voltage or rapidly
switching DC control lines.
·Never bundle the OIT cables together with 120VAC power wires or with relay wiring.
·Try to keep at least 8 inches (20 cm) of separation between the OIT cables and other power wiring. If
voltages greater than 120VAC are used in the system, greater separation is required.
·If the OIT cables must come near AC wiring, make sure they cross at 90 degrees.
·Run AC power wires in a separate grounded conduit to reduce electrical noise interference.
·Keep the cable lengths for the OIT as short as possible. Do not coil excess cable and place it next to AC
powered equipment.
·Cover any equipment used in the enclosure that operates at high frequency or high current levels with a
grounded metal shield.

Installation
It is necessary to follow all installation procedures described in this chapter for electrical noise immunity and CE
compliance.
Your Maple Systems OIT is designed to connect easily to your PLC. External rear connectors provide quick
connections for power, communications and programming wiring.
There are two serial ports on the rear of the OIT (except the HMI504T, which has one serial port). Both of these are
D-subminiature 9-pin connectors. Use the female connector for RS-232 communications to a PLC. Use the male
connector for RS-485 communication to a PLC and RS-232 communications to a PC.
Use the supplied separate 3-position terminal block to provide power to the OIT.
Connect the OIT to Power
The power cable for the OIT should be 18AWG, 2-conductor wire with a shield drain wire and protective shield
foil. You may buy cable P/N 6030-0009 by the foot from Maple Systems to make these.
Always run the DC ground wire directly back to the signal return of the power supply. Do not use the chassis
ground wire as your signal return! Maple Systems recommends using an axial ferrite coil (Maple p/n 2531-0001)
with each HMI550 OIT to further reduce the electrical interference that may be conducted on the power lines.
Thread the positive and negative wires of the power cable through the ferrite coil so that the coil is no more than two
inches from the OIT’s power input.
4To connect the OIT to power:
1. Connect the power cable to the OIT
a. Strip the power cable shield to expose 2” of the black and red wires.
b. Strip about ¼” of insulation from the black and red wires.
c. Thread the black and red wires through the ferrite core. The shield wire must be outside.
d. Connect the red wire to the DC positive (+) input of the OIT power terminal.
e. Connect the black wire to the DC negative (-) input of the OIT power terminal.
f. Connect the power cable shield wire to the OIT power terminal’s chassis ground input.
2. Route the power cable to the OIT power supply. The power cable should not be any longer
than necessary.
3. Install the power supply wires as follows (with colors shown for Maple Systems cable P/N
6030-0009):

STEPS:
1. Connect the “OIT” end of the communication cable into either the RS-232 port or the RS-485 port as
required for your application (OIT housing is marked).
2. Tighten the two cable screws at each end to ensure shield ground path.
3. Route the communication cable to the PLC. Refer to the “OIT Cable Routing” section for more
information.
4. Connect the “PLC” end of the cable to the PLC and tighten the cable screws.
5. Connect the green shield wire from the cable to earth ground ( ) on the PLC. If this wire is not
present, make the ground connection inside the PLC connector.
6. The HMI530T/550T has a printer port and can be connected to an Epson compatible printer.
Panel Preparation
A metal panel or mounting surface with a minimum thickness of 15 gauge (0.059 inch/3.3mm) if cold-rolled steel or
hardened steel, or 10 gauge (0.101 inch/2.6mm) if aluminum alloy (6061-T6 preferred) is required. Thinner panels
or surfaces may bow between the mounting clamps and not form a seal with the gasket.
The area of the panel or mounting surface where the gasket comes into contact must be flat and free of scratches,
pits, and other features that prevent the gasket from sealing properly. If the panel or mounting surface is not
uniform, thick, flat, stiff, or smooth enough, then a sealant such as silicone may be required.
WARNING: The OIT requires a stiff, flat, smooth mounting surface free of blemishes
to seal properly to NEMA 4.

Example of Wiring a Silver Series OIT to a PLC

Clean and deburr the panel cutout before the OIT is installed.
Mount the OIT to the Panel
STEPS:
1. Prepare the screw clamps by positioning the metal brackets at the midpoints of the screws. Position the
screws so that the ends don’t protrude from the plastic portions.
2. Set the OIT in the panel cutout and hold it in place until all clamps are in position.
3. Tighten the screw clamps until all are uniformly snug.
CAUTION: Do not over-tighten the screws beyond snugness, or you may damage the housing.
REINSTALLATION: Because the gasket will take a “set” to the panel, be sure to reinstall the OIT to the same
panel cutout when a NEMA 4 seal is required. For best results, also replace the gasket itself.
Configuration Wiring
The OIT must be configured for a particular protocol before use. The EZware-500 software (used on a PC with
Windows 95 or higher) is used for configuring the OIT. For detailed instructions on installing and using the
software, please refer to the software documentation section of this manual.

Connect the OIT to the PC for Configuration
To configure the OIT using Maple System’s configuration software, you will need the OIT Configuration Y-adapter
Cable, Maple P/N 7431-0098. Connect the end marked “OIT” into Port 2 on the OIT, marked “PLC[RS-485]/
PC[RS-232], and connect the end marked PC into the proper COM port on your PC. The end marked “PLC” is not
used here. See the figure below for serial port pin assignments and the next two figures for connecting the Silver
series to a PC.
Many PCs no longer support RS232 serial ports. If our PC has a USB port, then you
can download projects using a USB to serial adapter, available at your local
electronics store.
Factory Configuration
Each OIT arrives from the factory with a demo project file that illustrates some of the most popular features of the
OIT. Please follow the directions enclosed in Chapter 2, Creating Your First Project, to configure your OIT for the
PLC that you are using.
Each OIT has a potentiometer located on the back for adjusting the level of contrast on the display. It is set for
optimum clarity at the factory but you can change the setting if necessary.
The OIT also has a black reset pushbutton and a four position DIP switch located through an access hole on the back
of the enclosure. The reset switch can be used to reinitialize the OIT if the OIT malfunctions. Only Dip switch 1
and 2 have functionality. Dip switch 1 puts the OIT into Touch Calibration mode. Dip switch 2 forces the OIT into
download mode, and needs to be set for downloading from a Compact Flash card. For normal operation, all of the
DIP switches should be set to the OFF position.
The touch screen of the OIT is fully calibrated before it leaves the factory so you shouldn’t need to adjust it.
However, with time the touch screen may need to be recalibrated.
4To calibrate the touch screen
1. Connect the OIT to your computer for programming.
2. From the Start menu, click Programs, then Maple Systems, then EZware-500, then the
EasyManager program.
3. Click Jump To Touch Adjust. The OIT screen should change to calibration mode.
4. After the OIT displays a crosshair cursor, you are prompted to touch the cursor for:
a. Top left position
b. Top right position
c. Bottom left position
d. Bottom right position
5. The OIT screen displays two rectangular objects. To determine whether the touch screen is
properly calibrated, place and hold your finger somewhere on the touch screen other than on
the rectangular spots. The crosshair cursor should appear directly under your finger. If
needed, press the left rectangle to repeat the calibration. Press the right rectangle to end
calibration.
6. Once you have completed calibration, press the touch screen again to return to normal
application mode.
