1PLC & 2 HMI

Ernestas · 6 Sep 2019

Hello,

I have problem, i cant connect 2 hmi to one plc. Maybe someone can give a advice how to do this.

The first HMI and plc communicate with RS422 connection. I want to connect second HMI with the same program as first HMI.

I am beginner with mitsubishi plc and hmi,so dont blame....

I added photo of plc and hmi

Thanks for any help.

You should use a multidrop unit.

GT01-RS4-M

No only serial. For ethernet you would only need a switch!!!!

You can find more info on the multidrop unit in the GT connection manual (mitsubishi) Chapter 19

If you want to use Ethernet you can also add an FX3_ENET-ADP and connect both HMI's.
FX3G(C) Ver. 2.00 or later
