Overview of CompoBus/S Communications Model Section 3-1
3-1-3 Using CompoBus/S Remote I/O Communications: Example
The following example is for monitoring the ON/OFF output status of Fiber
Amplifier Unit number 1, with DIP switch pin 1 OFF, E3X-SRT21 CompoBus/S
node address 00, and CompoBus/S Master Unit Special I/O Unit number 0.
The IN Area starts at CIO 2000 and runs through the rightmost byte (bits 00 to
07) of CIO 2004 (word n + 4) in the IN Area. The eight bits of the Communica-
tion Unit slave 00 are allocated bits 00 to 07 of CIO 2004.
