Divelbiss announced the introduction of its HEC-P2000 series of IoT-enabled (Internet of Things) controllers for harsh environments, including support for the SAE J1939 and NMEA 2000 serial protocols.

The controllers are programmed using the Divelbiss' free-of-charge EZ Ladder toolkit, supporting programming languages such as Ladder Diagram, Function Block, and Structured Text, based on the P-Series PLC-on-a-chip (Programmable Logic Controller) technology. The series allows controlling mobile equipment, communicating with various serial protocols such as CAN Bus, SAE J1939, and NMEA 2000. It supports logging system data or adding Internet-of-Things (IoT) capability to existing systems.

The sealed NEMA 4 enclosure design allows operation in 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 Bus and serial ports can 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 “Slave."

The serial ports are also programmable via the Structured Text programming language, allowing the implementation of custom protocols, making them suitable for communicating with bar code scanners, RFID readers, and other serial devices.

The CAN Bus port supports the SAE J1939 and NMEA 2000 protocols. In support of IoT, the HEC-P2000 series comes with cellular-capable models for communicating with Cloud Portal Solutions. A plug-in GPS module is accessible for connection to the serial port (EIA-232) for global positioning and time syncing of the onboard Real Time Clock.

For applications requiring data logging, the product offers an internal SD card. This feature provides the user options for implementing data-logging with timestamps to the SD card. When utilized with the Cloud Portal Solutions, the controllers can communicate data to the cloud, where it is timestamped and stored in the cloud database for later viewing, analysis, and export. The product supports a power supply range from 9 VDC to 32 VDC. It has an extended operating temperature range of -40 °C to +80 °C, making it suitable for applications with extreme environmental requirements.

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

PICAN-M - NMEA 0183 And NMEA 2000 HAT For Raspberry Pi

The PICAN-M (M = Marine) is a Raspberry Pi HAT with NMEA 0183 and NMEA 2000 connection. The NMEA 0183 (RS422) port is accessible via a 5-way screw terminal. The NMEA 2000 port is accessible via a Micro-C connector.

The board comes with a 3A SMPS (Switch Mode Power Supply), allowing to power the Raspberry Pi plus HAT from an onboard power source (12 VDC).

The board works with software suites such as OpenPCN, OpenPlotter, Signal K, and CANBoat.
