SMEMA Hermes Adaptor

With the release of the IPC-HERMES-9852 Standard and its intent to replace the existing SMEMA standard, SMT manufacturers require an upgrade path for their existing equipment.

Where available, an software upgrade is the obvious upgrade path for manufacturing equipment, however this may not be available for 'dumb' equipment such as conveyors.

A SMEMA Hermes Adaptor mimics the SMEMA Upline and Downline states, by retrieving the Hermes board data from the equipment previous in the line, and retrieves the Hermes Ready, Not Ready, state from the equipment next in-line, this is then converted into SMEMA states for the legacy equipment to interpret.

The Adaptor is a hardware device that has both Upline and Downline SMEMA Connectors, an Ethernet port for Hermes connections, and runs on a Raspberry Pi. One Adaptor is required for each piece of equipment that lacks Hermes compatibility.

Configuration is conducted by a MultiPlug Extension which also handles all the Hermes software connections.

Do the adaptors still send out the SMEMA signal to the next machine down the line or does the next machine need to have an adaptor as well?

All equipment that can't be upgraded to the new Hermes standard needs its own adaptor. One adaptor per equipment.

Do you have many customers that are using the adaptors?

As the Hermes standard is still immature we only have pilot partners using the adaptor as we conduct market discovery and refine the hardware. Due to the number of enquiries we have received we are confident that there will be a need for the adaptor while PCB assembly lines are migrated to the Hermes standard.

What has been the typical reasons / benefits for using the adaptors?

The adaptors are typically being used for conveyors and out-of-support manufacturing equipment. The adaptors are extending the life of this old equipment and bridging the gap while new equipment is sourced.

Would it be possible for us to buy these units from you rebadged with our name?

We are not a hardware company so once the hardware platform is mature we are more than happy to allow others to create their own. We are considering also selling the adaptor as a kit as we feel production engineers have the skill required to assemble them.

It is possible to have some datasheet/brochure?

The adaptor's specification is in flux, so we can't provide these but we will be updating the website at every opportunity as the specifications change.

Do the adaptors support the CFX (Connected Factory Exchange) standard as well?

The short answer is you can use the CFX MultiPlug Extension to push PCB data into the CFX but you still have to use Hermes MultiPlug Extension to conduct the data connection and handshakes using Sockets and XML.

The longer answer is the Hermes standard is tightly coupled to TCP Sockets and XML, where CFX uses AMQP and Json. In the Industry 4.0 era we shouldn't be coupling ourselves to transport technologies, rather only be concerned with the data of the messages. So to answer the question it's a No, however we do predict that the standards will merge over time and this will require a software update of the adaptor but the hardware will stay the same.

Using the SMEMA Hermes Adaptor

  • Use this configuration for a situation where SMEMA equipment is being used between equipment that has been upgraded to use the IPC-HERMES-9852 standard.
  • All equipment that only operates using SMEMA will require its own Hermes adaptor hardware.
  • It is not recommended to use this configuration as a 'first step' towards migrating your PCB assembly line to the Hermes standard as every piece of equipment will require its own Hermes adaptor hardware.
  • Both Upline and Downline SMEMA connectors found on the equipment should be connected to the hardware adaptor. The adaptor will mimic the SMEMA Upline and Downline states and will update the Hermes Good-Board Failed-Board messages to reflect the SMEMA Downlines states.
  • If a board is manually added to the SMEMA enabled equipment, the software will detect this and will trigger a user prompt to enter PCB data within a web browser based user interface. PCB data can be manually entered using a keyboard or looked up using a third party data source, following either a manually typed entry of the PCB ID, or scanned using a serial or keyboard emulation barcode scanner.
  • If a board is manually removed from the SMEMA enabled equipment, the PCB queue can be updated using the web browser based user interface to reflect the change.
  • Due to the nature of the web browser based user interface, it can be accessed from mobile devices that have access to the local network or using adjacent equipment that features a web browser.

Creating a Scan Station by using the SMEMA Hermes Adaptor

  • Use this configuration for a situation where a PCB assembly line migrates into a IPC-HERMES-9852 compliant line, this maybe at the very start at the PCB loader or partway through. Also where a break in the compliance occurs and it has to be restored.
  • Only the Downline SMEMA connector found on the equipment should be connected to the hardware adaptor. The Upline SMEMA connector found on the equipment should be connected to the Upline equipment, if any.
  • By default the SMEMA ‘Machine Ready’ will be unset preventing any new PCBs from moving downline.
  • Once the PCB ID has been scanned by serial barcode scanner, the PCB values are looked up using a third party data source and the normal Hermes handshake is made with the Downline equipment.
  • Monitoring can be conducted by a web browser based user interface.
  • Due to the nature of the web browser based user interface, it can be accessed from mobile devices that have access to the local network or using adjacent equipment that features a web browser.

Using the Hermes MultiPlug Extension to capture PCB data

  • The Multiplug Fog Computing platform, along with the Multiplug Hermes and Networks Extensions can be installed onto any computer running Windows or Linux to create a Hermes Pass-through.
  • This configuration can be used for situations where the extraction of PCB data is required while a PCB is moved between the assembly line equipment.
  • A Multiplug Hermes Extension pass-through makes the equipment believe it is talking directly with the next equipment upline and downline, but in fact this configuration is creating a man-in-the-middle.
  • Extracted PCB data can be sent to other MultiPlug Extensions, for example the CFX (Connected Factory Exchange) Extension.

  • Hermes MultiPlug Extension - Core software
  • Networks MultiPlug Extension - Required for Sockets communication
