Dixell Ic100Cx Interface Modbus Register 262: Current weel exit Temperature

Technical Definition

The register Current weel exit Temperature at address 262 is used to monitor current weel exit Temperature on the Dixell Ic100Cx Interface.

• Protocol: Modbus RTU
• Data Type: INT16
• Unit: °C
• Access: Read Only

How to Read (Python pymodbus)

Use this code snippet to read this specific value via RS485:

from pymodbus.client.sync import ModbusSerialClient

client = ModbusSerialClient(method='rtu', port='/dev/ttyUSB0', baudrate=9600)
client.connect()

# Read Current weel exit temperature (Address: 262)
# Note: Check if your device uses 0-based or 1-based addressing
result = client.read_input_registers(address=262, count=2, unit=1)

if not result.isError():
    print(f"Raw Value: {result.registers}")
else:
    print("Error reading register")

client.close()

Integration (Home Assistant)

Paste this into your configuration.yaml:

- platform: modbus_controller
  name: "Current weel exit temperature"
  address: 262
  value_type: INT16
  unit_of_measurement: "°C"

💡 Engineer's Insight

Analysis: Dixell controller: Temperature at the exit of the cooling/heating element, measured in °C or °F. Critical for process control.

Troubleshooting: Could indicate a sensor failure, a problem with the heating/cooling system, or incorrect configuration.
