6.3 Description

Current EB logic description:

The device uplink port is 22.
The business frame header uses:
- version = 0x86
- dataType = 0x01
Function Code 03 is used to read:
- 256: Refrigerated cabinet temperature
- 257: Defrost temperature
Function Code 01 is used to read a status block. The command is:
- 01 01 02 00 00 1F 39 51
- Start address: 0x0200
- Quantity: 0x001F
After Function Code 01 returns, EB writes bytes 3–6 of the status data into the application area as Uint32LE.
The thing model then extracts the following from this 32-bit status word:
- Valve status
- Fan status
- Defrost status
upPeriodIndex:70 indicates the uplink reporting period parameter position.
periodIndex:74 indicates the data acquisition period parameter position.
Parameter meanings:
- 110: Refrigerated cabinet temperature threshold
- 112: Defrost temperature threshold
- 114: Status change threshold
The parameter reporting / parameter response port is 214.
