Parameters
Group 53: EFB PROTOCOL
This group defines set-up variables used for an embedded fieldbus (EFB)
communication protocol. The standard EFB protocol in the A
YK
550 is Modbus. See
chapter
.
Group 53: EFB Protocol
Code Description Range
Resolution
Default
S
5301
EFB PROTOCOL ID
0000…FFFF hex
1
0000 hex
Contains the identification and program revision of the protocol.
• Format: XXYY, where xx = protocol ID, and YY = program revision.
5302
EFB STATION ID
0…65535
1
1
Defines the node address of the RS485 link.
• The node address on each unit must be unique.
5303
EFB BAUD RATE
1.2, 2.4, 4.8, 9.6, 19.2,
-
9.6 kb/s
38.4, 57.6, 76.8 kb/s
Defines the communication speed of the RS485 link in kbits per second (kb/s).
1.2 kb/s
2.4 kb/s
4.8 kb/s
9.6 kb/s
19.2 kb/s
38.4 kb/s
57.6 kb/s
76.8 kb/s
5304
EFB PARITY
0…3
1
0 (8
NONE
1)
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
NONE
1 – 8 data bits, no parity, one stop bit.
1 = 8
NONE
2 – 8 data bits, no parity, two stop bits.
2 = 8
EVEN
1 – 8 data bits, even parity, one stop bit.
3 = 8
ODD
1 – 8 data bits, odd parity, one stop bit.
5305
EFB CTRL PROFILE
0…2
1
0 (
ABB
DRV
LIM
)
Selects the communication profile used by the EFB protocol.
0 =
ABB
DRV
LIM
– Operation of Control/Status Words conforms to ABB Drives Profile (limited), as used in A
<.
400
and A
<.
550.
1 =
DCU
PROFILE
– Operation of Control/Status Words conforms to 32-bit DCU Profile.
2 =
ABB
DRV
FULL
– Operation of Control/Status Words conforms to ABB Drives Profile (full).
5306
EFB OK MESSAGES
0…65535
1
0
Contains a count of valid messages received by the drive.
• During normal operation, this counter is increasing constantly.
5307
EFB CRC ERRORS
0…65535
1
0
Contains a count of the messages with a CRC error received by the drive. For high counts, check:
• Ambient electro-magnetic noise levels – high noise levels generate errors.
• CRC calculations for possible errors.
5308
EFB UART ERRORS
0…65535
1
0
Contains a count of the messages with a character error received by the drive.
