FX3U GOT2000 RS485 Setting

6 posts in this topic

Guys, I'm using PLC (FX3U-64M) to communicate with HMI (GT2308-VTBA) using expansion board (FX3U-485-BD). Since the PLC is at the site and I don't have actual PLC to test. May I ask the parameters that I had configured below are correct?

Why GOT side doesn't have data length, parity and stop bit to configure?

I assume that in your case the PLC built in RS-422 port is bussy...

I don't thik  FX3U-485-BD can communicate with GT23.

The right expansion board is  FX3U-422-BD.

If the distance is long (> 30 meters), It would be an good idea to add an inexpensive FX3U-ENET-ADP module and set the communication to Ethernet.
When inserting a simple Hub this could also be usefull for programming the PLC

Even if I'm using FX3U-422-BD expansion board, the GOT setting side still doesn't have data bits, parity and stop bit. RS232 also the same. Anyone knows why?

On youtube, someone is using FX3U to communicate with other brand HMI by using FX3U-485-BD. In the video, the HMI got the data bits, parity and stop bit setting. However, in my case why GOT side doesn't have it? Did I configure the wrong setting?

Good day.

Even manual is not needed.

Mitsubishi devices use native communication protocol (HMI/PLC/inverters/servos). Just setup in GOT and  FX proper  hardware connection type, and connect by proper cabel. No matter it is 422/485/232
