Slave Unit Allocations for Communications Mode Number 8

When using communications mode 8, I/O ports are not used. I/O data for the CompoNet Master Unit is
assigned in software settings directly to any locations in the memory used for CJ-series Units (any
addresses in the CIO, WR, HR, or DM Area).
The software settings are made from the CX-Integrator. Slave Unit allocations are made for WORD IN,
WORD OUT, BitIN, BitOUT, Connect Flags, and Communication Error Flags for each Word or Bit Slave
Unit. To access the memory locations that were specified in the software settings from the user pro-
gram, you use user-defined variables with AT specifications to the memory used for CJ-series Units.
