I/O Area and I/O Allocations

I/O Area and I/O Allocations
Input Bits:
CIO 0.00 to CIO 99.15 (100 words)
Output Bits:
CIO 100.00 to CIO 199.15 (100 words)
The starting words for inputs and outputs are predetermined for CP1L CPU
Unit. Input bits in CIO 0 and CIO 1 and output bits in CIO 100 and CIO 101
are automatically allocated to the built-in I/O on the CPU Unit. CP-series
Expansion Units and CP-series Expansion I/O Units are automatically allo-
cated input bits in words starting from CIO 2 and output bits in words starting
from CIO 102.
• Allocated Words and Number of Expansion Units and Expansion I/O
Units
For example, with a CPU Unit with 40 I/O points, the input bits in CIO 0 and
CIO 1 and the outputs bits in CIO 100 and CIO 101 would be allocated to the
built-in I/O of the CPU Unit. Input bits in CIO 2 and higher and outputs bits in
CIO 102 and higher would be automatically allocated in order to any Expan-
sion Units or Expansion I/O Units connected to the CPU Unit.
When the power to the CPU Unit is turned ON, the CPU Unit checks for any
Expansion Units and Expansion I/O Units connected to it and automatically
allocates I/O bits. If the order in which the Units are connected is changed, the
the bits used in the ladder program will no longer match the bits allocated to
the actual Units. Always review the ladder program whenever changing the
order in which Units are connected.
