Daikin ACS320 - Group 53: EFB Protocol

Group 53: EFB Protocol
This group denes set-up variables used for an embedded eldbus (EFB) communication protocol. Refer to
communication protocol documentation for more information on these parameters.
Table 47: Group 53: EFB Protocol
Code Description Range Resolution Default S
5301 EFB PROTOCOL ID
0000…
FFFF hex
1 0000 hex
Contains the identication and program revision of the protocol.
• Format: XXYY, where xx = protocol ID, and YY = program revision.
5302 EFB STATION ID 0… 65535 1 1

Denes the node address of the RS485 link.
• The node address on each unit must be unique.
Daikin MicroTech III controls the following:
• Address 1 = SAF
• Address 2 = RAF or EAF
• Address 3 = Energy Recovery Wheel
5303 EFB BAUD RATE
1.2… 76.8
kbits/s
— 9.6 kbits/s
Denes 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
76.8 kbits/s
5304 EFB PARITY 0…3 0
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 = 8N1 – 8 data bits, No parity, one stop bit.
1 = 8N2 – 8 data bits, No parity, two stop bits.
2 = 8E1 – 8 data bits, Even parity, one stop bit.
3 = 8O1 – 8 data bits, Odd parity, one stop bit.
