Embedded fieldbus
Communication setup – EFB
Serial communication selection
To activate the serial communication, set parameter 9802
COMM PROTOCOL SEL
=
• 1 (
STD MODBUS
).
• 2 (
N
2)
• 3 (
FLN
)
• 5 (
BACNET
)
Note:
If you cannot see the desired selection on the panel, your drive does not have
that protocol software in the application memory.
Serial communication configuration
Setting 9802 automatically sets the appropriate default values in parameters that
define the communication process. These parameters and descriptions are defined
below. In particular, note that the station ID may require adjustment.
Code Description
EFB Protocol Reference
Modbus N2 FLN BACnet
5301 EFB PROTOCOL ID
Contains the identification and
program revision of the
protocol.
Do not edit. Any non-zero value entered for parameter 9802
COMM PROT SEL, sets this parameter automatically. The
format is: XXYY, where xx = protocol ID, and YY = program
revision.
5302 EFB STATION ID
Defines the node address of
the RS485 link.
When one of these protocols is
selected, the default value for
this parameter is: 1
When this protocol is
selected, the default
value for this parameter
is: 128
Set each drive on the network with a unique value for this
parameter.
Note:
For a new address to take affect, the drive power
must be cycled
OR
5302 must first be set to 0 before
selecting a new address. Leaving 5302 = 0 places the
RS485 channel in reset, disabling communication.
Note:
For the BACnet protocol, the ACH550 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 behavior.
