Embedded fieldbus
5303 EFB BAUD RATE
Defines the communication
speed of the RS485 link in
kbits per second (kbits/s).
1.2 kbits/s
2.4 kbits/s
4.8 kbits/s
9.6 kbits/s
19.2 kbits/s
38.4 kbits/s
57.6 kbits/s
76.8 kbits/s
When this protocol is
selected, the default
value for this
parameter is: 9.6
When this protocol is selected, the
default value for this parameter is:
38400
5304 EFB PARITY
Defines the data length, parity
and stop bits to be used with
the RS485 link communication.
• The same settings must be
used in all on-line stations.
0 = 8
N1 – 8 data bits, No parity,
one stop bit.
1 = 8N2 – 8 data bits, No parity,
two stop bits.
2 = 8
E1 – 8 data bits, Even
parity, one stop bit.
3 = 8O1 – 8 data bits, Odd
parity, one stop bit.
When this protocol is
selected, the default
value for this
parameter is: 1
When this protocol is selected, the
default value for this parameter is: 0
Do not edit.
5305 EFB CTRL PROFILE
Selects the communication
profile used by the EFB
protocol.
0 =
ABB DRV LIM – Operation of
Control/Status Words
conform to ABB Drives
Profile (limited), as used in
ACQ550.
1 =
DCU PROFILE – Operation of
Control/Status Words
conform to 32-bit DCU
Profile.
2 =
ABB DRV FULL – Operation
of Control/Status Words
conform to ABB Drives
Profile (full).
When this protocol is
selected, the default
value for this
parameter is: 0
N/A. When this protocol is selected,
the default value for this parameter
is: 0
Changing the value for this
parameter has no affect on this
protocol’s behavior.
5306 EFB OK MESSAGES This parameter indicates the number of valid application
messages received at this drive. This count does not
include MS/TP token passing and polling messages. (For
such messages, see 5316).
5307 EFB CRC ERRORS This parameter indicates the number of CRC errors
detected, in either the header or data CRCs.
5308 EFB UART ERRORS This parameter indicates the number of UART-related errors
(framing, parity) detected.
