CAN und CANopen

Standardized access to device parameters

The neMESYS syringe pumps are connected via the CAN bus and use the CANopen protocol for standardized access to all device parameters. Each neMESYS pump has an RS232-CAN gateway. You connect the RS232 interface of your microcontroller only to the first neMESYS pump and have access to all pumps on the bus via the internal gateway. In our Open Source RS232 library we have already programmed the RS232 communication for you.

If your microcontroller has a CAN interface, you can also access the CAN bus of the neMESYS pumps directly. Optimal integration is achieved by using a CANopen master stack such as the open source CANopen stack CANopen Node.

RS232 Library

You get the complete source code

Other device manufacturers disclose the serial protocol of their pumps - we go one step further. CETONI offers a comprehensive RS232 C-library for integration of neMESYS pumps into customised microcontroller based control solutions.

Highlights

  • you get the complete C source code
  • well defined application programming interface (API)
  • clearly arranged groups of functions
  • well documented source code
  • controls a number of pumps via one single serial interface

CAN Power Cable or RS232 Power Cable

For CAN bus or RS232 and power supply

With the appropriate adapter cable you simply connect your CETONI devices to the CAN bus or RS232 interface of your controller. The 24V for the power supply of the CETONI devices can be connected via the two cable strands.
