Commands

By way of Command input, you can first send a Select and then an Operate to data points. The SBO timeout can be configured in the driver configuration. After sending a Select, a counter starts running. After the configured SBO timeout has passed, a COT_actterm with a set PN bit will be sent back. If the Select action is cancelled, a COT_deact will be sent back to notify you of this. After the SBO timeout has passed, a COT_deactcon will be sent. If you send an Operate within the timeout, the procedure will stay as usual.
