Set the expected response in detail.
Response to the RUN Command and Frequency Reference
•
The response to the DSR message written consists of the following items.
1 0 0 0 0 1 0 0 0 2
Slave address (Set with <a>)
Set data
a
The Slave address is set in the address box. Insert the address with the Insert icon.
10 00
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 PST 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 fol-
lowing items.
0 3
Slave address (Set with <a>)
Set data
a 03
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 Write W () and sets the operand. Set the
data to 1N + 1 because the RUN command data uses two bytes each from D + 1, D + 2, and D + 3.
Set Edit Length to 0N + 2 so that it will be set to two bytes.
