IR/CIO Area Allocations
Section 3-1
3-1 IR/CIO Area Allocations
3-1-1 Overview
Each ASCII Unit is allocated 10 words in the Special I/O Unit Areas of the
CPU Unit’s IR or CIO Area. The words that are allocated depend on the Unit
No. set on the rotary switch on the front panel of the ASCII Unit. The contents
of the allocated 10 words is exchanged automatically between the CPU Unit
and the ASCII Unit every time the CPU Unit refreshes I/O.
Data Exchange for the C200HX/HG/HE, C200H, C200HS
Note For CPU Units C200HG-CPU53-E/63-E/53-ZE/63-ZE and C200HX
-CPU54-E/64-E/54-ZE/64-ZE/65-ZE/85-ZE, IR 400 to IR 459 are also allo-
cated (maximum of 16 Special I/O Units).
