Various running message display

Greetings!

HAs anyone encountered working with displaying an alarm indicators like machine troubles:

Low water level at cooling tower
Low pressure level at compressor
Fan / pump troubles
etc..

We wanted to display these various alarm messages into a single board display for maintenance team monitoring aside from those red lamps and buzzers they could hear.

Had someone worked with these projects before?
Can help me how this Say 7 segment board able to display those different messages?
Any controller used? PLC?

Thank you very much.

I think you need to use a HMI. There are several HMI on the market with very good prices, that will display any alarms you want.

Hi jmsmoreira

I will not used a touch panel here for the reason that our client requires a larger display (like the welcome message in an airport)..a running message.. A seven sigment display. However, I dont know yet how I could display different messages into that boeard.

I've done 2 of these at our site using D-A514 units from www.signdata.com, I use the RS232 coms from an AB SLC 5/03 sending out the ASCII code to tell the unit what to display they work very well. We have them set up to display fault messages from the lines.

Another old-fashioned simple method, with an alarm display box for each alarm.

We use FactoryTalk ME station on a cheap TV screen, using it as a computer monitor.
A-B has also led displays for this kind of visualisation.

Have a look at the Alpha displays from London Electronics -

You can store up to 80 messages in your Alpha display.
You can call your stored messages 3 ways ...
Discrete switch inputs
Binary logic inputs 24V NPN or PNP
BCD logic inputs 24V NPN or PNP
You can store your messages using one of 2 methods...

Use the InfraRed keyboard to program messages
Use a PC to program messages
If you have less than 10 messages, the remote InfraRed keyboard may be used, but you will probably find the PC method easier and faster.
