NAM IL NCT-P3 Current Measurement communication driver’s read schedule
Read schedule setting parameters are as follows:
1) STATION – 0 ~ 255 controler ID.
2) Read command – Command = IT, I3, P_IT, P_I3, SC, TEMP, HUMI, IT_D, IT_T, I3_D, I3_T, PIT_D, PIT_T, PI3_D, PI3_T, STS, PORT, FAN, HEAT, H_HEAT.(Refer to <Table 1>)
3) Read Start Address – IT, I3, P_IT, P_I3, SC, TEMP, HUMI command : 0 = Phase R, 1 = Phase S, 2 = Phase T,
etc command : Don't care.
4) Save Start Address for Communication Server – Saving start address of Communication Server.
5) Read Size – Size = Fix to 1.

When you click Add button or Edit button in dialogue box of <Figure 2>, dialogue box of <Figure 3> will be shown.
You can set NCT-P3 controller 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 : 0 ~ 255 controler ID.
3) ADDRESS : P_IT, P_I3, FAN, HEAT, PORT command : 0 = Phase R, 1 = Phase S, 2 = Phase T,
etc command : Don't care.
4) EXTRA 1 : Write Command =P_IT, P_I3, FAN, HEAT, PORT, DATE, TIME.(Refer to <Table 2>)
5) EXTRA 2 : Don't care.
<Table 2> is a description of write command and write value of NAM IL NCT-P3 Current Measurement communication driver.
| Write Command | Contents | Output value | Address | Remarks |
| P_IT | Write of Peak IT value for N1L | Value of Peak IT | 0 = Phase R, 1 = Phase S, 2 = Phase T |
|
| P_I3 | Write of Peak I3 value for N1L | Value of Peak I3 | ||
| FAN | Write of Fan On Temperature | Temperature | (setting value = real value x 100) | |
