search element in array and convert to booblean and memorize this boolean

[vicens]

Hi,

I have an array with X cells (variable).On the other hand I have a control string. I want search this control in the array. If I meet it, in the array, a LED will switch on. For example:

cicle nº 1

Array       Control

a                 b                  LED (a): off

b                                     LED (b): on

d                                     LED (c): off

                                       LED (d): off

                                       LED (e): off

cicle nº 2

If this control changes, now is "d", the LED (d) will switch on, but the LED (b) wil keep switched on.

Array       Control

a                 d                  LED (a): off

b                                     LED (b): on

d                                     LED (c): off

                                       LED (d): on

                                       LED (e): off

cicle nº 3

If this array changes, all the LEDs will switch off and will start the "memory" of the LEDs.

Array       Control

a                 a                  LED (a): on

b                                     LED (b): off

c                                     LED (c): off

e                                     LED (d): off

                                       LED (e): off

cicle nº 4

Array       Control

a                 c                  LED (a): on

b                                     LED (b): off

c                                     LED (c): on

e                                     LED (d): off

                                       LED (e): off

Thank you, and sorry for my english...

Hi Vicens,

there are search functions (search array element)...
To memorize the last state of your LEDs you should use a shift register in your loop. If the LEDs should only switch on you can use an OR-operation to include newer results.

What's the condition for switching LEDs off? Your question is not very specific on that... Should they switch off after 2 iterations of your loop (AND with FALSE in this case)?

Hi Vicens,

be more specific. Attacheded VI's might help you.

Hi, GerdW and cities

sorry for my awful explanation.

Every X time the array update (and can changes the values) only one once. This array contains 7 differents cells (a, b, c, d, e, f and g), and some cells can be empties.

During this time, I recibe, via Data Socket, messages, named string control in the vi added. So in each iteration the program can read only one message.The content of the message is any cell (a, or b, or f,...).

The objective is to show which message are in the array.

PD: I've replace DS by the string control in the vi added.

PD2 (to cities): can you convert your 'vi' to LV 7.1?

Thank you

LV 7.1 /Xp

I am sorry. But I can't, from 8.2 i can downgrade only to 7.1. Can anyone other?

There you have the vis in 7.1

Thank you! AitziberH
