Group 53: EFB Protocol
This group defines set-up variables used for an embedded fieldbus (EFB)
communication protocol. Refer to communication protocol documentation for more
information on these parameters.
Group 53: EFB Control
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
9
Defines the node address of the RS485 link.
• The node address on each unit must be unique.
5303
EFB BAUD RATE
1.2…57.6 kbits/s
-
9.6 kbits/s
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
5304
EFB PARITY
0…3
0
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.
5305
EFB CTRL PROFILE
0, 1
1
0
Selects the communication 1=ACH550 profile used by the EFB protocol.
0 =
ABB
DRIVES
– Operation of Control Word and Status Word conforms to ABB Drives Profile.
1 =
ACH
550 – Alternate 32 bit profile (Advanced users only).
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.
5309
EFB STATUS
0…7
1
0
Contains the status of the EFB protocol.
0 =
IDLE
– EFB protocol is configured, but not receiving any messages.
1 =
EXEC
.
INIT
– EFB protocol is initializing.
2 =
TIME
OUT
– A timeout has occurred in the communication between the network master and the EFB protocol.
3 =
CONFIG
ERROR
– EFB protocol has a configuration error.
4 =
OFF
-
LINE
– EFB protocol is receiving messages that are NOT addressed to this drive.
5 =
ON
-
LINE
– EFB protocol is receiving messages that are addressed to this drive.
6 =
RESET
– EFB protocol is performing a hardware reset.
7 =
LISTEN
ONLY
– EFB protocol is in listen-only mode.
