Sending SMS from WinCC OA

[chandra]

Hello Everyone

If I want to send SMS at a time to two phone numbers how to add one more number here.

Code: Select all

main()
{
  string number, message, sErrorText, SMSDP;
  int error;
  number  = "436767890026";
  message = "This is a test, sending SMS messages";
  sendSMS(number, message, error, sErrorText, SMSDP = "_SMS_1");
 
  if (error == 0) // If the return value equals 0, the reading was
                  // executed successfully.
  {
    DebugN("The SMS message: "+message+"; was sent successfully to the number: "+number);
  }
  else
  {
     DebugN(error, sErrorText);
  }
}

To send a SMS to multiple recipients you will have to send the message multiple times (unless you some forwarding services, which delivers the message to your distribution list).

This 'sendSMS' function uses AT commands to send the message. There is no AT command to send a SMS to multiple recipients.

Hi,I tried with same script but getting v24 error and [-2]["Timeout: No response from SMS driver!"].do we need to any configuration from sms option inside com?can you tell in generalize way how to do that so that I can send sms via wincc oa?

Just a comment. You need a special modem connected to the OA server. These modems are not supported by all Wireless vendors in the USA (only AT&t?)

it is much easier to use an internet provider and send the SMS via a REST API. For this you can use netPost()/netGet().

Hi,
Can you please explain implementation steps in general using netPost()/netGet() how sms can be sent to a particular number?do we need any kind of license for that?

Hi,

Example with Orange. You of course need account at the selected provider.

This is similar with WinCC OA . NetPost on the sent resource, netget on the receive resource.
