The cloud manufacturing (CloudM) resource access solution of Internet of Things (IOT) application was discussed. According to resource access requirements, a kind of CloudM resource access architecture based on IOT was described, as well as several key technologies in the architecture. Several key issues such as classification of resource information accesses, access processes were studied. Related explanations about QoS information expanding, manufacturing capacity information constructing, EPC information collection were illustrated. With magnetic bearing as an example, its conceptual information model and QoS expanded information described by PML were given.
