Control
The machine is organised around a CAN Bus. The Controller Area Network (CAN
bus) was originally developed by Robert Bosch in 1986 for automotive applications.
CAN is a robust bus standard designed to allow micro-controllers and devices to
communicate with each other in applications without a host computer or complex
dedicated wiring in between.
Each micro-controller on the CAN bus is called a ‘node’. In the PSQ160, each of the
control PCBs and the GUI have micro-controllers and are therefore nodes. Each
node has a unique number. See
and
The GUI provides overall control and user input. The other nodes control local
functions but are instructed from the GUI and sensor input:
Table 1. Node list
If a fault occurs, an error code is displayed on the GUI, for example: E38.307.0.
The first digits are the node ID and tell the user where in the machine the fault has
occurred.
