I/O Allocation to CompoBus/S Slaves

Note
The CompoBus/S input area (IR 020 to IR 027) and CompoBus/S output area
(IR 030 to IR 037) are allocated for the CompoBus/S Terminal's I/O. The fol-
lowing table shows the I/O allocation of the CompoBus/S Terminal (IN0 to
IN15 and OUT0 to OUT15.)

1. IN0 to IN15 are node numbers of Input Terminals and OUT0 to OUT15 are
node numbers of Output Terminals.
2. When the maximum number of CompoBus/S nodes is set to 16, IN8 to
IN15 and OUT8 to OUT15 can be used as work bits.
3. CompoBus/S Terminals with 8 points or less are allocated I/O bits in byte
units beginning from bit 00 or bit 08.
4. Only even addresses can be specified for 16-point CompoBus/S Termi-
nals.
