Page 8: System Overview Profinet
System overview PROFINET System overview PROFINET Beckhoff components PROFINET is the open Industrial Ethernet-standard of the PNO (PROFINET user organization). PROFINET IO describes the exchange of data between controllers and field devices in several real-time classes: RT (software-based real-time) and IRT (hardware-supported isochronous real-time). In addition, further Ethernet traffic can be transmitted in the NRT (non-real-time) time slot of the PROFINET cycle. - Page 9 System overview PROFINET Beckhoff PROFINET components Components Comment Embedded PCs Embedded PC with PROFINET RT Device fieldbus CX8093 interface Embedded PC with optional interface CX50xx-M930 PROFINET RT Controller Embedded PC with optional PROFINET RT Device CX50xx-B930 interface EtherCAT terminals PROFINET IO controller...

Page 11: Connection And Cabling
Connection and cabling Connection and cabling PROFINET connection The latest generation of Embedded PCs can be ordered with the optional PROFINET interface (M930/B930). Both Ethernet interfaces are switched and dependent on each other. The optional interface X300 is identified as X300 on the devices and has as black border to identify it. In a PROFINET slave the incoming PROFINET signal is connected to the upper port of the X300 interface. -
Page 12: Cabling
Connection and cabling Cabling Transmission standards 10Base5 The transmission medium for 10Base5 consists of a thick coaxial cable ("yellow cable") with a max. transmission speed of 10 Mbaud arranged in a line topology with branches (drops) each of which is connected to one network device. Because all the devices are in this case connected to a common transmission medium, it is inevitable that collisions occur often in 10Base5. -
Page 13: Topology
Connection and cabling Shielded twisted pair Describes a cable with an outer screen, without defining the nature of the screen any more closely. S/STP Screened/shielded twisted pair (wires are individually screened) This identification refers to a cable with a screen for each of the two wires as well as an outer shield. Industrial Twisted-Pair The structure is similar to that of S/STP, but, in contrast to S/STP, it has only one pair of conductors. -

Page 20: Sync Task
TwinCAT tabs 4.3.2 Sync Task The SyncTask triggers the PROFINET task and thus the speed with which the PROFINET communication operates. Pay attention to the system utilization rate of your Embedded PCs. The shorter the PROFINET cycle time is, the higher the total system utilization rate will be. A very high system utilization rate can lead to an ADS connection no longer being triggered often enough and this connection may be interrupted. -
