The remote office can monitor the HMI using “HMI Viewer” while one or more smartphones are connected to the HMI using VNC. To allow multiple devices to connect to the HMI using VNC, please ensure that “VNC multi-connection” is enabled:
Each client that connects to the HMI using EasyAccess 2.0 should have their own account on the domain. You cannot login to the same account on multiple devices. Additionally, I would recommend that the end customer does not monitor the HMI continuously as this can use a lot of data.
Each HMI on the domain is allotted 1GB of free high speed data each month. If the customer’s data usage surpasses the 1GB of free high speed data, the connection speed will be slowed significantly. A top-up card can be used to replenish data in the event that the data usage exceeds this threshold.
The reason that we do not typically recommend connecting multiple VNC clients to one device is that each client will have to share control with the operator. For example: If client 1 changes to a “Trend” screen, client 2 and the operator will see this change as well. Similarly, if the operator clicks a return button to return to the home page, client 1 and client 2 will see this change as well.
