When you click Add button or Edit button in dialogue box of <Figure 2>, dialogue box of <Figure 3> is shown.
You can write the setting value by using write settings.
Bit Write
Bit write and word write have the same setting parameters except output value( 0 or 1 ).
Word Write
Word write setting parameters are as follows:
1) PORT Port no. (0 ~ 255)
2) STATION Controller station number = 1 ~ 32.
3) ADDRESS Don't care.
4) Extra1 Write command = POWER, MODE, WATER, TEMP. ( Refer to <Table 3> )
5) Extra2 Don't care.
<Table 3> is range of output value and contens of write commands.
