J1939 and NMEA 2000

Harsh environment control and IoT connectivity

Divelbiss announced the introduction of the HEC-P2000 series of IoT-enabled (Internet of Things) controllers for harsh environments. They support J1939 and NMEA 2000.

The controllers are programmed using the company’s free EZ Ladder toolkit in programming languages Ladder Diagram, Function Block, and Structured Text, based on the P-Series PLC-on-a-chip (programmable logic controller) technology. The series enables controlling mobile equipment, communicating with various serial bus protocols such as CAN, J1939, NMEA 2000, logging system data, or adding Internet of Things (IoT) capability to existing systems.

Featuring a sealed NEMA 4 enclosure that is designed for the harsh duty commonly found in mobile environments, the controllers have an I/O count with eight digital inputs, three high speed counter inputs, a quadrature encoder interface, and eight digital outputs rated for 2-A each (of which all are PWM capable). If additional I/O is required, the CAN and serial ports may be utilized to communicate to expansion I/O. The controllers feature two serial ports (one EIA-232 and one EIA-485) which supports Modbus RTU/ASCII protocols as either a so-called “master” or a “slave” device./p>

The serial ports are also directly programmable via the Structured Text programming language, allowing the implementation of custom protocols, which makes them suitable for communicating to bar code scanners, RFID readers, or other serial devices.

The CAN port fully supports the J1939 and NMEA 2000 protocols. The HEC-P2000 series has cellular-capable models for communicating with the Cloud Portal Solutions. A plug-in GPS module is available for connection to the serial port (EIA-232) for global positioning and time syncing of the on-board Real Time Clock.

For applications that require data logging, the product supports an internal SD card. This feature gives the user options for implementing data-logging with time stamps to the SD card. When utilized with the Cloud Portal Solutions, the controllers can communicate data to the cloud, where it is date/time stamped and stored in the cloud database for later viewing, analysis, and export. The product supports supply voltages from 9 VDC to 32 VDC and have an operating temperature range of -40 °C to +80 °C, making it suitable for use in applications with extreme environmental requirements.

The series gives the user the ability to provide machine control, data-logging, and IoT connectivity to applications in the mobile, industrial, environmental, agricultural, construction, and other markets.
