ACH550 E-Clipse Bypass User’s Manual 2-81
Embedded fieldbus
Embedded fieldbus
Overview
The ABB E-Clipse bypass can be set up to accept control for the ACH550 drive and/
or the E-Clipse Bypass from an external system using standard serial
communication protocols. When using serial communication, the ABB E-Clipse
bypass can:
• Receive system control information from the fieldbus,
• Receive drive only 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 EIA 485 interface at terminals X2:26…30
on the control board, a control system can communicate with the system using:
– Modbus® - RTU EIA 485
– Metasys® N2 EIA 485
– APOGEE® FLN
– BACnet® MS/TP EIA 485
• Fieldbus adapter (FBA) – See Fieldbus adapter on page 2-199.
NOTE: Throughout this manual, references to parameters pertain to parameters and
adjustments in the ABB E-Clipse Bypass.
Unless specifically called-out as drive parameters, all parameter adjustments are in
the ABB E-Clipse bypass.
In this document any references to “system” refers to ABB E-Clipse Bypass and
ACH550 drive.
