1. Open up the computer properties on the node to be used as the Server and as the Viewer. Verify that each computer name of these nodes is less than 14 characters, and does not contain any special or reserved characters such as “-“, “*”, “/”, etc. It is allowable to have underscore characters “_”. It is important to validate that you have a valid node name otherwise the CIMPLICITY router may fail to start.
2. Check the registration on the Server (Start> Programs> CIMPLICITY> HMI> Registration): The registration must be either “Server Development” or “Server Runtime.” Check the registration on the Viewer: The registration must be “Server Development,” “Server Runtime,” “Viewer Development,” or “Viewer Runtime.”
NOTE: Viewer-Server communications will not work if either the Server or Viewer is unlicensed and running in the 2-hour demo mode.
3. Verify that the Version and the Service Pack running on the Server and the Viewer are the same. You can check this via the CIMPLICITY workbench or CimView by going to “Help>About”.
4. On the CIMPLICITY Server running the project, verify that the “Enable Project Broadcast” option is checked on the “Options” tab in the Project Properties dialogue (Project>Properties… in the Workbench).
5. Verify the following options have been checked on the “Startup Options” tab in the Cimplicity Options dialogue (Start>Programs>CIMPLICITY>HMI>CIMPLICITY Options), on both the Server and the Viewer.
