fieldbus (EFB) communication protocol. Refer to the
communication protocol documentation for more information on
these parameters.
Code Description Range
5301 EFB PROTOCOL ID 0…0xFFFF
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
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,
Defines the communication speed of 38.4, 57.6, 76.8 kb/s
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
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…2
Selects the communication profile used by the EFB protocol.
0 =
ABB DRIV LIM
– Operation of the Control Word and Status Word
conforms to ABB Drives Profile, as used in ACS400.
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, as used in ACS600/800.
5306 EFB OK MESSAGES 0…65535
Contains a count of valid messages received by the drive.
• During normal operation, this counter is increasing constantly.
