Integrated robot control using manufacturing message specification protocol based on NetBIOS

An implementation of Manufacturing Message Specification (MMS) protocol has been made for control based on a token-ring personal computer (PC) network using NetBIOS. This paper discusses the construction of the MMS protocol data unit (PDU) and virtual manufacturing device (VMD) which are essential elements in the protocol. The session layer capability of the NetBIOS protocol provides a good basis for establishing the confirmed services in MMS. The services are implemented by utilizing the extensive session control functions in NetBIOS and building on top the required presentation and application elements.
