Smart Embedded Systems SES

14+ years · Industrial Automation & Process · Pioneering HART & APL
Smart Embedded Systems (SES) has been in business for over 14 years and for all these years, company has been a key player for offering various leading edge products and technologies for the industrial automation and process. SES was the first company to have offered HART modem(1200 & 9600 bps) and HART stack on a single chip.

With the advent of new standard, APL (Advanced Physical Layer). SES has been on forefront of offerings once again products which help accelerate the growth of digital transformation.
In industrial networking, Advanced Physical Layer (APL) and HART solve different problems and are often complementary rather than direct competitors.

HART

  • "add digital intelligence to analog instruments."
  • Extensive 4–20 mA infrastructure
  • Low-cost upgrades and diagnostics
  • Modest bandwidth needs
widely deployed

APL

  • "bring Ethernet directly to field instruments."
  • Building a new digital plant
  • Richer telemetry, analytics, edge/cloud integration
  • Large-scale industrial IoT and future expansion

Market drivers

  • Devices becoming more complex
    • Memory - higher density and lower cost.
    • Variables – HART now has 8, dual measurements.
    • Smarter – additional calculations, alerts, compensations, off-sets, etc.
    • Memory - higher density and lower cost.
    • More Data – storage history, trends, signatures, curves, as-found/as-left.
    • Diagnostics – smarter and more intuitive.
  • IoT Cloud connectivity and data integration
  • Digital transformation – get right info to right place at the right time
  • Security – AES 128 bit encryption (not required in HART Specification)
  • Future Proof - Easy to upgrade for fixes in the future
  • Flexibility – Dual Speed and Multiple Modem applications
  • Interoperability – open system initiatives

Compliance with HART standards

  • Defined in HART 6 Specification – Released in 2001
    • 9600 baud – Phase Shift Key not cost-effective to implement – until now!
  • Users looking for faster speeds driven by digital transformation
  • Backward compatible with HART 1200 bps modem
  • Ethernet may be fast enough but requires a different infrastructure
    • Ethernet considered a disruptive solution – eliminates the 4-20mA plant standard.
  • HART is well established, field proven and easy to use
  • Staff is trained throughout the entire device life cycle
  • Easy to implement on host systems and devices of all types
  • Dual Speed is an ADDITIVE solution – not a DISRUPTIVE solution

Who benefits

  • Device and Host Suppliers - a future-proof path forward
    • Marketing – fast data transfer for complex devices.
    • Engineering – simplified design with soft dual speed modem.
    • Production – faster, lower cost, reduced number of components.
    • Sales – early adopters get a competitive advantage.
  • End Users
    • Works with existing infrastructure – tools, training, work processes, etc.
    • Faster data transfers for complex devices.
    • Lower operations costs and reduced unscheduled downtime.
    • Reduces the risk of moving away from HART / 4-20mA standard.
  • Engineering Contractors
    • Universal product application - no engineering practice changes.
    • Lower risk - maintains the 4-20mA power and wiring standard.
