This paper discusses a new solution for IGMP (Internet Group Management Protocol) for PLC (Programmable Logic Controller) in intelligent manufacturing system. It is based on the study of a new PLC design with an Ethernet switch device 88E6165 embedded in it. The switch passes IGMP traffic from the external switch ports to the CPU (Central Processing Unit) for snooping and forwarding via the CPU Ethernet interface. The architecture of multi hosts in the intelligent manufacturing system is given in the paper. The use case(s), actors and process are also analyzed to perform the switch operations with IGMP. This process uses a switch manager to perform a manager role to periodically query all devices in the subnet and subsequently. It causes devices to re-join the multicast group of listeners for any stream in which they may be interested.
