CoDeSys Controller Supports Up To Four CAN Bus, CANopen, SAE J1939 Channels

DSE M643 Vehicle & Off-Highway Machinery Control Systems

The  DSE M643 from Deep Sea Electronics is a controller that can be used on mobile applications across many varied industries including construction, municipal, agricultural, transport, and military. The product comes with four independent CAN Bus interfaces, each one configurable for different CAN protocols including CANopen, SAE J1939, and CAN Bus. Each of the CAN Bus protocols offers their own unique properties which can make them favorable for different uses. Having multiple CAN Bus connections also optimizes the amount of data on each bus, minimizing bus load and enabling the design engineer to produce a efficient system, said the company.

As SAE J1939 is the common protocol used to communicate with industrial engines and chassis, DSE have incorporated the built-in GUI (Graphical User Interface) offered by the Codesys 3.5-application software. This provides a simplified solution to programming by allowing the software engineer to pick functions from a list as in the example in Figure 2.

By selecting the group of required PGN’s (Parameter Group Number) from the pull down list, the signals are automatically converted to the correct units and any offset applied. This results in time saved during software development.

Programming using the open platform  Codesys 3.5 is still available in the traditional way but the above has provided a very useful, time saving resource for many J1939 users, said the company.

DSE M-Series controllers provide a number of other features which make the products suitable for a range of applications such as:

  • Configurable I/Os with inputs offering digital and analog capability and outputs offering digital, PWM, and PWMi capability
  • Current monitoring on all channels
  • 32 bit microprocessor with a 220 MHz clock speed and 4 MiB of application memory, for performance and operating response times
  • E11-R10 type approval
  • Operating temperature of -40 °C to + 85 °C
  • IP67 rating for superior protection against ingress of dust, water, and other contaminants
  • EN, ECE and ISO testing for shocks and bumps, vibration, salt spray, EMC, and electrical safety

CAN Logger 1000

CAN Logger 1000

The CANLogger1000 offers simple and user-friendly logging of data from a CAN-Bus without the use of a computer. Data are stored on a standard SD-card in a simple format such that it can be directly loaded into an analysis tool for further post processing. The logged data can be transferred to a PC using a standard mini-USB cable and requires no special software.

For advanced users, the device offers a wide range of configuration possibilities, such as message filtering, down-sampling, automatic bit-rate detection, cyclic-logging, heartbeat signal and runtime logging control. Further, recently added features include the ability to transmit up to 20 custom CAN messages (for use in e.g. OBD-II logging) and a new serial interface letting the logger act as a CAN interface for streaming real-time data (incl. integration with Wireshark via CANvas).
