14 Cyclic Data Transfer - ProfiNet
Measuring data and status information from the DAD is sent cyclic to the PLC as a complete data package.
Simple commands (Tare, zero, etc) are also sent as cyclic data from the PLC to the DAD. An additional
mechanism in the cyclic data transfer allow the PLC to send commands to the DAD and the reply to be sent
back to the PLC. Please note that these commands can also be send as acyclic data.
