5.2 Performance and Functions of FP75-35.2 Performance and Functions of FP7For using the EtherNet/IP function on the FP7, the following functions can be used.5.2.1 IGMP QueryWith this function, the FP7 checks periodically in which host group each EtherNet/IP device isregistered on a LAN.This function can be used when an Ethernet switch HUB with the multicast filter function andany devices which send an IGMP query do not exist in the network.5.2.2 TTLTTL (Time To Live) is used to set the hierarchies of the network in which transmission packetscan live when sending multicast packets to another scanner.5.2.3 MulticastData of one target can be sent to multiple originators.
