PROFINET IO - GENERAL INFOPROFINET IO defines the communication with decentrally connected peripheral devices.It defines the entire data exchange between IO-controllers (devices with "master functionality") andthe IO-devices (devices with "slave functionality"), as well as parameter setting and diagnosis.PROFINET IO is designed for the fast data exchange between Ethernet-based field devices andfollows the provider-consumer model.2.1 PROFINET IO protocolTable 2.Connections andcommunicationsInterface 100BaseTX, IEEE 802.3 compatibleData transfer method Ethernet half/full -duplexData transfer speed 10/100 MBit/s, autosensingProtocol PROFINET IOConnector Shielded RJ45 connectorCable type CAT5e STPDefault IP Selectable: Fixed or DHCPTable 3.

However, real-time process control requires the Full-duplex mode and the 100-megabit speed. Drives must beconnected to the Ethernet network with a Shielded Twisted Pair (STP) CAT-5e cable (or better). Useonly industrial standard components in the network and avoid complex structures to minimize thelength of response time and the amount of incorrect dispatches.2.3 ACD (Address Conflict Detection) in Ethernet networks.The VACON ® 100 implements ACD algorithm (IETF RFC 5227).The ACD algorithm tries to actively detect if the IP address configured to this device is been used byanother device in the same network. To accomplish this, ACD sends four ARP request packets whenthe device's Ethernet interface goes up or when its IP address changes. ACD prevents the use of theEthernet interface until the ARP probing finishes. This delays the startup of fieldbus protocols aboutone second.
