314 Fieldbus control with embedded fieldbus
The pin configuration of the RS-232 connector is shown below.The maximum length
of the communication cable with RS-232 is restricted to 3 meters (9.8 ft).
The drive can be set to receive all of its control information through the fieldbus
interface, or the control can be distributed between the fieldbus interface and other
available sources, for example, digital and analog inputs.
