- Configuration of the EFAN-24 controller must be carried out by a qualified person with appropriate authorization and technical knowledge, following country and EU standards and regulations.
- Failure to adhere to instructions may void the manufacturer’s responsibility.
- The controller can operate as a slave in a MODBUS RTU network with specific features and communication requirements. Ensure proper wiring configuration to avoid data corruption.
- Network Connection: RS-485 serial interface
- Data Configuration: Address, speed, and format are determined by hardware
- Data Access: Full access to the controller’s ladder program data
- Ka nui o ka ʻikepili: 2 bytes no ka papa inoa ʻikepili MODBUS
- Before connecting the controller to the RS-485 network, ensure proper configuration of communication settings, including address, baud rate, parity, and stop bits.
- Unconfigured controllers should not be connected to the network to avoid operational issues.
ʻIke nui
ʻIke nui e pili ana i MODBUS RTU
The MODBUS RTU structure uses a master-slave system to exchange messages. It allows a maximum of 247 slaves, but only one master. The master controls the operation of the network, and only it sends the request. Slaves do not undertake transmissions on their own. Each communication begins with the master requesting the Slave, which responds to the master with what it has been asked. The master (computer) communicates with slaves (controllers) in two-wire RS-485 mode. This uses data lines A+ and B- for data exchange, which MUST be one twisted pair.

Hoʻonohonoho
- Configuration must be carried out by a qualified person with the appropriate authorization and technical knowledge, following the standards and regulations of the country and the EU.
- The manufacturer will not be held responsible for any conduct not following the instructions.
NĀ MEA:
There may be additional protection requirements for the entire installation and configuration, which the installer/programmer is responsible for maintaining.
ʻO ka hana pūnaewele MODBUS RTU - Ke ʻano kauā
Engo’s MODBUS controller has the following features when operating as a slave in a MODBUS RTU network:
- Network connection via RS-485 serial interface.
- Address, communication speed, and byte format are determined by hardware configuration.
- Hāʻawi i ke komo i nā mea a pau tags and data used in the controller’s ladder program.
- Helu kauā 8-bit
- Nui ʻikepili 32-bit (1 helu helu = 32-bit hoʻihoʻi ʻikepili)
- Each MODBUS data register has a size of 2 bytes.
NĀ MEA:
- Before the controller is connected to the RS-485 network, it must first be properly configured.
- The communication settings are configured in the service parameters of the regulator (device).
NĀ MEA:
- Connecting unconfigured controllers to the RS-485 network will result in improper operation.

Allow fan operation dependent on the temperature measurement on the pipe. For example, if the temperature on the pipe is too low, and the controller is in heating mode
– The pipe sensor will not allow the fan to run. The change of heating/cooling is done manually, using the buttons. Values for fan control based on pipe temperature are set in parameters P17 and P18. |

ΔT of 0- 10V valve operation
This parameter is responsible for the modulated 0- 10V output of the valve. – In heating mode: If the room temperature drops, the valve opens proportionally to the delta size. – In cooling mode: If the room temperature increases, the valve opens in proportion to the size of the delta. The valve opening starts from the room set temperature. (Installer parameters -P17) |

FAN delta algorithm for cooling
The parameter determines the width of the temperature range in which the fan operates in cooling mode. If the room temperature increases, then: 1. When a small value of Delta FAN, the faster the response of the fan to a change in temperature temperature – faster the increase in speed.
2. When large value of Delta FAN, the slower fan increases speed. (Nā palena hoʻokomo -P16) |

FAQ
- Q: What are the default communication settings for the EFAN-24 controller?
- A: The default settings include a slave device address of 1, the baud rate of 9600, no parity bit, and one stop bit.
- Q: How can I access different data registers in the MODBUS RTU network?
- A: Use the appropriate function codes such as #03 for reading holding registers or #06 for writing a single register. Each register has specific data values related to controller parameters.
