Device part of <Figure 1> input Com Port(COM1), Baud Rate(9600), Parity Bit(0), Data Bit(8), Stop Bit(1) respectively, according to controller.
KACO Pawador Inverter communication driver read schedule
Read schedule setting parameters are as follows:
1) Station – 1 ~ 32 controller station number.
2) Read data type – 0 : 3000xi model = read of 3000xi identify, other model = read of inverter data,
1 ~ 3 : part 1 ~ 3 inverter data for 3000xi model.
3) Controller model – 0 : 3000xi model, 1 : 2500xi ~ 5000xi, 1501xi ~ 3501xi, etc.
4) Save start address for Communication Server – Saving start address of Communication Server.
5) Read Size – Fixed according to read data type.

KACO Pawador Inverter communication driver store the same data in WORD, DWORD, FLOAT memory, but the data format are different.
If you click the icon 
in protocol option part at
<Figure 1>, you
can see the dialogue box such as <Figure 2>. you can also set read schedule by
using this part.
