Overview
Embedded Fieldbus
Overview
The ACH550 can be set up to accept control from an external system using standard
serial communication protocols. When using serial communication, the ACH550 can
either:
• Receive all of its control information from the fieldbus, or
• Be controlled from some combination of fieldbus control and other available
control locations, such as digital or analog inputs, and the control panel.
Two basic serial communications configurations are available:
• Embedded fieldbus (EFB) – Using the RS485 interface at terminals X1:28…32 on
the control board, a control system can communicate with the drive using the
Modbus® protocol. (For protocol and profile descriptions, see "Modbus Protocol
Technical Data", "ABB Control Profiles Technical Data", etc. starting on page 19.):
– Modbus®
– Metasys® N2
– APOGEE® FLN
–BACnet®
• Fieldbus adapter (FBA) – See ACH550 User’s Manual.
