Description

Powerful and flexible CANopen compliant source code. Designed for small footprint applications. Provides an extended feature set including synchronous PDO transmit/receive, emergency objects, heartbeat consumption and non-volatile save/restore parameters.

MicroCANopen Plus is a small-footprint, commercial-grade CANopen implementation with advanced features. Ideal for situations requiring medium configurability during run-time and great performance on any type of platform, and for building networks that include manager nodes, MicroCANopen Plus provides the most flexible solution. Auto-generated configuration from the EDS/DCF file makes its setup a quick and painless one-step process.

Portable. MicroCANopen Plus is written in 100% standard ANSI C code allowing for straightforward porting. For targets without standard support packages, designers familiar with their target processor can easily perform the port themselves. Or, ask us for a quote to add support to your target!

Compact. ROM Specifications: 7K - 14K bytes (for CANopen Slaves) depending upon processor and options selected.

An Affordable Pricing Structure. MicroCANopen Plus offers a low, one-time fee and no royalties on deployed products and includes all source code with every purchase.

Manager Add-On

Extension of MicroCANopen Plus source code: adding Manager functionality. Reception and management of all Heartbeats and Emergencies, SDO Client functionality with automated identifification and scanning of newly detected nodes, LSS Master and MicroLSS Master (LSS FastScan).

OD/PDO Add-On

Extension of MicroCANopen Plus source code: adding extended PDO functionality. Dynamic PDO mapping (configure PDO contents at run-time) and multi-mapping (allow one Object Dictionary entry to be mapped to mutliple PDOs). Extended Object Dictionary access (remote access), for example using a serial port and switching between alternative Object Dictionaries, supporting different variants that can change during startup.

CiA447 Add-On

Extension of MicroCANopen Plus source code: adding CiA447 examples for the implementation of "car add-on devices". Requires MicroCANopen plus and Manager extension.

CANopenFD Add-On

Extension of MicroCANopen Plus source code: adding support for CANopenFD protocols, such as USDO, and increasing the length of PDOs to 64-bytes. Includes the manager add-on and CANopen Architect Professional.
