4.4 FlexLogic design using Engineer
Parts of EnerVista Viewpoint Engineer software are integrated in the EnerVista UR Setup software. Engineer can be used to
create and modify FlexLogic that is used by a device, such as to monitor output, monitor triggers, and create self-tests.
Automatically displays existing FlexLogic
Open multiple tabs and edit simultaneously
Display symbols in IEC, ISO, or UR formats
Export a diagram as BMP file or copy it to the clipboard for import into other applications
Scale and print files in various paper sizes
Works with all UR firmware versions
The figure shows an example where several inputs are used to trigger an output. With the OR function, any one of the
inputs can trigger the output.
