The process of editing an HMI screen file is different, depending on whether CMS is enabled.

Editing an HMI screen file with CMS enabled

When CMS is used, the CMS repository is the source of the HMI screen files. When editing is completed, the screen file is checked back into the CMS repository, then copied, at the users discretion, to the master location so it can be used by all the HMI Workstations that are configured to use it.

Note The system file is NOT the one used by the CIMPLICITY application, rather, it is the one stored in the HMI screens directory that also stores the .tcw file.
