Daikin MD5 - Group 53: EFB Protocol

Group 53: EFB Protocol
This group denes set-up variables used for an embedded eldbus (EFB) communication protocol. The standard EFB protocol in
the MD5 is Modbus. See chapter Embedded Fieldbus on page 45.

Code Description Range Resolution Default S
5302 EFB STATION ID 0…65535
1 = SAF
2 = RAF/EAF
3 = ERW
1

Denes 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,
38.4, 57.6,
76.8 kb/s
— 9.6 kb/s
Denes 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)
Denes 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.
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 (IDLE)
Contains the status of the EFB protocol.
0 = IDLE – EFB protocol is congured, but not receiving any messages.
1 = EXECUT 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 conguration 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.
5311 EFB PAR 11 0…65535 1 0
Species the parameter mapped to Modbus Register 40006.
5312 EFB PAR 12 0…65535 1 0
Species the parameter mapped to Modbus Register 40007.
5313 EFB PAR 13 0…65535 1 0
Species the parameter mapped to Modbus Register 40008.
