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.

Abstract The ability to instantly and successfully interact among technical engineers, management team and machines is vital to the productivity and efficiency of manufacturing shopfloor. Chat messenger with smart mobile has obvious advantages for shopfloor management in group communication, instant notification and remote control. This paper presents a natural-language chat & control HMI for manufacturing shopfloor. The system successfully realizes a smooth two-way communication between users and shopfloor machines. Users can access just-in-time information, receive instant notifications, and remotely control shopfloor machines. All relevant parties can communicate over shopfloor matters in a chat group. The system comprises of four core modules, i.e. Chat Messenger, Chat Service Engine, Control & Communication Engine and Local Command Service. Chat Messenger provides chatting user interface and group management dealing with end-user’s enquiries and notifications via natural language. Chat Service Engine and Control & Communication Engine are two cloud-based service modules, which process questionnaire logic and transmit relevant commands and data bi-directionally between Chat Messenger and Local Command Service. Local Command Service is a local service terminal which implements interfaces and protocols directly interacting with shopfloor machines. It processes the requests and commands from Chat Messenger to shopfloor machines. It also checks real-time machine anomalies and automatically generates corresponding notifications. The system has been implemented in the advanced manufacturing shopfloor at Nanyang Polytechnic. The results and validation show the improvement of manufacturing shopfloor efficiency.
