Control interface
In general, the basic control interface between the fieldbus system and the drive
consists of:
Protocol
Modbus
N2
FLN
BACnet
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 bypass.
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 to the system (drive only or system)?
• What feedback information must be sent from the bypass system to the
controlling system?
