Fiosrachadh coitcheann
Fiosrachadh coitcheann mu 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.
Chan urrainnear barrachd air dà uèir a cheangal ri gach ceann-uidhe, a’ dèanamh cinnteach gun cleachdar rèiteachadh “Daisy Chain” (ann an sreath) no “loidhne dhìreach” (dìreach). Chan eilear a’ moladh ceangal rionnag no lìonra (fosgailte), oir faodaidh faileasan taobh a-staigh a’ chàball truailleadh dàta adhbhrachadh.
Rèiteachadh
- 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.
AN AIRE:
There may be additional protection requirements for the entire installation and configuration, which the installer/programmer is responsible for maintaining.
Obrachadh lìonra MODBUS RTU - Modh tràilleachd
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.
- A’ toirt cothrom dha na h-uile tags and data used in the controller’s ladder program.
- Seòladh tràillean 8-bit
- Meud dàta 32-bit (seòladh 1 = tilleadh dàta 32-bit)
- Each MODBUS data register has a size of 2 bytes.
AN AIRE:
- 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).
AN AIRE:
- Connecting unconfigured controllers to the RS-485 network will result in improper operation.
- Dlighe-sgrìobhaidh - Chan fhaodar an sgrìobhainn seo ath-riochdachadh agus a sgaoileadh ach le cead sònraichte bho Engo Controls agus chan fhaodar a thoirt seachad ach do dhaoine ùghdarraichte no do chompanaidhean leis an eòlas teignigeach a tha a dhìth.

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. (Paraimeadairean stàlaidh -P16) |

Ceistean Cumanta
- 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.
