How do I he FX3U-485ADP-MB FX3U-485ADP-MB FX3U-485ADP-MB instruction ADPRW? Do not order communication protocol and third party equipment instrument, with the RS2 instruction has been successful communication, now just want to use the ADPRW command to newsletter, please advice! Thank you

You can look at the following link posts, a more detailed summary of the FX3U-485ADP-MB MODBUS communication function to do the use of methods.

Hello! Thank you very much, I see the link in the post, I have the following questions puzzled now: I am FX3U-485ADP-MB and absolute encoder communication, communication parameters can be set in the system parameters, so that you do not need to set the D8420. The encoder is MODBUS RTU protocol. The message format is: the host request reads the current value: address, command word, parameter, address, data length, check code (01H 04)

Using the ADPRW instruction parameter must be set in the corresponding special register, and no arguments can be set in the software.
In the case above, the ADPRW directive writes ADPRW H1 H4 H1 H2 D0.

Which particular register is the check code written on?!
