Practically is not possible. Always should have "something" between both HMIs. |

Hello, Is it a real or Hypothetical question? If you would like to communicate between 2 HMI stations, then we have two options:
This because HMI doesn't have an internal memory to transmit from or to. You write on HMI an Input field for instance to write it in certain address of the CPU or you can read this address from PLC on HMI output field. So, the question is not HMI-HMI communication coz there should be CPUs in the system. Back to above options:
Hope this helps. |
