Does TeleService (TS Adapter) support SMS transmission via an analog or ISDN modem in the landline network?

  • Entry
  • Associated product(s)

TeleService (TS Adapter) does not support the transmission of an SMS via a fixed network modem (analog, ISDN). The TS Adapter does not understand or support any provider-specific protocols like UCP (Universal Computer Protocol) or TAP (Telelocator Alphanumeric Protocol).

Sending an SMS message by means of TS Adapter I or II
The TS Adapter I (as from V5.2) and TS Adapter II support transmission of SMSs via a GSM wireless modem installed on the serial RS232 interface.

The TeleService delivery package includes function block FB48 "SMS_SEND", which is put into the STEP 7 library when you install the TeleService S7 Library. If a plant is to send an SMS, the plant's user program has to call the function block FB 48 "SMS_SEND".

The function block FB48 "SMS_SEND" can only be used through the MPI interface of an S7 CPU.

Sending an e-mail by means of TS Adapter IE (Basic)
The TS Adapter IE (Basic) the e-mail transmission function. Call function block FB49 "AS_MAIL" in the user program of an S7 CPU in your plant in order to send an e-mail by means of the TS Adapter IE (Basic). The FB49 "AS_MAIL" transmits an e-mail from the CPU to a mail server using SMTP (Simple Mail Transfer Protocol).
If the provider proposes the "SMS by e-mail" function, you can send an SMS indirectly through an e-mail. This function sends an e-mail with fixed format (telephone number of the recipients, message text, etc.) to the mail server. The server recognizes that the e-mail contains an SMS message and forwards it to the mobile telephone recipient over the wireless network.

Function blocks FB48 "SMS_SEND" and FB49 "AS_MAIL"
The function blocks FB48 "SMS_SEND" and FB49 "AS_MAIL" are included in the TeleService delivery package and are put into the STEP 7 library when you install TeleService.
