Unit Number Setting
The C200H and C200HS PCs can each use a maximum of 10 Special I/O
Units and their unit numbers set within a range of 0 to 9.
The C200HX, C200HG, and C200HE PCs can each use a maximum of 16
Special I/O Units, the unit numbers of which are set within ranges of 0 to 9
and A to F.
DM
A block of 100 words within a range of DM 1000 to DM 2599 is allocated to the
Special I/O Unit.
The words allocated to the Special I/O Unit are within the following range.
Word m to word m+99 (m = 1000 + 100 x Unit No. 0 to 15)
IR Bit
A block of 10 words within a range of IR 100 to IR 199 or IR 400 to IR 459 is
allocated to the Special I/O Unit.
The words allocated to the Special I/O Unit are within the following range.
Word n to n+9 (n = (100 + 10 x Unit No. 0 to 9) or (400 + 10 x (Unit No. – 10)
(Unit No. 10 to 15))
IR words n and n+1 are used for outputs from the PC to the Special I/O Unit
and IR words n+2 to n+9 are used for inputs from the Special I/O Unit to the
PC.
After setting the unit number, check the DM and IR areas allocated to the
High-speed Counter Unit and write programs.
