4 Communication settings and guide of HMI connecting with controller
◆Frequency of R W 0 m apping : If input 2000 to R W 0, frequency is 25H Z, and input 4000, frequency
is 50HZ, and so on.
◆Tim er, send value of R W 1 and R W 0 to R W D 8000.
Modbus RTU Protocol:
Device Bit Address Word Address Format Notes
Output bit 0X1-65535 ------ DDDDD
Input bit (read only) 1X1-65535 ------ DDDDD
Input Register (read only) ------ 3X1-65535 DDDDD
Output Register ------ 4X1-65535 DDDDD
Note：
Mapping of address (same as *10 relationships):
2-01 is to 4X2010
3-02 is to 4X3020
So address 4X1300 is to 1-30 as following picture, here is double word address. To get more
information, please refer to danfoss manual.
In addition, to get mapping address of startup, you should set bit of 3, 4, 5, 6,7,11 coil on:
0x047C=0000 0100 0111 1100
Set 0X 3, 0X 4, 0X 5, 0X 6, 0X 7, 0X 11 all to “1” (if random one of these registers is “0”,inverter will
stop.
