Instant Access to CANopen with CANopen IA modules

October 11th, 2021 No comments

Earlier this year, EmSA inherited the CANopen IA product line from ESSolutions. The product line goes back about 20 years and at the time the products were based on the Philip’s XA architecture. The current products are using the NXP LPC11Cxx microcontrollers (ARM Cortex M0). Right from the beginning, EmSA provided the firmware and support software for these products making EmSA a natural candidate to continue this product line after ESSolutions discontinued their operation.

The base product is a small (31.5 x 20mm) 48pin module offering 7 configurable ports with 4 connectors each. Depending on the port number, a port can be configured to be:

  • Digital input or output (4 signals)
  • Remote access (serial UART, TTL)
  • Internal analog input (4 times 8 or 10bit resolution)
  • External analog input (4 times 12bit, I2C connected external)
  • External analog output (4 times 12bit, I2C connected external)
New CANopen IA M0 Starter Kit

At EmSA, we now continuously enhance the features of this product line. The latest firmware release V2.2 added remote access support to a host system via a serial TTL channel. This allows the module to be used as a CANopen communication processor in systems that can use a regular serial channel to communicate with the communication processor. A further enhancement added 8bit resolution access to the analog inputs (default use is 10bit resolution) now supporting a variety of CANopen joystick implementations.

An easy entry starter kit is now available, offering basic access to the functionality provided by the CANopen IA M0 module. All 48 pins of the module are made available on standard header rows, all marked with the matching pin names. For quick tests, switches and LEDs can be connected to any of those pins using jumper cables provided.

A CANopen FD version of the module is currently under development and scheduled for release early 2022.
