Importing a project from <strong>RSView</strong>32, SE, or ME<br />

To use a project from <strong>RSView</strong>32, <strong>RSView</strong> <strong>Supervisory</strong> <strong>Edition</strong>, or<br />

<strong>RSView</strong> Machine <strong>Edition</strong> as the basis for a new HMI server, click<br />

Import a project.<br />

After you have copied a project into the new HMI server, changes<br />

made to the original project do not affect the copy, or vice versa.<br />

Attaching to an existing HMI server<br />

To connect to an existing HMI server without making a copy of the<br />

HMI server, click Attach to an existing HMI server.<br />

IMPORTANT<br />

You cannot attach to an existing HMI server if the HMI<br />

server is used in another application.<br />

When to use additional HMI or data servers<br />

A distributed application does not require more than one HMI server<br />

or data server, but there are circumstances in which it is helpful, for<br />

example to provide redundant operation for HMI servers or data<br />

servers at run time, or to allow different integrators to work on<br />

different HMI servers without worrying about name collisions or<br />

needing to integrate all the files later.<br />

Adding HMI servers or data servers for redundant operation<br />

You can set up redundant HMI servers or data servers to enable an<br />

application to use a secondary server in the event that the primary<br />

server goes out of service.<br />

You must set up redundancy separately for each HMI server or data<br />

server in an application.<br />

• For details about adding HMI servers to an application, see<br />
