4.2 PC commands

The command to be effected from the PC is the on-demand command only. This command can be used only when the system configuration is 1:1. In this on-demand command, the content of the data register specified at the PC side is transmitted to the computer side from the PC side. The maximum number of points of the data register that can be transmitted as follows.

PC series	Max. number of points
FX0N	13 words
FX , FX2C	64 words
