52 SMT007 MAGAZINE I MARCH 2020 1. A message protocol using AMQP 2. An encoding mechanism using JSON 3. A specific content creation element- structured topics and messages The Hermes standard is a low-level line con- trol protocol that passes information up and down the equipment line, including PCB ID, program name, and key product data. These elements allow for the creation of automatic decision-making and dashboard displays, alerts, and reports. Applications that improve productivity, efficiency, capacity planning, and quality while lowering costs. It allows the full traceability of components (IPC-1782) and feedback to design (IPC-2581). Typical CFX topics and messages are seen in Figure 2. The IPC has established a methodol- ogy to add and edit new messages for the CFX standard, the "CFX message submission pro- cess," to allow it to grow and be applied by more machines and processes. There are even CFX messaging for hand soldering. To facilitate adapting machines and appli- cations, there are free software development kits (SDK) available for Windows, .Net, Linux, LabVIEW, JAVA, etc. Already, hundreds of machines have been adapted and demoed with native CFX. The goal of the IPC Committee is to facilitate a fully functioning Industry 4.0 digital manufacturing world. Closed-loop feedback in real-time is now possible and available. IPC-CFX provides the tools and community to implement most of the goals of the smart factory, including DFX feedback via IPC-2581's digital product model (DPM) back to design. An integral part of the success of IPC-CFX is the DPM standard cre- ated by IPC-2581. OML OML was developed by the Valor Division of Mentor, which is now part of Siemens. OML is the messaging and communications proto- cols used by the Valor IoT box according to the ISA-95 application hierarchy (Figure 3) to con- nect SMT assembly equipment to the Siemens higher-level factory software and to displays and performance dashboards. Hardware There are two unique pieces of "plug and play" hardware in Siemens' IoT solution. They are: • System processing unit (SPU): The factory gateway for networking and line controller for connections to machines Figure 2: CFX messaging. (Source: IPC)
