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 DSR message in details.
•
DSR Message Requesting that the RUN Command and Frequency Reference be Written
The DSR message to write data to two registers from register 0001 Hex (the RUN command) consists
of the following items.
CRC-16 check (Set with <c>)
Set with variables
Next register data
Start register data
Number of bytes of attached data (set with <l>)
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] + <I> + (R (3N + 3), 4) + <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 DSR message.
Use
Set Constant
and set the constants in Hex.
<I>
The length is set in the length box. Insert the length by using the
Insert
icon. The length is the num-
ber of bytes of the succeeding data (R(3N + 3), 4). The length is automatically set by the CX-Proto-
col.
(R(3N+3), 4)
The Inverter’s actual data to be sent. This example selects
Variable
and
Read R()
and sets the
operand. Set
Data
to 3N + 3 because the RUN command data uses four bytes each from S + 3, S +
6, and S + 9.
Set
Edit Length
to 0N + 4 so that it will be set to four bytes.
<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 operated. Mark all the items if the Protocol
Support Tool is used. The check code is automatically set by the CX-Protocol.
