LonWorks Gateway Wiring Reserved C R Lon+ Lon- Reserved X Y E No. Name 1 POWER 2 XYE 3 LON+ LON- 4 SVC1 SVC2 5 RST1 RST2 Remarks 24VAC, 50/60Hz, 200mA To ODU XYE port LON bus port to BMS Service indicator light Reset indicator light The LonWorks gateway has one set of XYE communication ports, which can be connected to one XYE bus: up to 32 IDUs (address range: 0-31), and 32 ODUs (8 refrigeration systems, address range: 00-31). The LonWorks gateway has one LON bus port, with the channel type TP/FT-10, and it is connected to the LonWorks BAS network using a free topology twisted pair. The communication distance of the LON bus and the XYE bus is 800 meters in theory, but this is affected by the actual installation environment and other factors, so the actual communication distance may vary according to circumstances. 2 IV. Functions of LonWorks Gateway The LonWorks gateway is embedded with a LonWorks function module that supports the LonTalk protocol. The LonWorks gateway can transform 485 communication protocol into a standard LonTalk protocol, thus achieving integration between the central air conditioning system and LonWorks' BAS. V. LonWorks Communication Objects of LonWorks Gateway 1. Communication Objects The new LonWorks gateway supports a total of 512 objects which can be connected to 32 IDUs and 32 ODUs. The specific parameters are shown in the following table. 2.

In these cases, refer to the error on the unit. For the meaning of a specific error code, see the explanation provided in the service manual. Error codes 121-140 are only used for the debugging function. Codes 141-240 indicate a reserved error, and 241-255 indicate reserved byte. 5 2.2 Input Class Variable (Writable) There are four kinds of LonWorks objects in the IDU, which can be used by the host of the LonWorks BAS. 1) Setting the mode Variable name: nvi_Op_Mode Parameter definition: 0 1 2 3 Mode 4 5 6 7 8 9 30 Off (Heating/water heating off for European three-pipe models) Fan on Cooling on Heating on Reservation on Heating water on Dry on Heating/heating water on Heating off Heating water off Auto Note: M represents the IDU address, nvi_Op_Mode _1 represents the mode setting of IDU #0, and so on.

By default, the mode setting is processed as mode + boot. If the upper computer sends a value that is not defined, mode setting is not performed by default. 2) Setting the fan speed Variable name: nvi_Fan_Speed Parameter definition: 6 0 1 2 3 4 Fan 5 speed 6 7 20 21 22 30 Fan off Fan speed 1 Fan speed 2 Fan speed 3 Fan speed 4 Fan speed 5 Fan speed 6 Fan speed 7 Low Medium High Automatic Note: M represents the IDU address, nvi_Fan_Speed_1 represents the fan speed setting of IDU #0, and so on. Of these, nvi_Fan_Speed _1 to nvi_Fan_Speed_16 of the sub0 main board represent the fan speed settings of IDUs #0-15 IDUs, and nvi_Fan_Speed _16 to nvi_Fan_Speed_32 of the sub1 main board represent the fan speed settings of IDUs #16-31. If the upper computer sends a value that is not defined, the fan speed setting is not performed by default. If nvi_Op_Mode_M selects the Off or Dry mode, the set values of nvi_Fan_Speed_M are invalid. If nvi_Op_Mode_M selects the Heating mode, the IDU may not be able to respond to medium/high speed commands due to the cold air protection function. 3) Setting the temperature Set temperature/automatic mode cooling set temperature/hydraulic module heating water temperature(Common IDU: 17°C to 30°C; high-temperature hydraulic module: 25°C to 80°C) Variable name: nvi_TempSet_M Parameter definition: Note: M represents the IDU address, nvi_TempSet _1 represents the temperature setting of IDU #0, and so on.

When the upper computer sends a value other than the defined values, the minimum temperature is implemented if the value is below the minimum value, while the maximum temperature is implemented if the value is higher than the maximum temperature. If the upper computer sends a temperature value with decimal places, only the integer is used. For example, 67.68°C is sent as 67°C. If nvi_TempSet _M selects the Off or Fan mode, the set values of nvi_TempSet _M are invalid. 7 4) Setting the heating temperature Automatic heating temperature/hydraulic module heating temperature (Common IDU: 17°C to 30°C; high-temperature hydraulic module: 25°C to 80°C) Variable name: nvi_Heating_Set_M Parameter definition: Temperature (Celsius) 17 18 19 20 21 22 23 24 Value - LonMaker 17 18 19 20 21 22 23 24 Temperature (Celsius) 25 26 27 28 29 30 80 Value - LonMaker 25 26 27 28 29 30 80 Note: M represents the IDU address, nvi_Heating_Set _1 represents the temperature setting of IDU #0, and so on.
