5.4.2 

TC_DISCON: Terminate connection via the GSM network 

Meaning 

The TC_DISCON instruction on an S7-1200 with CP 1242-7 terminates an ISO-ON-TCP, 

UDP, SMS or telecontrol connection that was established with the TC_CON instruction. 
You will find detailed information on the connection types in the description of the TC_CON 

instruction. 
TC_DISCON terminates the connection to the telecontrol server only logically. If you want 

the connection to the telecontrol server to be terminated physically, configure the connection 

as a "Temporary connection" in the "telecontrol server" parameter group in STEP 7. 
At the TCP/IP level, the connection is retained. Temporary stations terminate the connection 

automatically after sending the data. 
The ID parameter references the GPRS connection. The ID must be unique within the CPU 

and the same as the ID used with 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.
