Why Marquess from EZAutomation/AVG are the #1 Market Leader in LED Message displays, visible up to 800 ft. and connecting to a PLC?

Background: Consider it to be an Intelligent Stack light. It shows you Alarm Messages, Machine and Production Status, real time. 1 Line 10 Character to 8 Line 80 Characters visible to 800 ft. Just Red or tricolor. Indoor or Outdoor with Sunlight Readable Option. It can be mounted right on top of your machine or hung from the ceiling. It is a much better solution than digital white boards as it connects easily to your PLC network and can withstand harsh environment as compared to a large computer screen. A fork lift can run into it and it will still continue to do its job. On the other hand, a digital white board if damaged in any way requires full replacement.

It is EXTREMLY cost effective.

How does it pay for itself in 3 months? It cuts down Maintenance and downtime , improves operator efficiency, provides enhanced visibility, increases safety and compliance and above all improves line productivity brought out by human competitiveness.

Many engineers specify it to read scales that can be read by truckers loading up their cargos from quarries, farms, mines and the like.

These marquees seamlessly connect to 95% of all PLCs including ControlLogix and CompactLogix.

We are the #1 Supplier of Marquees in North America because:

1. We have the widest variety: 8 sizes, over 200 models, Indoor or Outdoor, red or tri-color, NEMA 12 or 4X, sun-light readable option with an incredible brightness of 12000 NITs, shipped the same day or max 5 days.

2. Unlike others, we give you a full 5x7 dot matrix international character set as compared to their 4x5 characters.

3. It communicates to 95% of all PLCs including Ethernet IP connection to Rockwell’s ControlLogix and CompactLogix PLCs.

4. It has a patented design with 1/3rd the weight, 1/3rd the power and 1/3rd the cost as compared to Rockwell or Spectrum that limit their marquees to 35 degree C ambient, which automatically shut down when the temperature inside the marquee cabinet rises above 55 degree C. Temperature inside the cabinet can easily rise 20 degrees because normal LEDS generate a lot of heat except our LEDs. Our marquees are rated at 60 degree C ambient.

5. We used custom LEDs that are matched in luminance. All LEDs lose luminance with time, but if you start out with matched LEDs, luminance loss is uniform. EZMarquees will look the same even after 10 years of installation because of this feature.

6. Mixed character sizes on same line allows use of a smaller marquee saving cost.

7. Stores 200 messages.

8. Free ASCII string generating software to load strings in your PLCs.

9. Scrolling, blinking or stationary messages.

10. Sunlight Readable Tricolor Marquees with 12,000 NITs luminescence.




iMarquees that allow Marquees to be added to a PLC Network without need to modify PLC code AT ALL. It reads tags and the information in the tags and displays that information on the Marquee.

No need to change PLC Ladder Logic!

No ladder logic change required when adding a display to communicate Machine/Process status and alarms to plant floor as long as the data is available in PLC. The EZ Intelligent Marquee becomes another node on the PLC network which reads and writes to PLC registers just like an HMI/Operator Interface does.

Most Major PLC Protocols Built-in

  • All EZPLC protocols
  • Allen Bradley EtherNet/IP & DF1
  • Siemens ISO over TCP/IP
  • Automaton Direct (K-Sequence, Do-More, Click Series etc..)
  • Mitsubishi
  • Omron
  • DH+ optional
  • Modbus RTU & TCP/IP

Math Logic / Scripting

The Intelligent Marquees offer a sophisticated control, called the Multi-function Object. As the name implies, this Object allows you to perform multiple functions, including Mathematical and Logical operations on PLC data. For example, you can set/reset multiple bits & transfer constants or variables or expressions to tags. Remarkably, this Benefit allows a user to perform up to 20 operations with one Object. Performing these Multiple functions is a very useful feature to offload mathematical & logical computations from the ladder logic to the Marquee.

Display & Store User Programmed Messages based on Event (Tag address) and Time

iMarquee has 3 types of messages, as shown in the figure below.

  1. iMarquee allows you to program a (single) Priority Message along with a condition (such as Bit is set, a register is beyond a value or outside a range, etc). iMarquee would continuously monitor the programmed variable, and display this message when the condition is met. No other message is displayed when priority message is displayed, so this is used for only critical messages.
  2. The second types of messages are Machine/Process Status & alarm messages. Like the priority message, user needs to program message display conditions. You can program any number of such messages. If multiple messages need to be displayed, iMarquee would cycle through these messages.
  3. The normal messages are programmed along with a message number, and which of the programmed message needs be displayed is controlled by the PLC. Only for this type of message, you will have to provide logic in the PLC. The Priority and Status/Alarm messages DO NOT NEED to do anything with the PLC program, only its tag contents.

Import tag database from PLC

With EZ Intelligent Marquee Software, you can automatically import your tag database via .CSV or Excel format. Once the tags are in the software, you then assign a distinct message for each event (bits) and values (registers).

Alarm/Message database

EZ Intelligent Marquees offer a sophisticated alarm system. You can monitor events (bits) and values (registers). The values can then be monitored for a variety of conditions (=, >, <, in/out of range). The alarms can be selectively displayed, printed and / or logged in a alarm database. Practically an unlimited # of messages can be stored inside the marquee itself!
