I/O Area and I/O Allocations

I/O Area and I/O Allocations
Input Bits: CIO 0.00 to CIO 16.15 (17 words)
Output Bits: CIO 100.00 to CIO 116.15 (17 words)
The starting words for inputs and outputs are predetermined for CP1H 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. CPM1A Expan-
sion Units and CPM1A Expansion I/O Units are automatically allocated input
bits in words starting from CIO 2 and output bits in words starting from
CIO 102.
Note
CJ-series Basic Units cannot be connected to a CP1H PLCs.
Bits in the I/O Area can be force-set/reset from the CX-Programmer.
The I/O Area will be cleared at the following times:
(1) When the operating mode is changed between PROGRAM mode and
RUN or MONITOR mode
(2) When the power is cycled
(3) When I/O memory is cleared from the CX-Programmer
(4) When operation fails due to a fatal error other than one created by exe-
cuting a FALS(007) instruction (Memory will be retained if operation fails
due to execution of a FALS(007) instruction.)
4-2-1
Overview
CIO 0 and CIO 1 are allocated to the built-in inputs and CIO 100 and CIO 101
are allocated to the built-in outputs on the CPU Unit.
For CPM1A Expansion Units and Expansion I/O Units, inputs are allocated in
the order that the Units are connected starting from CIO 2 in the Input Area
and from CIO 102 in the Output Area. (See note.)
A total of up to seven CPM1A Expansion Units and Expansion I/O Units can
be connected. The total number of input words and output words must be 17
or less. A fatal error (Too Many I/O Points) will occur if this limit is exceeded,
and operation will stop.
CP1H CPU Unit
Built-in inputs: CIO 0 and
CIO 1 are allocated.
Built-in outputs: CIO 100 and
CIO 101 are allocated.
Expandable up to a total of seven CPM1A
Expansion I/O Units and Expansion Units.
Expansion I/O Unit and Expansion Unit inputs:
Words are allocated starting from CIO 2.
Expansion I/O Unit and Expansion Unit outputs:
Words are allocated starting from CIO 102.
