My project is based on sending information in a SQL database on an external web server.

At the customer's, cost issue, I would put only a S7-1200 connected to internet.

function TM_MAIL seems in its infancy and has many flaws apparently ...

See my other post : /tf/WW/en/Posts/87609#top

I would like the S7-1200 can do a query like: http://www.copedi.be/IMAP/LOG.php?CLIENT=1245&SONDE=5&MESURE=27,5

(http request, port 80)

And website respond only ‘OK’

You can try in "live"

With PHP code I get the info (CLIENT=1245 SONDE=5 MESURE=27,5) and I said OK, because I received the request.

If S7-1200 does not receive a response (OK for example) after a certain time, it indicates an error. free code to redo the request.

This may interest a lot of people to allow the S7-1200 to interact with a website. website can answer anything other than OK.

Thanks for your advice.

Hey,

Does still nobody hass an answer?

I am also very interested in an example program.

Hello!

Simply use TSEND_C block, for parameters: DATA: use string variable: put the following inside:

'GET /s7/index.php?test=12 HTTP/1.1$R$LHost: www.bla.com$R$LConnection: close$R$L$R$L'

For LEN parameter calculation you can use LEN function but you should add +2 to it.

That's all.

Special characters:

·  CONST

·  TRF_CR_LF:='$R$L';//CarriageRETURNundLineFeed

·  TRF_CR:='$R';//CarriageReturn

·  TRF_LF:='$L';//LineFeed

·  TRF_KOMMA:=',';//Komma

·  TRF_STX:='$02';//STX,StartText

·  TRF_ETX:='$03';//ETX,EndText

·  END_CONST

I am trying talk to a RUT500 Router and I am trying to implement your solution.

I have a connection established but nothing happens when I trigger the REQ.

I am trying to send the following HTTP request:

GET /cgi-bin/sms_send?number=00306972512782&text=test HTTP/1.1$R$LHost: 10.100.10.2$R$LConnection: close$R$L$R$L

Is that correct?

There is one problem, in the connection property we need to enter IP address of the request target.

But in the question COPEDI asks about the symbolic hostname (not IP).

What is the right solution in this case? 

I have the same problem, but i can't solve it!

HI,

did u manage to solve the problem .

I have the same situation now with RUT 500.

Hi

maybe problem after timestamp protocol length. Its two character more?

Communication packet begin of GET is 2 not correct character ?

Maybe some web server works for this character but many server answer "bad request"

Where is possible get TSEND source code, I interested to correct it.

The two characters are your max string length (254) and your actual length.

you sould not sent the first 2 bytes of your S7 string.

Hey,

I am getting response 'HTTP1.1 400 bad request' using that data format. Can you help me?
