Applying Power

This section describes power connections for initial desktop setup and
programming. Refer to Chapter 6 for installation wiring instructions.

The MicroView operates on 24 VDC power supplied either through
the power port or the communications port. For run-time operations
with the MicroLogix controller, the MicroView is supplied with 24
VDC through the cable from the MicroLogix controller connected to
the communications port.

For application download/upload operations, the MicroView is
supplied with 24 VDC through the power port using a separate power
adapter. You can use the AC to DC Adapters: Catalog No. 2707-PS120
for 120 VAC or Catalog No. 2707-PS220 for 220 VAC power.

ATTENTION

!

Verify that the power is disconnected from the
power source before wiring. Failure to disconnect
power may result in electrical shock.

If you use an AC/DC power adapter, make sure
that the supply voltage to the MicroView is 11 to
25 volts DC and of the correct polarity. Incorrect
voltage may damage the MicroView.

Powerup Sequence

The powerup sequence is automatic, you do not have to respond to
the screens. During the Power Up or Reset sequence, the MicroView
performs a series of initialization and diagnostic tests.

1. When power is first applied, the display will light and remain

blank for approximately one second.

2. Then the display is tested, every pixel of the display is turned on

for one second. If all of the pixels do not turn on, the display
may be defective.

3. The display is again cleared and the MicroView verifies the

system memory checksum, program checksum and system RAM.

4. If all tests pass, the MicroView will flash the boot code power–

up screen for one second.

It is the responsibility of the application designer to document the
operation of an application program. This chapter only provides basic
guidelines. Before running an application, you should understand
what processes are being controlled and monitored.

ATTENTION

!

Bit Write Mode

1 Publication 2707-UM005B-EN-P

The application designer can assign the function keys [F1] and [F2] to
set or clear a bit at a controller address. This bit may control a variety
of processes. It is the responsibility of the application designer to
document the use of the bit write mode function keys.

The function keys of the MicroView can be
assigned different functions depending upon the
application. The application designer must
document these functions. Make sure you
understand any function key operations prior to
operating the MicroView. Failure to do so may
result in unintended operation.

5-2 Running Applications

Screen Types

Screen Navigation

Application screens can have a variety of appearances. The MicroView
can display five types of screens.

• Menu and Sub-Menu Screens

• Security Screens

• Data Display Screens

• Data Entry Screens

• Recipe Screens

The MicroView provides several options for changing the screen
displays:

• Screen Links

• Advisor option

• Function keys

Screen Links

Use the [NEXT] and [PREV] keys to step backward and forward
through this sequence.

Main Menu and Sub-Menu screens list screens that can be accessed by
pressing the assigned numeric key [1] through [8]. A typical Main
Menu screen provides links to individual screens or sub-menus:

1 Pump
2 Mixer

In the example above, pressing [2] at the Main Menu displays the
status of a holding tank. Pressing [4] displays a Sub-Menu of the recipe
options.

3 Tank
4 Recipe

Advisor Option

Applications can allow screen changes that are controlled by a logic
controller. When the logic controller writes a valid screen number to a
specified Advisor register, the corresponding screen is displayed. The
controller can initiate a screen change based upon a variety of inputs
to the controller. For example, a pressure limit switch can be used to
initiate the display of a pressure control screen. It is the responsibility
of the application designer to document when and what screen
changes may occur.

Publication 2707-UM005B-EN-P

Running Applications 5-3

Function Keys

An application designer can link function keys [F1] and [F2] to
individual screens. Pressing an assigned function key displays the
function key number for approximately 0.5 seconds and then the
assigned screen. It is the responsibility of the application designer to
document the operations assigned to function keys. There are two
function key modes:

• Auto Return

• Continue

Auto Return

Auto return function keys return to the initial display after the linked
screen is executed. For example, assume that an application is
displaying screen #6 and an auto return function key [F1] is linked to a
recipe screen #10. When [F1] is pressed, the recipe screen #10 is
displayed. After the operator downloads a new recipe on screen #10,
the initial screen #6 is displayed.

The following table describes when the return to the initial screen
occurs.

Sub-Menus

Security Screens

Sub-Menu screens function like the Main Menu. The only difference is
that you must navigate through the other screens or use assigned
function keys to access the Sub-Menus.

Security screens limit access to parts of an application. Although the
text on a security screen may be changed by the application designer,
many applications will use the default text:

“LIMITED ACCESS”

CODE:

A security code is a series of 1 through 8 digits. Each security screen
can have up to 3 code entries. Entering any one of the codes provides
access.

To enter a security code, use the numeric keypad. An asterisk (*) is
displayed for each number entered. Press [ ] after the entire code is
entered.

If a valid security code has been entered, the next linked screen is
displayed. If an invalid security code has been entered, an error
message appears. Once you acknowledge the error condition by
pressing [ ], you can re-enter the code.

Installing the MicroView Operator Interface 6-5

Connecting DC Power

During run-time operation, the MicroView is supplied with 24 VDC
power by the MicroLogix controller through the cable connected to
the Communication Port.

When the MicroView is connected to a personal computer for
application uploading/downloading a separate DC power source must
be connected to the Power Port. The MicroView accepts power
supply voltages from 11 to 25 VDC. The DC power supply must be
capable of providing at least 1.5 watts.

The following MicroView accessories meet these requirements. Use
either depending upon your source voltage.

• 120 VAC Input, use AC to DC Adapter (Catalog No. 2707-PS120)

• 220 VAC Input, use AC to DC Adapter (Catalog No. 2707-PS220)

To connect the communications cabling, between the MicroView and
MicroLogix, refer to Chapter 7.

sections:

Section Page

Wiring Guidelines 7-1
Connecting RS-232 Devices 7-2
Communicating with a MicroLogix Controller 7-3

Here are some recommendations on how to reduce noise on the
communications connections:

• Careful wire routing helps reduce or minimize electrical noise.

Route incoming power to the terminal by a separate path from
the communications cables.

• Do not run communications wiring and power wiring in the

same conduit.

• Where communications and power wiring must cross, make

their intersection perpendicular.

• Proper grounding helps to limit the effects of noise due to

Electromagnetic Interference (EMI). To avoid problems caused
by EMI, all cables must be shielded and grounded at one end.
Grounding is also an important safety measure in electrical
installations.

8-2 Troubleshooting and Maintenance

Common Operating Problems

Error Messages

If there is no display on the MicroView, verify that 24 VDC is present
at the 8-pin DIN connector (pins 1 and 2). If not, check the DC power
from the MicroLogix controller through the communications cable.

The most common problems are related to cabling configurations and
the communication parameters (baud rate, data bits, parity). These
parameters must be identical for both the MicroView and the
controller. Cabling and the communications parameters are always the
first things to check.

If the communications cabling and communications parameters are
correct, perform the diagnostic tests to rule out any non-functioning
features of the MicroView.
