Answer Posted / manickam.kc
DF1 protocol is an Allen-Bradley data-link layer protocol
that combines .... Softlogix 5800 provides virtual PLC
control using a PC and RSLogix 5000. ...
The DF-1 protocol is an asynchronous byte-oriented protocol
that is used to communicate with most Allen-Bradley RS-232
interface modules. More specifically, the DF-1 serial frame
composition is that of a conventional RS-232 serial frame,
where DF-1 forces some of the serial parameters such as 8
data bits, no parity, and a maximum baud rate of 19200.
Further, the DF-1 protocol specifies how to send data
through a conventional RS-232 serial port, in order to
communicate with the corresponding Allen-Bradley products.
