ABB ACS320 - Group 53: EFB Protocol

256 Actual signals and parameters
 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.
5208
CRC ERRORS
0…65535 1 -
Number of messages with a CRC (cyclic redundancy check) error received by the
drive. If the number is high, check CRC calculation for possible errors.
Note: High electromagnetic noise levels generate errors.

5301
EFB PROTOCOL ID
0000 … FFFF hex 1 0000 hex
Contains the identification and program revision of the protocol.
Note: You can reset this parameter only with parameter 9802 COMM PROT SEL.
• Format XXYY hex, where XX = protocol ID and YY = program revision of the
protocol.
5302
EFB STATION ID
0…65535 1 1

Defines the address of the device. Two units with the same address are not allowed
on-line.
5303
EFB BAUD RATE
1.2 … 76.8 kbits/s - 9.6 kbits/s
Defines the transfer rate of the link.
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
76.8 kbits/s
5304
EFB PARITY
0…3 0
Defines the use of parity and stop bit(s) and the data length. The same setting 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.
