[Development of a CAN (controller area network) bus for modules of a perfused cell culture system]

For computer-aided data acquisition and automated running of experiments in cell cultivation reactors networking of all sensoric and actoric devices is required. A low cost and high performance solution to this demand can be found by using the widely established CAN (Controller Area Network) bus. If standard PCs running MS Windows are used to control this network special measures have to be taken to prevent loss of data caused by differences in the computing power of the PC on one hand and microcontroller-based devices on the other.
