context_page_description: Hermes is a machine-to-machine communication standard used in the SMT assembly industry.
  It is a successor to the SMEMA standard, introducing improvements such as: simpler physical wiring, use of popular data transmission formats, reduced number of barcode scanners, transmission of board data to downstream machines.
  By the end of 2018 IPC has confirmed to recognize The Hermes Standard to be the successor to “the SMEMA Standard” IPC-SMEMA-9851, which has been the only globally accepted and broadly established standard for machine to machine communication in SMT with regards to PCB handover. Accordingly, The Hermes Standard was assigned an IPC naming code: It can now officially be referred to as IPC-HERMES-9852.
  The actual version, IPC-HERMES-9852, version 1.2 provides an electrical SMEMA interface replacement and extends the interface to communicate such things as unique identifiers for handled printed boards, equipment identifiers of the first machine noticing a printed board, barcodes, conveyor speed and specific information about the product type.

  It is a successor to the SMEMA standard, introducing improvements such as: simpler physical wiring (Ethernet), use of popular data transmission formats (TCP/IP and XML), reduced number of barcode scanners (required only once at the beginning of the line), transmission of board data (such as barcodes & dimensions) to downstream machines.
