The Analog Input Units are allocated ten words each from the portion of the IR
area (IR 100 to IR 199) that is reserved for Special I/O Units. The words that are
allocated a particular Analog Input Unit depend on the setting of the unit number
on the front panel of the Unit. Those ten words are then reserved as an I/O re-
fresh data area, and the bits that comprise that area are refreshed with every I/O
refresh cycle by the PC.
IR 100 to 109
IR 110 to 119
IR 120 to 129
At the I/O refresh by the
IR 130 to 139 PC, outputs (PC to Unit)
and inputs (Unit to PC)
IR 140 to 149
are refreshed in order
with every cycle.
IR 150 to 159
IR 160 to 169
IR 170 to 179
IR 180 to 189
IR 190 to 199
IR 400 to 409
IR 410 to 419
IR 420 to 429
IR 430 to 439
IR 440 to 449
IR 450 to 459
Note 1. The unit number that is set for an Analog Input Unit must not be used for any
other Special I/O Unit. If the same unit number is set more than once, an I/O
UNIT OVER error will be generated and operation will be stopped.
2. The unit number can be set to between A and F Hex (10 to 15 decimal) only
when a C200H-AD002 with a lot number jj16 or later (January 1996 or
later) is used with a C200HG-CPU53/CPU63 or C200HX-CPU54/CPU64
CPU Unit.

The OUT and IN refreshes are as seen
from the PC.
