Fieldbus control 285
 Control interface
In general, the basic control interface between the fieldbus system and the drive
consists of:
Note: The words “output” and “input” are used as seen from the fieldbus controller
point of view. For example an output describes data flow from the fieldbus controller
to the drive and appears as an input from the drive point of view.
Planning
Network planning should address the following questions:
• What types and quantities of devices must be connected to the network?
• What control information must be sent down to the drives?
• What feedback information must be sent from the drives to the controlling
system?
