HMI upgrades to J1587 protocol support
TeleflexMorse has added the SAE J1587 protocol to the communications capability of its universal automotive- and industrial-grade display, CANtrak.
TeleflexMorse has added the SAE J1587 protocol to the communications capability of its universal automotive- and industrial-grade display, CANtrak The introduction makes it simple to create instrument displays for diesel powered plant and equipment such as pumps, compressors, generators and drilling rigs - especially for the many suppliers of refurbished engines who need to interface to data using the older J1587 protocol
Users also have the option of interfacing using CANtrak's existing CANbus port and J1939 communications capability.
CANtrak's large LCD (110 x 110mm DIN-format) offers a universal human-machine interface that can provide a complete instrument panel for equipment.
Capable of displaying four instruments and alarms simultaneously, and with five user keys for accessing other engine gauges or data, the module offers a two-wire RS485 interface for connection to ECUs.
To simplify system building, the instrument is supplied with TeleflexMorse's ready-to-use "generic engine monitoring" package, GEM.
This software automatically creates highly graphical instrument clusters to display engine parameters and alarms.
It supports all the major diesel engine parameters and active fault alarms.
Engine data are displayed graphically using menu-driven screens, with a main display showing three gauges for key data, and other screens/gauges and information accessible by soft keys.
Users have a high degree of flexibility over display configuration, allowing application-specific gauges to be created.
Configuration possibilities include the selection of gauges displayed on any screen, the display of data in analogue or digital forms, graph trending, the units used, and selection of the language - with a choice of eight for the latter option.
For a refurbished engine application powering a piece of plant equipment, the default boot-up display could be set to show engine speed, plus oil pressure and coolant temperature gauges for example.
Among the J1587 data parameters supported are engine speed, torque, accelerator position, coolant temperature and level, oil temperature and pressure, battery voltage, fuel rate (instantaneous), barometric pressure, turbo/boost pressure, inlet manifold temperature, engine hours and total fuel used.
If any of the engine's active fault alarms occur, these are displayed overlaid on the gauge(s) currently being viewed, and additionally logged in the CANtrak's memory.
The software also offers the ability to manipulate data, and comes with a number of standard calculations that can be made available to end users including average fuel rate per hour.
The CANtrak 160 x 128 pixel display employs FSTN (film supertwist nematic) LCD technology for visibility in direct sunlight - with backlighting.
It offers a Deutsch connector interface to the engine, and protection to IP67, which covers immersion in water.
The display operates over a temperature range of -25 to +75C as standard, or optionally down to -40C with the aid of a heating element - supporting automotive and industrial industry requirements.
This provides support for OEMs building for harsh environments, such as offshore platforms and remote wellheads.
CANtrak LCDs equipped with J1587-compatible GEM software are available off the shelf in small quantities for development and prototyping.
