Ernestas Posted September 6, 2019 Report Posted September 6, 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. Quote
Gambit Posted September 6, 2019 Report Posted September 6, 2019 You should use a multidrop unit. GT01-RS4-M Quote
Gambit Posted September 6, 2019 Report Posted September 6, 2019 (edited) 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 https://www.mitsubishielectric.com/dl/fa/document/manual/got/sh081197eng/sh081197engab.pdf 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 laterhttp://dl.mitsubishielectric.co.jp/dl/fa/document/catalog/plc_fx/l51/l51-a.pdf Edited September 6, 2019 by Gambit Quote
