Omron C500-LK009-V1 ユーザーズマニュアル

Switch settings for the following System are given below for level 0. The set-
tings for all PC Link Units in level 1 would be the same, except for the level
setting (pins 3 and 4 on the back-panel DIP switches). These are the normal
settings, but not the only ones possible. The System is multilevel with two
Subsystems, contains eight PC Link Units in each Subsystem, and combines
C2000H, C500, and C200H PCs.
