7.8.10 CAN bus.
CANopen is a network communication protocol based on the CAN bus system for connecting
the CNC with remote modules and keyboards. The CAN connection supports up to 32
devices (nodes), including the central unit; more one than keyboard and several groups of
remote modules are possible.
CAN connector.
The cable shield must be connected to the connector at both ends. The connector has two
shield pins. Both pins are equivalent; the CAN shield may be connected to either one.
Characteristics of the CAN cable.
Use a specific CAN cable. The ends of all the wires and the shield must be protected by the
corresponding terminal (pin). Also use the terminals (pins) to secure the cable to the
connector.
Bus CAN with CNC (master) and RIOR nodes.
