MicroCANopen Plus

European customers must order from our European store at www.canopenstore.eu.

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.

• Expedited, segmented and block-transfer SDO

• Multiple SDO servers

• SDO fully-meshed (matrix) communication setup with up to 16 nodes when used together with the Manager Add-on

• PDO with runtime-configurable event time, inhibit timer and transmission type

• SYNC PDO, both receive and transmit

• Heartbeat Generator

• Heartbeat Consumers

• Emergency Generator

• Node Guarding (select platforms)

• Non-volatile save/restore of parameters

• Code configured from EDS or DCF file with CANopenArchitectEDS

What's Included

MicroCANopen Plus is delivered with an example CiA401 (Generic I/O) implementation and drivers for NXP ARM and PCANopen Magic ProS simulation.

Additional and customized examples are available upon request and can include Device Profile Implementations such as Joysticks, Encoders (CiA406), Batteries (CiA418), Chargers (CiA419) or Elevators/Lifts (CiA417). All our examples pass the official CANopen® Conformance Test!

Full documentation is supplied. All software products include a one-year maintenance and priority support agreement that can be extended anytime.

Also included is a single licence for CANopenArchitectEDS, an EDS/DCF editor with code generation for quick stack configuration.
