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.
Code Description
5301 EFB PROTOCOL ID
Contains the identification and program revision of the protocol.
• Format: XXYY, where xx = protocol ID, and YY = program revision.
5302 EFB STATION ID
Defines the node address of the RS485 link.
• The node address on each unit must be unique.
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
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 1 – 8 data bits, No parity, one stop bit.
N
1 = 8 2 – 8 data bits, No parity, two stop bits.
N
2 = 8 1 – 8 data bits, Even parity, one stop bit.
E
3 = 8 1 – 8 data bits, Odd parity, one stop bit.
O
5305 EFB CTRL PROFILE
Selects the communication profile used by the EFB protocol.
0 = – Operation of Control Word and Status Word conforms to ABB Drives Profile.
ABB DRIVES
1 = 550
ACS
5306 EFB OK MESSAGES
Contains a count of valid messages received by the drive.
• During normal operation, this counter is increasing constantly.
5307 EFB CRC ERRORS
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
Contains a count of the messages with a character error received by the drive.
5309 EFB STATUS
Contains the status of the EFB protocol.
0 = – EFB protocol is not configured.
IDLE
1 = . – EFB protocol is initializing.
EXEC INIT
2 = – A timeout has occurred in the communication between the network master and the EFB protocol.
TIME OUT
3 = – EFB protocol has a configuration error.
CONFIG ERROR
4 = - – EFB protocol is off-line.
OFF LINE
5 = - – EFB protocol is on-line.
ON LINE
6 = – EFB protocol is performing a hardware reset.
RESET
7 = – EFB protocol is in listen-only mode.
LISTEN ONLY
5310 EFB PAR 10
Specifies the parameter mapped to Modbus Register 40005.
5311 EFB PAR 11
Specifies the parameter mapped to Modbus Register 40006.
