    Hi and welcome! yes, you can connect two (not more) ADP communication modules on the left side of the main unit. For example two FX3U-485ADP-MB.

    Hi kaare_t. Thanks for replying. I have been reading the manual (Data Communication Edition) and trying to parameterize the two channels, one for Modbus Master and other for Non-protocol Communication or as Modbus Slave but unable to do so.

    I figured that I cannot use Modbus Master and Modbus Slave together even if I have two separate adapters, as the Modbus serial line is shared and Channel1 takes over, disabling Channel2.

    I am gonna contact my supplier if he can give a solution, otherwise I think I am going to buy a FX3U-232ADP-MB and a CNV-BD card.

    Please do tell me with little details if I can use my existing two 485ADP-MB adapters for my application.

    Thanks

    Is it possible to use FX3U-485ADP-MB as a serial port to send and receive user defined string/data to and from a computer?

    I have a FX3U-32M PLC and two FX3U-485ADP-MB adapters. I have been using PLC with one adapter as Modbus Master. Now i want to use both adapters, where one will be Modbus Master as usual and the other I want to use to send and receive data to and from computer terminal (Example - Realterm). I have a third party 232/485 converter which works really well.

    Lets me just describe my requirement straight forward. I want to display process parameters on a windows computer based user interface (UI) and also set some variables in PLC from the same UI. The UI has access to serial ports of computer.
