4-2-1 Allocation Area Sizes (IN Data Size and OUT Data Size)
The size of allocated data in each of the IN and OUT Areas is shown in the fol-
lowing table.
Note (1) When the master is a CS/CJ-series DeviceNet Unit, the IN Area can be
divided into two areas (IN Area 1 and IN Area 2). Any allocation data from
the list of parameters can be allocated in each area.
(2) The actual size of the allocated area depends on the size of allocation
data selected.
(3) The default allocation data size is two bytes.
When the allocation data size is two bytes, the monitor and setting data will be
displayed in the range FFFF hex to 0000 hex. Data will be fixed at 7FFF hex
or 8000 hex if the data exceeds the range that can be displayed. For example,
−
32769 would be displayed as 8000 hex.
The following data sizes are fixed, however.
• General status: 2 bytes (fixed)
• K3HB-DRT status: 4 bytes (fixed)
• K3HB-DRT Output Enable Bits and operation commands: 2 bytes (fixed)
Note Refer to 4-2-5 Input Data on page 6-5 for details on General Status. Refer to
4-2-6 Output Data on page 6-5 for details on Output Enable Bits and opera-
tion commands.
4-2-2 Allocation Parameters
The parameters that can be allocated are shown below. These parameters
can be broadly classified as K3HB-DRT status bits/operation commands, and
K3HB-DRT operation data and setting data.
1. K3HB-DRT Status Bits/Operation Commands
The status bits and operation commands for the K3HB-DRT Digital Indica-
tor are shown in the following table.
For status details, refer to the
CompoWay/F SECTION 2 List of Settings .
Note (1) When items that are write-only are allocated in the IN Area, they are al-
ways set to 0.
(2) When items that are read-only are allocated in the OUT Area, they are
allocated words in memory but operate the same as if they had not been
allocated.
