First of all, wiring, according to manual 4.5.1 chapter or 4.5.2 chapter wiring, the two wiring methods can be. Use the 4.5.1 section connection method, terminal resistor FX3U-485ADP-MB built-in dial switch dial 110 ohm; using 4.5.2 section connection method, terminal resistor FX3U-485ADP-MB built-in dial switch dial 330 ohm.
Thank you for your information on MITSUBISHI electric automation products

Then, set parameters:
Main station PLC: refer to manual 11.1 chapters, the first two lines of procedures, with M8411 normally open contact as the condition, through the MOV instruction to D8400 and D8401 assignment. MODBUS RTU mode master D8401 sets H1, that is, MOV H1 D8401. (about D8400 later.)
From station PLC: refer to manual 11.2 chapter, the first three lines of procedures, with M8411 normally open contact as the condition, through the MOV

D8400's content reference manual, chapter 6.2. D8400 contains 16 bits, these 16 bits from high to low mark b15~b0.
B0 is the data length, b0=0 is 7 bit data length, and b0=1 is 8 bit data length. Note that when you use the RTU schema, the data length should be set as
8, that is, b0=1.
B2 and B1 corresponding checksum settings, b2=0, b1=0 is no checksum; b2=0, b1=1 when the odd checksum; b2=1, b1=

OK, that's all clear. Can you explain the instructions of ADPRW in detail? I think you seem to explain it on the example of the communication manual, very well, thank you! There are some special signs, can you also explain?!

Now D8400, D8401, D8414, M8411 and other meaning through your explanation, I understand, down to ask: what is the D8402, D8403, D8404, D8405, D8406, D8407, D8409, D8410, D8411, D8412 and other means? General should be how to set? And so on? What about M8029, M8401, M8402, M8403, M8408, M8409?
The main thing is this ADPRW
