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
N
1 – 8 data bits, No parity,
one stop bit.
1 = 8
N
2 – 8 data bits, No parity,
two stop bits.
2 = 8
E
1 – 8 data bits, Even
parity, one stop bit.
3 = 8
O
1 – 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

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
ACH400/550.
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.
