CIO Area addresses run from words CIO 0000 through CIO 2555 and bits
CIO 000000 through CIO 255515 and are divided into eight data areas. Five
of these data areas are used to control I/O points and Special Units, and
three data areas are used to manipulate and store data internally. The CIO
Area is accessible either by bit or by word. No prefix is required when input-
ting data area addresses; the CIO prefix is used only for clarity in descrip-
tions.
The name, range, and function of each data area within the CIO Area are sum-
marized in the following table. PC memory addresses are in parentheses.

Function
Allocated to I/O in the System and used to
control I/O points. Bits not used to control
I/O points can be used as work bits. The PC
Setup can be used to control allocations. S t b d t t l ll
Once I/O table has been registered, input
bits are dis layed on CVSS/SSS with an I bits are displayed on CVSS/SSS with an I;
output bits, with a Q.
These bits are used in the program to
manipulate or to temporarily store data.
These bits are used for remote I/O points in
the SYSMAC BUS/2 Remote I/O System
unless the default allocations are changed in
the PC Setup.
Bits not used to control I/O points can be
used as work bits.
These bits are used for SYSMAC NET Link
and SYSMAC LINK Systems. Bits not used
for data links can be used as work bits.
These bits can be set as holding bits via PC
Setup.
Used to store data and to retain the data
values when the power is turned off.
Used to store the operating status of CPU
Bus Units. Bits not used by CPU Bus Units
can be used as work bits. These bits can be
set as holding bits via the PC Setup.
These bits are used in CompoBus/D
networks. Bits not used for CompoBus/D
can be used as work bits.
