1. Modbus Configuration
1.1. Modbus type selection. Select RTU, TCP or simultaneous RTU and TCP communication.
2. TCP Configuration.
2.1. Modbus TCP Port: Modbus TCP communication port setting. Default port 502.
2.2. Keep Alive. Set the time of inactivity to send a keep Alive message. Default 10 minutes.
3. RTU Configuration.
3.1. RTU bus connection type. Select the RTU connection type serial bus RS485 or 232.
3.2 Baudrate. Set the RTU bus communication speed. Default: 9600 bps.
•
Available values: 1200, 2400, 4800, 9600,19200, 38400, 57600, 115200 bps.
3.3 Data Type. Set the Data-bit/parity/stop-bit. Default: 8bit/None/1.
•
Available selection: 8bit/None/1, 8bit/Even/1, 8bit/Odd/1, 8bit/None/2.
3.4 Slave Number. Set the Modbus Slave address. Default slave address: 1.
•
Valid address: 1...255.
3.5 Ambient temperature provided from Modbus. This option enables a Modbus register to receive an
ambient temperature from Modbus to regulate the AC unit using Virtual Temperature function.
Case 1: Temperature setpoint IS NOT provided from Modbus. (Checkbox deactivated).
In this case, the user setpoint is directly applied to the AC unit. Setpoint control and ambient temperature is
based on the following registers:
([IU] * 100) +
(([L] - 1) * 10000) + 4
([IU] * 100) +
(([L]- 1) * 10000) + 5
•
Register 4: Temperature Setpoint (x10)
This register can write the desired user setpoint and will be updated with the current setpoint in the AC unit
at any time.
•
Register 5: Ambient temperature (x10)
This register can be read only and will inform about the ambient temperature measured by the AC unit
temperature probe, which usually corresponds with the temperature measured in the return path. See AC
settings for further information.
Case 2: Temperature setpoint IS provided from Modbus (use Virtual temperature) (Checkbox
activated)
This feaure is provided to be used only in the following cases:
•
There is no setpoint control from BMS or centralized system in parallel to the Intesis device.
•
There is no setpoint control from RC, infrared remote or any other AC optional which allow
setpoint management.
Considerning these sentences, the resulting system is that in which the setpoint control is only performed
through the Intesis gateway.
Enabling this feature will add two additional Modbus temperature registers to the previous list:
