8. PERSONAL COMPUTER
In the Motionpack-ll0 system, the input/output of various data can be made by means of an a
external personal computer. The personal computer can be connected to motion modules
through the CRT control station or can be directly connected to motion modules. However,
the setting and the operation will be slightly different between the former and the latter.
Refer to Fig. 2.1.
