System Protocol no broadcasting

The selected protocol in the Controller Properties Dialog Box - System Protocol Tab Overview does not support broadcast messages. To send a broadcast message, the system protocol should be set to DF1 Master, DF1 Radio Modem, or DF1 Slave.
NOTE: Logix Designer versions 37 and later do not support controllers with serial ports. The
System Protocol
tab appears only in Logix Designer versions 36 and earlier for controllers with a serial port.
