The MV500 optical readers are equipped with a Web server that provides Web Based
Management (WBM). Using the WBM, you can configure your readers. Among other things,
you can create reader-specific programs and program sequences and run diagnostics.

After you have called the IP address of your optical reader, a welcome screen opens. This
provides important information from the optical reader that can be integrated into numerous
environments, since HTML5 is not required for this page.
Advantages
● Independent of the operating system or the Web browser you are using.
● Does not require Java Runtime on the visualization device.
● Requires little memory and performance on the visualization device.
● Can be integrated easily into existing applications.
Available HTML pages
Once the connection to the reader has been successfully established, the WBM welcome
screen appears:

NOTICE
Security recommendation: Enable user management
3.1 Layout of the WBM
Using the WBM, you can configure the SIMATIC MV500 optical readers.
After starting the WBM the first time, no user management is enabled. To make sure that
no unauthorized persons can access the reader settings, we recommend that you enable
the user management, create new user profiles and delete any existing default user profiles
after starting the WBM for the first time.
For additional information on logging in to WBM and creating/deleting user profiles, refer to
the section "User management (Page 136)".
When you have created new user profiles you need to log in with one of these user profiles
when you restart the WBM.

Fast focus detection
You use this parameter to specify whether or not Fast code type detection is to
be performed for the subsequent adaptation. You define the default setting for
this parameter in the menu "Settings > Options > Extras > Operation on the
device".
On: Code type detection is automatically performed for the following code types
if decoder steps are present in the source program:
• DMC (with set decoder type)
• Available 1D codes (except pharma code)
Off: Complete code type detection for the following code types is performed for
each decoder step:
• DMC (with currently set decoder type)
• PDF417
• Available 1D codes (except pharma code)
• QR
• DMC (with decoder type "ID-Genius", if not already done in step 1 and com-
patible with other settings)
You use this parameter to specify whether or not Fast focus detection is to be
performed for the subsequent adaptation. You define the default setting for this
parameter in the menu "Settings > Options > Extras > Operation on the device".
On: With focus detection, the image display or ROI area is not subdivided into
subROIs. This means that lighting and focus are not checked and adjusted for
each individual subROI. This setting shortens this process step. Recommended
for even, flat object holders.
Off: The image display or ROI area is divided into subROIs. This means that
lighting and focus are checked and adjusted for each individual subROI. Rec-

Application
5.1 Program
Automatic adaption with the help of the "Full program" function
The "Full program" function is similar to the function of the "READ" button. Both functions
automatically adapt the reader, but differ in some points.
Requirements
● To use the function, you need a code in the target area of the reader. Use the image
display to ensure that the code is located in the target area of the reader.
Default settings
Before starting the "Full program" function, you can define some settings which are adopted
by the automatic adaptation. These settings can shorten the duration of the function or
disable unwanted options. You can specify the following settings in advance:
● Fast code type detection
● Fast focus detection
● Set the lighting (flash or continuous light / "Image acquisition > Lighting")
● Set number of codes to read ("Decoder > Multicode")
● Define decoder steps for the codes to be expected
● Define subROIs for the expected codes
Function description
When the function is started, the reader changes to "Adaption" status, automatically
optimizes the various settings and adjusts the parameters accordingly. Automatic adaption
goes through the following phases:
1. Structure analysis
In this phase, the image area defined by the exposure ROI is divided into subROIs if
needed. The exposure and focus are set individually for each subROI. Finally, the 3 best
results - subROIs with the best sharpness values - are selected and transferred to the
next phase.
2. Decoding
In this phase, a search for code is conducted in several cycles with different filters,
sharpness values and exposures based on the result from the 1st phase. Cycles with
different setting combinations are run until a code is recognized. As soon as a code is
found in one of the cycles, the result is transferred to the next phase.
3. Optimization
In this phase, the focus and exposure are optimized again for the code type adopted from
the 2nd phase and the specified settings. Finally, the various lamp settings and image
enhancement procedures (filters) are performed again with these optimized settings to
ensure that the best read quality is achieved with the filter used.
The result of the best read quality is selected as the final result for this adaptation.
If automatic adaptation is started via the "READ" button of the reader, an alignment phase is
performed before the structural analysis. In the alignment phase, you can also align the
reader without the image display.

When adaption is complete, the reader automatically switches to edit mode ("Edit").
Depending on the result of the adaptation, the following steps are performed:
● NOK
The status display shows a message with detailed information and further instructions on
the adaptation result and the possible causes for "NOK".
● OK
The reader switches to the "Result" program step and enables formation of result. The
status display shows a message with detailed information and further instructions on the
adaptation result. The changes are applied to the currently selected program. To save
these changes, you must manually save them in the desired target program.

5.1.3 "Image acquisition" program step
You start setting up the reader in this program step and make all settings that have an effect
on the image acquisition.
This includes the following settings, among others:
● Auto-setup
● Image
● Trigger
● Lighting
● E-focus
● Verification
5.1.3.1 Auto-setup
The Auto-setup functions assist you in the parameter assignment of a new or existing
program. You have the option of having the parameters assigned automatically or making
the settings manually.
In this area, you can use the three buttons to have the WBM automatically make the basic
settings and set the basic orientation of the reader.

Exposure
• Auto
• Manual
Auto Setting the exposure control:
With this setting, each processing is preceded by a series of
image acquisitions so that the reader can set the optimum
brightness.
Position the Region of Interest (ROI exposure) of the image
so that the image area to be processed is included. Exposure
control is then based on this ROI.
To enable optimal operation of the brightness control, the
object to be processed must remain inside the ROI after the
trigger until exposure control is finished. The processing time
increases accordingly, whereby the cycle time and the high
limit of the cycle time include this increase in the processing
time.
To rule out reflections, use a limited ROI in this case.
Set a high limit for the exposure time and brightness in this
setting. Depending on your application it maybe necessary to
specify a high limit for the exposure time, for example, to
prevent excessive blurring due to movement.
The "A" button is hidden.
With this setting, you specify the exposure time and brightness manually. This allows you to set the exposure according
to your own experience in conditions when the automatic
function might fail.
This setting is necessary for short image acquisition times,
for example at high reading speeds.
When you click the "A" button, you trigger a single adaption.
The reader calculates suitable values for the exposure time
and brightness. With this as a basis, you can then fine tune
the settings.
If the trigger comes during the image acquisition when automatic exposure control is active, it is ignored and an "N_OK"
is output.

This setting therefore is especially useful for applications with
high movement speeds or poor lighting conditions. The increased light sensitivity causes a greater pixel noise com-
