Sending Text to a Button

arunmohan

I can send any text onto a particular button by the command used in Netlinx

---

SEND_COMMAND Panel,"'^BAT-520,1,Enter City'"

Now I want to send the text in a char variable instead of the direct text, How the syntax will change?

Please helpme

You would simply put your char variable in place of "Enter City"

SEND_COMMAND Panel,"'^TXT-520,1,cVariable'"

Also:

SEND_COMMAND Panel,"'^TXT-520,0,cVariable'"

Will display the text in all states of the button... on, off, etc.

^BAT appends text to a variable text button. If you ONLY send it once (ever), it will work, otherwise use ^TXT.

Oops! I didn't even notice that!

My experience with ^TXT is that it is a comma delimited string and that in the form you have it, the text that will be sent to the button is the string 'cVariable'. Do I have this wrong? I don't have a touch panel to check it with right now.

I think what you need to do to use ^TXT with a variable argument is something like:

SEND_COMMAND Panel,"'^TXT-520,0,',cVariable"

I think to use the ^BAT form (if appropriate) you'd need something like:


SEND_COMMAND Panel,"'^BAT-520,1,',cVariable"

which is sort of funky looking because you have the two commas together -- one as part of the string and one as a delimiter.

You are correct. It's difficult to read things here on the forum without proper formatting. TXT & BAT commands are like so:

^TXT-<address> , <state> , <text>
^BAT-<address> , <state> , <text>
Where:
<address> is the variable text address of the button intended for the text
<state> is both, off or on (0, 1, 2 respectively OR states 1 - 256 for multi-state buttons)
<text> is the text meant to be on the button, whether it be a variable or static text (up to 50 chars per AMX-PI)

^BAT appends text to a button. So if you wanted your button to say "This is silly", you could do this:
send_command dvPanel1 , '^BAT-520 , 0 ,This '
send_command dvPanel1 , '^BAT-520 , 0 ,is '
send_command dvPanel1 , '^BAT-520 , 0 ,silly '
// Variable text button reads "This is silly"

^BAT is helpful when hitting that magic text length when sending to a panel (which I *thought* was 188 characters, though I've seen some people say 200 and AMX-PI say 50 . . .)

Just like Google, AMX-PI is your friend (except when it's wrong.)

See the post after the one you quoted. The command you are trying to use is slightly wrong. Look at the ' and , below.

Good.

Do you see why it works and why
"'^BAT-520,1,cVariable'"
does not give you the result you want?

There is a metric buttload of lessons about strings in this little example.

Well, maybe only a half metric buttload, but it's important to understand.

Communication between IPad and ni-3100

I have a problem to communicate between the iPad and the ni-3100. When I contact to the tpcontrol in the iPad and I press on the button it doesn't do anything (it even doesn't change color from red=press to yellow=release). In the netlinx I see that the iPad is online. I don’t know what the problem is.
