The High–Speed Serial Bus is a serial interface to enable high–speed data
transfer between a PC installed on the operator’s panel and the CNC
control section.
If a dedicated interface board is installed in a commercially available IBM
PC or compatible, it becomes possible to connect the PC to the CNC
control section via the High–Speed Serial Bus. This bus has the following
features.
A large amount of data can be transferred between the PC and the CNC
control section.
A high–reliability optical fiber cable is used for connection between
the PC and the CNC control section.
Machine tool builders can select a PC that meets the requirements on
the machine system side.
