The Analog Output 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 Output Unit depend on the setting of the unit num-
ber setting switch on the front panel of the Unit. Those ten words are then re-
served as an I/O refresh data area, and the bits that comprise that area are re-
freshed with every I/O refresh cycle by the PC.
At the I/O refresh by
the PC, outputs (PC to
Unit) and inputs (Unit to
PC) are executed in or-
der with every cycle.
Note 1. The unit number that is set for an Analog Output Unit must not be used for
any other Special I/O Unit. If overlapping numbers are set, 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.
