The Issue is that buttons don't change the value in the plc and indicators don't display the state of tags in the plc. I have attached a picture of the set up for the connection. I can both ping and download to both the PLC and HMI and they show up with green checkmarks in the hardware config with I go online with them. The HMI also has yellow triangles with exclamation points over the buttons. Any help is appreciated. Attachment HMI Connection 1.PNG (73 Downloads)

I did just factory reset everything and commission the equipment again and got the same results. I was think the issue might be related to the device name for the HMI. These unified comfort panels have the ports (X1P1 & X1P2 share one network, X2P1 is on its own network). The PLC and my PC are physically connected to X1P1 through a unmanaged ethernet switch.

I think this looks correct now but I want back and forth a few times on it. Attachment Device Names 1.PNG (48 Downloads)

Put a cable from X1 of the HMI to X1 of the PLC directly to test.

	Obrigado.
