Environmental policy

• Never dispose of this equipment with household waste. Electrical and electronic products contain substances that can be harmful to the environment if not properly handled. The crossed-out waste bin symbol indicates separate collection of electrical devices, which must be separated from other urban waste. For correct environmental management, at the end of its useful life the equipment should be taken to the collection centers provided for this purpose.
• The parts that make it up can be recycled. Therefore, please respect the regulations in force regarding environmental protection.
• If you replace the equipment, the original equipment must be returned to your dealer or deposited at a specialized collection center.
• Violations are subject to the penalties and measures stipulated in environmental protection law.

Modbus protocol

• Modbus is a communications protocol based on the master/slave (RTU) or client/server (TCP/IP) architecture, which physically organizes information into formats or logical groups of information.
• Each device on the Modbus network has a unique address. The primary device sends a command in a frame, which includes the address of the recipient (secondary) device(s). All devices receive the frame, but only the recipient interprets and executes the command, returning a confirmation message or an error message.
• It is possible to send information to a multitude of devices simultaneously through a frame called “Broadcast”.
• Each of the messages sent includes redundant information that ensures its integrity upon receipt. If after a certain time the primary device does not receive confirmation, it understands that an error has occurred and ends the communication.

Airzone systems
In Airzone zone systems, each main control board is a Modbus slave node with a Modbus slave address equal to the configured system address.

Aidoo
Modbus only available in Aidoo Wi-Fi and Aidoo Pro. Aidoo devices have a Modbus slave node implemented.
Aidoo has two Modbus maps for controlling the unit:

• Modbus Airzone map (only available in Aidoo Pro): It shares the same registers as Airzone systems and allows basic control of the unit, taking into account which Aidoo corresponds to zone 1.
• Modbus Aidoo Map: Allows complete control of the unit and provides unit parameter information.

MODBUS RTU
The Modbus RTU is used with physical level RS485.
Each data byte is represented by two 4-bit hexadecimal characters. The format of the frame is as follows:

The Modbus RTU parameters offered by the main control boards and by the Webserver HUB follow the following configuration:

Integration bus

Communications port speed| 19 200 bps
Communication| Half duplex
Frame length| 8 bit
Stop bit| 1 bit
Flow control| None
Parity| Par

MODBUS TCP/IP
This is a Modbus variant used for communications over TCP/IP networks, which is connected through port 502. It does not require a checksum calculation, since the lower layers already provide checksum protection.

Modbus function codes

The basic Modbus commands allow you to control a device to modify the value of any of its registers (memory space), or request the content of said registers, according to the different function codes:

Communication structure

MODBUS RTU AIRZONE
Note: Available for Airzone systems, Webserver and Aidoo Pro.
The format of the commands for read/write operations with Modbus RTU (8 bytes) is as follows:

System address| Operation code| Zone address| Register address| Data| CRC
---|---|---|---|---|---
1 byte| 1 byte| 1 byte| 1 byte| 1…2·N bytes| 2 bytes

• System address. Defines the system to be accessed. Addresses are from 1 to 247, as address 0 is reserved for transmission to all devices (Broadcast).
• Operation code. Indicates the function to be performed by the command.
• Zone address. For zone commands, this field defines the zone to which the operation is carried out. For system commands this byte is always 0.
• Register address. Indicates the address of the register to be accessed. In commands on multiple registers, defines the Start Register from which to operate consecutively.
• Data. Formed by 2 bytes (single operations) or set of 2 bytes (multiple operations) that contain the command information.
• CRC. 2 bytes are added to the end of the frame in order to detect errors in transmission or reception. The Cyclic Redundant Code (CRC) check method is used for this.

The generator polynomial is: CRC-16 = x16 + x15 + x2 + 1.

