Questions & Answers
1. About The Hermes Standard
The Hermes Standard offers a non-proprietary, vendor-independent protocol for machine-to-machine (M2M) communication in SMT assembly. Its target is to improve board flow management and traceability through all stations of a SMT line.
Based on TCP/IP and XML The Hermes Standard uses modern communication technology and standardized data formats for M2M communication. Its purpose is to transmit barcode information and board or job related data such as dimensions, board identifiers and product type identifiers together with the board along the machines of different vendors in a SMT line.
The Hermes Standard for vendor independent machine-to-machine communication in SMT assembly has been worked out by an initiative of industry experts, setting the base line for an open, cross-vendor protocol. This initiative of equal members meets on a regular base with the goal to enrich the standard and form a foundation for Industy-4.0 solutions. Each of them can propose and determine amendments for future standardization. The Hermes Standard Initiative is neither a legal nor a commercial subject. There is no profit motive. The representative of the initiative is the elected chair.
Going for an initiative rather than an IPC working group allows all members to be fast and close to the application. The initiative members can focus on driving the content of the standard rather than struggling with a cumbersome standardization process.
According to Wikipedia “Hermes” is an Olympian god in Greek religion and mythology, the son of Zeus. Hermes is considered a god of transitions and boundaries. He is described as quick and cunning, moving freely between the worlds. He is also portrayed as an emissary and messenger of the gods.
2. The Hermes Standard for electronics manufacturers
The Hermes Standard helps to optimize your production in many terms. It reduces equipment invest, line length as well as the need for operator interaction with the SMT line.
All of this is achieved by forwarding board related information together with the board along the equipment within a SMT line. With The Hermes Standard maximum one barcode scanner is required in the line. Besides this, the product itself becomes the driver of changes along the SMT line. As example the manual adjustment of conveyor belt widths belongs to the past. Likewise, the information provided with a board can be used to automatically change the program according to the product type.
In addition, The Hermes Standard forms the base for continuous tracing of boards throughout a SMT line. Thereby, it provides the essential backbone of any Industry 4.0 solution and the feature set can be enriched over time.
First solutions based on the new protocol are announced for Productronica trade fair end of 2017. In addition to that, some initiative members are planning to provide upgrade kits for their existing equipment in the field to support this new standard.
16 leading equipment suppliers have initially teamed up in The Hermes Standard Initiative – and further will follow: ASM AS GmbH, ASYS Automatisierungssysteme GmbH, CYBEROPTICS, ERSA GmbH, KIC, KOH YOUNG Technology Inc., Nutek Europe B.V., MIRTEC, MYCRONIC AB, OMRON Corporation, PARMI, Rehm Thermal Systems GmbH, SAKI Corp, SMT Wertheim, VISCOM AG and YJ Link Co., Ltd.
For equipment not supporting The Hermes Standard the integration into lines with equipment supporting it is possible. In this case relevant data may have to be recovered again after equipment without The Hermes Standard onboard to leverage the benefits provided by The Hermes Standard.
Any SMT equipment supplier who wants to contribute to the further evolution of The Hermes Standard is welcome to join upcoming meetings of The Hermes Initiative. For suppliers that don´t want to spend the effort to shape the standardization the pure implementation based on the specifications published by the initiative is possible without any license fee to be paid.
The Hermes Standard drives the horizontal integration along the SMT line. The OML and CfX standard on the other hand are focusing on the vertical integration from the SMT line to an MES. Therefore the combination of both in complex production environment will be necessary in the long run. In simpler environments with less demand in terms of process data, traceability, process interlocking … The Hermes Standard can act as standalone solution.
3. The Hermes Standard for equipment vendors
The valid version of The Hermes Standard is available for everyone for download via this website once released. The documents describing The Hermes Standard and additional support material can be found in the download section of this website.
The Hermes Standard Initiative has developed version 1.0 of The Hermes Standard without any profit motive. The Hermes Standard protocol can be used by any supplier, integrator and manufacturer as is with no license fees to be paid. No warranty of completeness and correctness is assured by the initiative. The initiative rejects any kind of liability and warranty claims arising from the use of the specification.
The proposed solution allows combining both (The Hermes Standard and SMEMA) in the same line. In order to make this happen every equipment which is ready for The Hermes Standard must be able to handle both SMEMA and The Hermes Standard protocol. This solution has been chosen in order to bridge the gap as long as not 100% of the equipment in the field is capable to cooperate based on The Hermes Standard. On long term the Hermes Standard can fully replace the classical SMEMA. Once this is achieved the support of SMEMA can be removed from the different equipment’s and the transition phase is over.
4. Active contribution to shape The Hermes Standard
The Hermes Standard Initiative is as open as The Hermes Standard itself: The initiative welcomes all equipment suppliers who want to take an active, constructive part in developing The Hermes Standard. To become a member companies just have to participate in the initiative meetings. Invitations for the meetings are sent to all interested equipment suppliers who register themselves on The Hermes Standard website accordingly.
It is expected that all members support the initiative and promote The Hermes Standard. Initiative members can actively shape the development of The Hermes Standard. The future development of the standard is driven via a discussion forum which is part of this website. This forum can only be accessed by members.
The implementation of The Hermes Standard version 1.0 is self-evident for all participants, who want to remain members of The Hermes Standard Initiative. The implementation of the revisions to version 1.0 of The Hermes Standard is also obligatory because these are error corrections. The implementation of higher versions (version 1.1 or 2.0) is not obligatory. Then only the basics functions of The Hermes Standard will be supported in such a case.
The initiative meets (at least) once a year to make respective decisions. Invitations are sent to all interested equipment suppliers who register themselves on The Hermes Standard website. Invitations to the initiative meeting are to be sent out by the chair at least 12 weeks in advance to the meeting. Who once actively participated in such a meeting is regarded as an initiative member and can vote to shape the future of The Hermes Standard.
Rules can be established or changed on initiative meetings. Proposals are to be made at least 8 weeks prior to the meeting by distribution to all initiative members. Who once actively participated in such a meeting is regarded as an initiative member and can vote to shape the future of The Hermes Standard. There is one vote per company. A majority decision will be taken by the participants present.
The Hermes Standard Initiative has a chairman (company), nominated by the initiative members. The current chairman is ASM AS GmbH represented by Thomas Bliem with a first running period until November 2017. Minimum running time after this point shall be two years.
The Hermes Standard Initiative is an equipment supplier’s collaboration. Access to initiative membership is limited to equipment suppliers only. Electronic manufacturers are welcome to the meetings to discuss individual points. Where appropriate, they are invited by the chairman to the meetings.
The understanding of the initiative is to form an open collaboration of equipment suppliers for developing a common SMT communication standard. The initiative wants to articulate common interests and help all market participants offer their customers uniform and efficient Industy-4.0-solutions. The initiative is neither a legal nor a commercial subject. There is no profit motive. The initiative members don’t want to establish a company and don’t want to enter into any contractual obligations. When the common interest is reached, the initiative shall end without any duties left.
