Overview

TwinCAT PLC HMI CE is a system needed for the execution of visualizations on BECKHOFF CE-based devices generated in TwinCAT PLC Control.

If a control program contains associated visualizations these are displayed in full screen mode when the TwinCAT PLC HMI CE is available on CE based systems.

The user can operate the control and monitoring functions contained in the underlying project via the mouse or the keyboard. This is possible even if the TwinCAT PLC project file is read-protected. However, the user cannot edit the control program and no menus or toolbars are available, i.e., only pure 'operation' of the visualization elements is available.

The main control and monitoring functions for a project intended for the operator version therefore must be associated with the visualization elements during project creation and operated in online mode. A special input facility is available for this purpose in the configuration dialog for a visualization element.

By seamlessly integrating the development platform for the visualization masks into the PLC programming system TwinCAT PLC HMI CE offers advantages other visualizations simply cannot come up to:

• A tag list of the variables to be used is not needed. It is possible to work directly with the TwinCAT PLC Control variables.
• Variable values in input fields can be modified by expressions (e.g., “Variable1+ Variable2 * 12 + 5”)
• A mighty place-holder concept allows the user to create object-oriented masks.
