By enabling the “Stop prevention function you have the possibility to prevent the acquisition being stopped by accident.

You can enable the stop prevention by selecting any digital signal. If attempts to stop the acquisition occur on an ibaPDA client while the signal is TRUE, a message box pops up asking for confirmation. Only if you answer this question with “Yes” the acquisition will be stopped. Using this feature you can protect a running acquisition with signals from the plant, the process or by an operation.

Lock signal

Select the appropriate signal from the signal tree in the drop-down list.

All digital signals can be used as lock signal, e. g.

• Digital input signals from sensors or PLC

• ibaQPanel inputs

• Virtual signals

Warning text

You can overwrite or modify the standard text in this field. This helps you to include practical advice, directions or contact data in the warning message.

If the stop prevention is triggered by clicking on the < button STOP, the warning message pops up immediately after confirmation of the stop request.

If the stop prevention is triggered by a change of the I/O configuration, the warning message pops up, supplemented by an entry in the validation dialog.
