Is can nessi bus system

IS CAN NeSSI Bus System


Is can major parameters

IS CAN Major Parameters

  • The CAN communication model is described in /ISO11898-1/ and /CiA301/.

  • Single power source, co-cable was the only option considered.

  • Power bus specification is derived from commercially available IS power systems.

  • 9.5 Vdc @ 1.0 A Maximum

  • 10 Meter cable distance

  • M12, 5 circuit connector


Why only 10 meters

Why Only 10 Meters?

  • Since this system is expected to work with NAMUR IS solenoid valves, which require 7.7 volts.

  • IOMAX = 1 amp

  • VOMAX = 9.5 V

  • With typical 5% regulation, then:

  • VOTYP = 9.0 V, VOMIN = 8.6 V

  • For a 10 m @ 24 AWG, resistance is 0.87 ohms

  • 1 amp * 0.87 ohms = 0.9 V

  • Therefore, actual power delivered to the device could be:

  • VDEV MIN = 8.6 V – 0.9 V = 7.7 V

What is next

What is next?

  • Bill Seitz, President IXXAT to replace C. Menon as committee chair.

  • Sigrid Stramka, CAN in Automation, DE, assigned as CiA technical representative.

  • Next CiA WD 103/ IEEE 1451.6 teleconference to be scheduled for early June.

  • Update Draft Standard and circulate for general review & comment.

  • Develop & validate an apparatus example circuit.
