Overview

The SIMATIC MV420 is a particularly compact code reading

system suitable for close-up to mid-range reading distances

(approx. 10 mm to 400 mm).

SIMATIC MV420 has been specifically designed for detecting

and evaluating a variety of machine readable codes in the pack-

aging industry (e.g. F&B, pharmaceuticals, and tobacco) and in-

dustrial production (e.g. automotive, electronics, and solar). The

list of readable codes includes all standard matrix codes and

bar codes which can be reliably detected - mostly independent

of the printing technology applied and carrier medium used.

One key feature of the unit is its ability to read data matrix codes

(DMC). The SIMATIC MV420 device family is flexible, reliable

and easy to use.

Highlights at a glance:

• Compact design with IP67 degree of protection.

• Variety of lenses with variable reading distances.

• Integrated high-performance lighting.

• Web server technology: Parameterizable with regular Web

browser.

• Interfaces: Ethernet, PROFINET, RS232, DI/DO, and direct

connection to RFID communication modules (ASM).

• Exceptionally high reading speeds, depending on the model.

Further important product characteristics are:

• Excellent read algorithms based on the SIMATIC MV440 and

VS130-2 code reading systems and many years of experience

in industrial applications.

• No special knowledge required for reliable parameterization

of reading features. Parameterization usually unnecessary,

and is only required for difficult to read codes. "Setup" is per-

formed automatically by presenting a readable code pattern.

• Code quality evaluation: displays the key quality parameters

of the code to be read.

• Customized user interface can be easily generated with

SIMATIC WinCC flexible/WinCC.

• Web-based user interface; can run on a variety of platforms

meeting the following requirements: Internet browser (IE 6.0 or

higher), JAVA-VM (MS, SUN).

• Password protected user interface with integrated access

rights administration.

• Web-based user interface available for easy integration with

an HMI device. The browser and JAVA VM requirements pre-

viously mentioned also apply in this case.

• 6 language versions (operator interface, manual and online

help are each available in German, English, French, Spanish,

Italian, and Chinese).

In addition, SIMATIC MV420 SR-P offers the following highlights:

• Autotrigger mode: Automatic detection of a code without an

external trigger signal

- Saving of sensor technology and cabling

- Reduced potential for error as there are fewer components

- Solution for applications where proximity switches and light

barriers cannot be used

• Open web API interface for comfortable creation of custom-

ized applications and PC based camera remote control

• Multicode: reads multiple codes in one step within the same

field of view.

- ID-Genius: a high-performance code reading algorithm for

poorly legible directly marked data matrix codes

(DPM: Direct Part Marking)

Application

Key features of the SIMATIC MV420:

• Code reading

• Comparing the read result with a preset value

• Formatting of read results for further use

The range of application for the SIMATIC MV420 product family

extends to practically all areas of industrial production. The pos-

sibilities for use range from identification of stationary parts to

fast moving parts on conveyor systems. The high-performance

integrated lighting allows for an extremely compact design. The

unit is protected from environmental influences with a degree of

protection IP67. The SIMATIC MV420 code readers are therefore

suitable for all industrial applications, also for direct marking

(Direct Part Marking - DPM). In addition to industrial production,

thanks to its small size and flexibility, the SIMATIC MV420 code

reader is also ideally suited to the packaging industry (e.g. F&B,

pharmaceuticals and tobacco).

The MV420 code readers include all common communication in-

terfaces, such as Ethernet or PROFINET, and can therefore be

connected to a wide variety of systems. An integrated RS422 in-

terface makes it possible to use all of the RFID communication

modules, such those required for the PROFIBUS connection. In

this case, the combination of code reader and RFID reader is

also possible on one communication module.

The reading devices are particularly easy to use and commis-

sion despite the wide variety of options for use. Parameters are

automatically configured for most applications. If reconfiguration

is required, however, parameterization can be carried out with-

out the need for pre-installed software via the integrated Web

server using an Internet browser.
