Description

The ISIT J1939 stack is available in both single-channel and multi-channel CAN versions, supporting the implementation of multiple Application Controllers (ACs) on a single ECU.
Thanks to its modular architecture, the stack can be tailored to specific requirements in terms of CPU, memory, number of messages (PGNs), CAN networks, and additional supported protocols. It also integrates seamlessly with extended protocols such as:
  • Transport Protocols (ISO-TP)
  • Diagnostics (DiagOnCAN, UDS)
  • Proprietary extensions
The stack manages key J1939 functions such as Address Claiming, NAME management, command messages, and transport protocols (BAM, P2P). It supports both event-driven and periodic PGNs for transmission and reception, ensuring flexibility across diverse applications. ISIT J1939 protocol Stack - Features and Benefits
  • Full support for Address Claiming and NAME management
  • Integrated Transport Protocols (BAM, P2P)
  • Supports periodic and event-driven PGN transmission/reception
  • Multi-channel CAN support
  • Multiple Application Controllers per ECU
  • Openness to parallel protocols (ISO-TP, UDS, DiagOnCAN, proprietary)
  • Includes Stack Configuration Editor (with Source code generator).
  • Additional Services:
    • Development support and integration assistance
    • J1939 protocol training for teams and developers

ISIT FSoE protocol Stack Safety over EtherCAT

ISIT's Safety over EtherCAT (FSoE) protocol stack adds certified safety communication to your applications in full compliance with the IEC 61784-3-12 standard. It is tailored for systems that require functional safety at the communication layer. Fail-Safe over EtherCAT (FSoE) is a cornerstone of modern industrial automation. By ensuring safe and reliable data exchange, FSoE plays a vital role in maintaining the integrity of industrial processes.

Communication layers of FSoE:
  • EtherCAT (Layer 2): Provides a fast and efficient communication backbone between industrial devices.
  • FSoE Protocol (Layer 7): Dedicated to safety and reliability, introducing advanced mechanisms that guarantee safe and predictable data exchange.
With ISIT’s FSoE stack, devices can exchange safety data seamlessly over EtherCAT while leveraging built-in fault detection mechanisms. This ensures a high level of safety, quick fault response, and maximum process uptime.

Benefits of FSoE
  • Proactive fault detection enhances overall system reliability.
  • Built-in safety mechanisms maintain secure operation even in communication fault conditions.
  • Rapid fault response minimizes safety risks.
ISIT FSoE Stack : Features and Benefits
  • Seamless integration of safety communication over EtherCAT networks.
  • Pre-certified for IEC 61508 up to SIL 3 (depending on architecture).
  • Modular design, adaptable to project-specific needs.
  • Available in both Master (Main-instance) and Slave (Sub-instance) versions.
  • Generic, easy-to-use programming interface.
  • Compatible with most EtherCAT Master and Slave protocol stacks.
  • Certifiable against additional standards (IEC 62304, DO-178, etc.).

ISIT CANopen Safety Certifiable stack

SIL 2 / SIL 3 – Ready-to-Use CANopen Safety Stack With the ISIT CANopen Safety Certifiable protocol stack (ISIT_COSAFE_LC), ISIT takes system safety a step further by offering the only “ready-to-use” IEC61508 pre-certified CANopen stack (with Safety extension) on the market, delivered together with a certification pack. Fully compliant with EN 50325-5, it enables rapid, and cost-effective integration.

This solution makes it possible to integrate CANopen into products subject to stringent safety standards such as IEC 61508, DO-178C, ISO 26262, or ECSS-E-ST-50-15C, up to the highest certification levels (e.g., SIL 3 or DAL A). Compared to proprietary developments, ISIT’s solution offers unmatched ROI and thus significantly reduced time-to-certification. Designed for Safety Applications

Safety-critical systems must comply with rigorous standards and obtain certification from independent bodies, an inherently complex, lengthy, and costly process. ISIT simplifies this challenge by combining deep expertise in industrial protocols, embedded systems, and certification requirements into a streamlined, certifiable solution.

To address diverse industrial fields and varying levels of safety requirements, ISIT provides a scalable architecture. Built on a common code base, it allows certification at multiple levels and offers seamless evolution toward higher safety requirements, without the need to modify the protocol layer. ISIT CANopen Safety Certifiable protocol Stack - Key Features and Benefits
  • Pre-certified COTS software for IEC 61508 up to SIL 3 / ISO 13849 PL d.
  • Fully compliant with CANopen CiA-301 (EN 50325-4) and Safety extension CiA-304 (EN 50325-5).
  • Available in both Master and Slave versions.
  • Delivered with a Certification Pack (documentation, test reports and certificate).
  • Available for different OS- and CPU architectures (certified on a specific reference platform).
  • Protocol stack delivered as source code.
ISIT also offers 2 others versions of its CANopen stack: ISIT CANopen Stack ISIT CANopen Safety Stack
