<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.
• Response to the Inverter Status Read
The response to the DSR message to request the Inverter status in register 002C Hex consists of the
following items.
Set data: <a> + [03] + <I> + (W (1N + 1), 2) + <c>
<a., [03], <c>
The address data, constant data, and check code data are the same as the above.
<l>
The length is set in the length box. Insert the length by using the Insert icon. The length is the number of
bytes of the succeeding data (W(1N + 1), 2). The length is automatically set by the CX-Protocol.
(W(1N + 1), 2)
The Inverter's actual data is to be sent. This example selects Variable and Read R() and sets the oper-
and. Set Data to 1N + 1 because the RUN command data uses four bytes each from D + 3, D + 6, and D +
9.
Set Edit Length to 0N + 2 so that it will be set to two bytes.
Inverter status data (Set with variable)
Number of bytes of attached data (set with <l>)
Function code (Write 10)
Slave address (Set with <a>)
CRC-16 check (Set with <c>)
