Operation with PLCs 
Generally, the INSYS GSM will be connected to a PLC or a PC with a pertinent application 
via the serial interface and will provide the data connection for it via GSM to the remote 
device.  
Depending on which PLC you are connecting, you must initialize the INSYS GSM or the 
modem accordingly. 
 
 
 
For setting the PLC data, two modem settings are available:  
¾
  Configure PC modem  
When you activate the entry "Configure PC modem", the modem will be config-
ured at the PC (e.g. at the control center) for the according PLC. 
¾
  Configure the GSM device at the PLC 
When you activate the entry "Configure GSM device at PLC" , the modem will be 
configured directly at the PLC.