MODBUS TCP/IP AIRZONE
Note: Available for Airzone systems, Webserver and Aidoo Pro.
The format of the commands for read/write operations with Modbus TCP is as follows:

Transaction ID| Protocol identifier| Length field| System address| Operation code| Zone address| Register address| Data
---|---|---|---|---|---|---|---
2 bytes| 2 bytes| 2 bytes| 1 byte| 1 byte| 1 byte| 1 byte| 1…2·N bytes

• Transaction ID. Enables synchronization of messages between the server and the client.
• Protocol identifier. Always 0 value in Modbus TCP.
• Length field. Number of bytes in the frame.
• System address. Defines the system to be accessed. Addresses are from 1 to 247, with address 0 reserved for transmission to all devices (Broadcast).
• Operation code. Indicates the function that the command will perform.
• Zone address. For zone commands, this field defines the zone to which the operation is carried out. For system commands this byte is always 0.
• Register address. Indicates the address of the register to be accessed. In commands on multiple registers, defines the Start Register from which to operate consecutively.
• Data. Formed by 2 bytes (single operations) or set of 2 bytes (multiple operations) that contain the command information.

MODBUS RTU AIDOO
Note: Available for Aidoo Wi-Fi, Aidoo Pro, Aidoo Z-Wave and Aidoo Zigbee. The format of the commands for read/write operations is as follows (8 bytes):

Secondary address| Operation code| Register address| Data| CRC
---|---|---|---|---
1 byte| 1 byte| 2 bytes| 1…2·N bytes| 2 bytes

• Secondary address. Defines the secondary device to be accessed. Addresses are from 1 to 247, as address 0 is reserved for transmission to all devices (Broadcast).
• Operation code. Indicates the function that the command will perform.
• Register address. Indicates the address of the register to be accessed. In commands on multiple registers, defines the Start Register from which to operate consecutively.
• Data. Formed by 2 bytes (single operations) or set of 2 bytes (multiple operations) that contain the command information.
• CRC. 2 bytes are added to the end of the frame in order to detect errors in transmission or reception. The Cyclic Redundant Code (CRC) check method is used for this.

The generator polynomial is: CRC-16 = x16 + x15 + x2 + 1.

• Write to a register using a mask
  Write to register by masks allows you to operate through two masks and thus work at the bit level on a register. The first mask performs a logical multiplication (AND) on the register and the second one a logical addition (OR).
  The AND mask indicates the bits of the register that will be modified. The bits that have the value “1” in the mask will remain unchanged; while those that have a “0” will take this value. The value that the bits that are going to be modified will take will be the value that said bits have in the OR mask. Byte| Field
  ---|---
  0| System address (1-247) (0: Broadcast)

Registers

AIRZONE MODBUS RTU AND AIRZONE MODBUS TCP/IP MAP
Suitable for installations containing systems and/or Aidoo Pro.

ACCESS THE OBJECT TABLE.

• Airzone
  Note: Available for Airzone systems, Webserver.

  • System registers
    In systems, 25 16-bit input/output registers are defined.

  • Zone registers
    In the registers associated with zones, the address of the same is calculated as follows:

  • ZONE_REGISTER_ADDRESS = (BASE_ZONE x 256) + REGISTER_RELATIVE_ADDRESS
    The zone address identifies the zones associated to a unit, between 1 and 32 (up to 32* possible zones associated to the same unit). Address 127 is reserved for Broadcast to all the zones of the same unit and is only valid for write functions.
    Note: The total number of zones depends on the system (see System identification section). Fourteen 16-bit zone registers are defined.

• Aidoo
  Note: Available for Aidoo Pro systems.

  • System registers
    In systems, 3 16-bit input/output registers are defined.

  • Zone registers
    In Aidoo for direct expansion units and fancoil units, the zone address is always 1. In Aidoo for air to water units, there can be up to 2 zones. Therefore, the zone register address is calculated as follows:|
    ZONE_REGISTER_ADDRESS = (BASE_ZONE x 256) + REGISTER_RELATIVE_ADDRESS

MODBUS RTU AIDOO MAP
Only suitable for installations with Aidoo.
