I/O Bit Addresses
Units 8 Input Points (CP1W-8ED/CPM1A-8ED)
Eight input bits are allocated in one word (bits 00 to 07 in CIO m).
Only one word (8 bits) is allocated to an 8-input Expansion Input Unit. No out-
put words are allocated. Input bits 08 to 15 are always cleared by the system
and cannot be used as work bits.

Sixteen output bits in two words are allocated in two words (bits 00 to 07 in
CIO n and bits 00 to 07 in CIO n+1).
Two words (16 bits) are allocated to a 16-output Expansion Output Unit. No
input words are allocated. Output bits 08 to 15 can be used as work bits.

Twelve input bits are allocated in one word (bits 00 to 11 in CIO m). Eight out-
put bits are allocated in one word (bits 00 to 07 in CIO n).
One input word (12 bits) and one output word (8 bits) are allocated for a 20-
point Expansion I/O Unit.
Input bits 12 to 15 are always cleared by the system and cannot be used as
work bits. Output bits 08 to 15, however, can be used as work bits.

Thirty-two output bits are allocated in four words (bits 00 to 07 in CIO n, bits
00 to 07 in CIO n+1, bits 00 to 07 in CIO n+2 and bits 00 to 07 in CIO n+3).
Four words (32 bits) are allocated to a 32-output Expansion Output Unit. No
input words are allocated. Output bits 08 to 15 can be used as work bits.
