7-1-7 Allocating I/O Data in the Master
Allocation method
Allocated area in
Master
Fixed allocations 1.

Note Settings from the Master are
User allocations 1.

3.
Note Supported
I/O is allocated in the Master using the methods shown in the following table.
Select the appropriate method depending on whether the allocated area in
the Master is fixed or user-defined, and whether the allocated I/O data is the
default I/O, a selected combination of data, or user-defined data.
Allocated I/O data
Default I/O data allocation
Using Configurator to select I/O data
(patterns) by editing the Slave's de-
vice parameters (fixed I/O data com-
binations)
supported by CJ/CS-series
DeviceNet Units only.
Default I/O data allocation
Using Configurator to select I/O data
(patterns) by editing the Slave's de-
vice parameters (fixed I/O data com-
binations)
Using Configurator to select I/O data
for each connection by editing the
Master's device parameters and al-
locating each data to user-defined
addresses (user-defined I/O data
combinations)
by CJ/CS-series
DeviceNet Units only.
Note For details on the data allocation patterns and methods, refer to 7-4-2 I/O
Data Allocation Methods.
I/O data that can be allocated in the Master
Allocates only analog/temperature input values for 4
points.
The following 11 types of I/O data can be allocated by
selecting from the pull-down menu for the Slave's default
connection path.
• Analog Data 1 or Temperature Data 1
• Analog Data 2 or Temperature Data 2
• Generic Status Flags
• Top/Valley Detection Timing Flags
• Analog Status Flags
• Analog Data 1 + Analog Data 2 or Temperature Data 1
+ Temperature Data 2
• Top/Valley Detection Timing Flags + Generic Status
Flags
• Analog Status Flags + Generic Status Flags (5 input
bytes)
• Analog Data 1 or Temperature Data 1 + Top/Valley
Detection Timing Flags
• Analog Data 1 or Temperature Data 1 + Top/Valley
Detection Timing Flags + Generic Status Flags
• Hold Flags
(Same as fixed allocations.)
(Same as fixed allocations.)
The following 11 types of I/O data can be allocated by
selecting up to two types from the pull-down menu for
the Master's connection path.

• Generic Status Flags
• Top/Valley Detection Timing Flags
• Analog Status Flags
• Analog Data 1 + Analog Data 2
• Top/Valley Detection Timing Flags + Generic Status
Flags
• Analog Status Flags + Generic Status Flags
• Analog Data 1 or Temperature Data 1 + Top/Valley
Detection Timing Flags
• Analog Data 1 or Temperature Data 1 + Top/Valley
Detection Timing Flags + Generic Status Flags
• Hold Flags
