About us
At a Glance
The Debug function, or double-clicking on the TSX IBY 100 graphic module in the Control Expert configuration, is only available in online mode.
NOTE: In online mode, if your project contains an INTERBUS bus composed of a number of slaves and if its debug screen is open, there is a risk that Control Expert will close down unexpectedly when you attempt to save the project.
To avoid losing data, switch to offline mode before saving your project.
NOTE: When there are no applications in the PLC or when the PLC cycle time period is < 2 ms, the debugging screen cannot open or be refreshed. To prevent this, you must select the Periodic mode instead of Cyclic mode and manually set a period > 5ms.
