Continuous transmission of data

Continuous transmission of data

A continuous data stream is indispensable for many applications. For this purpose, the Beckhoff modules feature the "Enable send FIFO data continuous" setting in the Settings object. The internal transmit buffer of the box can be filled first by setting this switch. After that the entire contents of the buffer can be transmitted without interruption. To this end, data will be sent from the controller to the box as in a normal transmission. The data from the buffer is only sent with a rising edge of the "Send continuous" bit. If the data has been transferred, the box informs the controller by setting the "Init accepted" bit. "Init accepted" is cleared with "SendContinuous".
