Hello There,
In my control panel, port 1 or RS232 port of a 1747-NET-AIC is connected to a compactlogic l32e and DH-485 or port 3 of the converter is connected to a HMI.
The HMI used Modbus RTU protocol to get the data into the HMI components. One HMI communicates well without any issues. But i must add the second HMI to display the same details.
I connected another pair of wires to the DH-485 port A and B pins of the same 1747-net-aic and terminated to RS232 port of the second HMI but now i only see some values in both HMIs
Can I split the DH-485 signal this way is it correct?
I appreciate your answers.
Thanks
