5.4.4 

TC_RECV: Receive data via the GSM network 

Meaning 

The TC_RECV instruction allows the reception of data via programmed connections of the 

following types: 
●  ISO-ON-TCP connections 
●  SMS connections 

To receive SMS messages, the phone number of the sender must be configured in the 

STEP 7 configuration of the receiving CP (authorized phone numbers). The sender must 

support the CLIP function. 
The phone number of the connection partner must be entered in the "TCON_PHONE" 

SDT. 
Wake-up SMS messages are filtered out. 

●  Telecontrol connections 

 

 

Note 
Receiving SMS messages from different senders   
If you want to receive SMS messages from different senders, you have two alternatives: 
  You configure several connections (TC_CON, TC_RECV, TC_DISCON). 

or 

  You may only enter no telephone number for only one configured connection in the 

required data block "TCON_PHONE" in the "PhoneNumber" parameter. When receiving 

messages, this is then interpreted as a placeholder for all authorized connection partners.

 

You will find more detailed information on the connection types in the description of the 

TC_CON instruction. 
The ID parameter references the GPRS connection. The value of ID must correspond to the 

value used for ID by TC_CON. 
The INTERFACE parameter references the GPRS interface of the required local CP. The 

value must be the same as that used by TC_CON for INTERFACE.
