2-150 ACH550 E-Clipse Bypass User’s Manual
Embedded fieldbus
Note: The system will function as a master with MAC IDs in the range of 1-127. With
MAC ID settings of 128-254, the drive is in slave only mode.
Changes made to drive parameter Group 53, EFB Protocol, do not take affect until
you perform one of the following:
• Cycle the bypass power OFF and ON, or
• Set bypass parameter 5302 to 0, and then back to a unique MAC ID, or
• Use the ReinitializeDevice service.
Quick-start sequence - drive communications
The following steps summarize the process for enabling and configuring BACnet on
the ABB E-Clipse Bypass:
1. Enable BACnet protocol: Set bypass parameter 9802,
COMM PROTOCOL SEL BACNET
(5).
• To confirm this selection, read bypass parameter 5301,
EFB PROTOCOL ID. It
should read x5xx (where “x” is any value).
2. Place the BACnet channel in “reset”: Set bypass parameter 5302,
EFB STATION ID = 0.
• This setting holds the BACnet communication channel in reset while remaining
settings are completed.
3. Define the MS/TP baud rate.
• Set bypass parameter 5303,
EFB BAUD RATE = appropriate value
4. Define the Device Object instance.
• To define a specific device object instance value, use bypass parameters 5311
and 5317 (object instance values must be unique and in the range 1 to
4,194,303).
• To use the bypass’ MS/TP MAC ID as the device object instance value, set
bypass parameter 5311 and 5317 = 0.
• BACnet requires a unique Device Object ID for each device on the BACnet
network.
5316 EFB PAR 16 0 This parameter indicates the count of MS/TP
tokens passed to this drive.
5317 EFB PAR 17 0 This parameter works with paramter 5311 to set
BACnet instance IDs. See parameter 5311.

5320
EFB PAR 18…20 N/A - Not supported with BACnet protocol.
