PASABAN MC-2006 03 CAN Bus Communication Card for Industrial PLC Systems

Product Overview

The PASABAN MC-2006 03 is a CAN (Controller Area Network) communication card designed for integration into PLC and industrial automation systems. This module, part of the PASABAN COM CAN series, enables PLCs to communicate over CAN bus networks, interfacing with CANopen devices, proprietary CAN-based sensors, actuators, and distributed I/O modules. The MC-2006 03 is built for reliable operation in harsh industrial environments, providing galvanic isolation between the CAN interface and the host controller. It is suitable for applications requiring real-time data exchange, such as motion control, vehicle automation, and factory floor networking where CAN bus is the preferred protocol.

Key Features of PASABAN MC-2006 03

The MC-2006 03 card supports CAN 2.0A (11-bit identifier) and CAN 2.0B (29-bit identifier) frames, allowing compatibility with both standard and extended CAN message formats. The module includes a high-speed CAN transceiver capable of baud rates up to 1 Mbps, with automatic baud rate detection or manual configuration. Onboard memory buffers can store multiple CAN messages to prevent data loss during burst transmissions. The card provides optical or magnetic isolation between the CAN bus and the host logic, protecting the PLC from ground loops and electrical transients.

The MC-2006 03 is designed for easy integration with PASABAN PLC systems or other industrial controllers via a standard backplane or cable interface. Configuration is typically performed through register mapping or dedicated software tools, allowing users to set CAN identifiers, filters, and baud rates. The card includes LED indicators for CAN bus activity, error status, and power, simplifying diagnostics. The module operates from a 24 V DC or 5 V DC supply depending on the host system. It supports both polled and interrupt-driven data transfer to minimize host processor overhead. The card is built with industrial-grade components rated for extended temperature ranges and resistance to vibration.

Functional Description

The MC-2006 03 card operates as a CAN bus interface, converting parallel data from the PLC backplane into serial CAN messages. When the host PLC writes data to the card’s output buffer, the card formats the data into CAN frames with the configured identifier and transmits them onto the bus. Conversely, incoming CAN frames that match the configured acceptance filters are stored in the input buffer, where the host PLC can read them. The card handles bit timing, arbitration, error detection, and automatic retransmission of lost messages. In the event of a bus-off condition, the card can be configured to automatically recover or notify the host PLC. The isolation barrier ensures that the host logic remains protected from bus faults, such as short circuits to high voltage. The card also supports listen-only mode for bus monitoring and analysis.

Applications

The PASABAN MC-2006 03 is used in industrial automation applications requiring CAN bus connectivity. Typical uses include connecting PLCs to CANopen drives and I/O, interfacing with vehicle networks (J1939 or CAN-based), implementing distributed control in printing and packaging machinery, and retrofitting older machines to modern PLC systems while retaining existing CAN sensors.
