Embedded fieldbus
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 any of
the following protocols:
– Modbus®
– Metasys® N2
– APOGEE® FLN
– BACnet®
• Fieldbus adapter (FBA) – See section Fieldbus adapter on page 1-259.
