Writing Data to the DX
Data type to be specified in a command
Data type INT16
FLOAT The data is written without
change.
INT16 The data is written without
change. *

Input value
More than 0000
–0000 to 0000
Less than –0000
*2 The data is converted as follows:
A FLOAT value with the same number of decimal places as the one specified for the channel
is converted to INT16. Other numbers are ignored.
Example: If the number of decimal places of channel 201 is "2" (For example, the range can
be set is from -200.00 to 200.00),
A FLOAT value up to two decimal places is rounded to an integer. See the example in
the following table.

On models with the PROFIBUS-DP interface (/CP1 option), the communication input
data for C01 to C24 (on the DX1000) or for C01 to C32 (on the DX2000) is reserved
for PROFIBUS-DP. Because of this, the following limitations apply to EtherNet/IP
communications.
Limitations on Explicit Messages
You cannot write values to these registers (but you can read their values).
I/O Message Limitations
You cannot use instance ID 130 or 135.
INT32
