Startup and Operation5-25.1 Startup Operation of Cyclic Communication5.1.1 When FP0H is OriginatorWhen the FP0H is originator, the FP0H operates in the following order after it is powered on.Power ONResolves IP address.Starts each communicationapplication task.Starts EtherNet/IP task.Connects to targets according toScan List.Starts sending/receiving data fromtargets whose connection areestablished.Refreshes the data received byFP0H from targets.Communications with all targets arenormally performed.IP address fixed flag(R9342) turns ON.EtherNet/IP preparationdone flag (R9350) turns ON.The corresponding bits ofcyclic communicationnormal node tables turn ON.EtherNet/IP all nodes normalcommunication active relay(R9351) turns ON.Resolved.Started.Refreshed.All nodes arecommunicating.KEY POINTS• For confirming if the connection with each target is established or not,check "Cyclic communication normal node table". The cycliccommunication state node table can be read by F465 ETSTAT instruction.The communication state of each connection can be checked.• For confirming that the connections with all targets have been established,check the all nodes normal communication active relay (R9351).
