I’m using the palletizer Powerpac option with one project and one flow.

The projects starting/stopping and the flow start/stop/recovery is being controlled by the PLC.

The customer wants to hide the pendant away from the operators and have all control on the HMI. The problem is when I stop the slow using stop option “Stop Immediately” and then try to recover the flow to restart a layer I get a UIMessageBox on the teach pendant that asks you to verify the cause of the stop is removed and then press ok to confirm.

Is there a way of recovering the flow from a error state without having confirm on the teach pendant ?

If the HMI is using the PC SDK, you can follow these instructions:
