DAE AIR CON communication driverí»s read schedule 

Read schedule setting parameters are as follows:

1) STATION – Controller address = 0 ~ 19.

2) Read Command – Command = ?1.

3) Read Start Address Don't care.

4) Save start address for Communication Server – Saving start address of Communication Server.

5) Read Size – Fixed to 1. ( read 19 item data. refer to <Table 1> )

2. Writing settings

You can control HVAC setting value by using write settings.

 

Bit Write

Word write setting parameters are as follows:

1)  PORT              Port no. (0 ~ 255)

2)  STATION        Controller address = 0 ~ 19.

3)  ADDRESS      Don't care.

4)  Extra1             Write command = PARA.

5)  Extra2            Write command = ON or OFF : Run/Stop Command,

2 : Setting temperature Add or Decraese( ON = Add, Off = Decrease ),

3 : Deviation temperature Add or Decraese( ON = Add, Off = Decrease ),

4 : Setting humidity Add or Decraese( ON = Add, Off = Decrease ),

5 : Deviation humidity Add or Decraese( ON = Add, Off = Decrease ).

 

Write example 1)

 Port : 0, Station : 0,  Address : 0,  Extra1 : ON,  Extra2 :

The setting parameter shown above is an example of Run control of 0  DAE AIR CON controller address.

 

Write example 2)

 Port : 0, Station : 0,  Address : 0,  Extra1 : 2 ,  Extra2 :

The setting parameter shown above is an example of setting temperature Add(ON) or Decraese(OFF) of 0  DAE AIR CON controller address.

 

Write example 3)

Port : 0, Station : 0,  Address : 0,  Extra1 : 4 ,  Extra2 :

The setting parameter shown above is an example of setting humidity Add(ON) or Decraese(OFF) of 0  DAE AIR CON controller address.

 

Word Write

Word write and bit write have the same setting parameters except output value.
