5 MODEM  MD720 in OPC Mode 

5 

GPRS modem 

In the OPC Mode the MODEM  MD720 is configured by program building blocks of 
the connected S7-200 PLC. The MODEM  MD720 establishes autonomous the 
radio data connection via GPRS between the connected S7-200 device and the 
OPC server SINAUT MICRO SC. 

SMS-Adapter 

In addition also in OPC Mode the connected S7-200 device can send messages by 
SMS: 

●  directly to other subscribers of the SMS service, or  

●  through gateways to fax machines. 

To send a SMS, the GPRS connection to the OPC server SINAUT MICRO SC will 
be interrupted. 

GSM-Modem 

Also the MODEM  MD720 in OPC Mode can answer service data calls from analog 
modems, ISDN modems or GSM modems. 

 
 

Notice 

You can find details about these functions in the system manual of the OPC server 
SINAUT MICRO SC.
