Address <a>
Set the addresses of the Slaves.
Note
In this example, the Slave addresses are set in S + 2, S + 5, and S + 8. Therefore, retrieve the data
from those locations.
The address is set in the LSB of each word. To read the byte, select
Variable Reverse
, otherwise
the data will be read from the LSB. Then click on
Edit Variable
with the left button of the mouse.
Select
Read R ()
and set
Data/Address
to the operand (3N + 2) using the number (N) of times to
repeat the step.
Set
Edit Length
to 1 byte as a default. If the default value has been changed, set it to 0N + 1.
Data
Set the expected response in details.

Response to the RUN Command and Frequency Reference
The response to the DSR message written consists of the following items.
CRC-16 check (Set with <c>)
Number of write data registers: 2
Write start register number (RUN command: 0001)
Function code (Write 10)
Slave address (Set with <a>)
Set data: <a> + [10] + [00] + [01] + [00] + [02] + <c>
<a>
The Slave address is set in the address box. Insert the address with the
Insert
icon.
[10] + [00] + [01] + [00] + [02]
Set the constants contained in the response.
Use
Set Constant
and set the constants in Hex.
<c>
The check code is set in the check code box. Insert the check code by using the
Insert
icon. All the
data including the address data before the check code is used. Mark all the items if the Protocol
Support Tool is used. The check code is automatically set by the CX-Protocol.
