Recv Message Detail Settings
1. With the left button of the mouse, click on Receive Message List. Then click on a blank space with the
right button of the mouse.
2. Select Create Receive Message.
The following table will appear. Set the Receive message in the table.
Message
Header <h> Terminator <t>
Input response
Read response
Message
The label (name) of the response. Input an appropriate, easy-to-distinguish name.
Set the label in the Recv message box in the table shown under Creating a Step.
Header <h> and Terminator <t>
Set the header and terminator.
No header or terminator is used for communications with the 3G3RV. Therefore, set both to None.
Check Code <c>
Set the check code.
The CRC-16 check code is used for communications with the 3G3RV. Select the CRC-16 check code and set
the initial value to 65535.
Select Reverse for the conversion method. Then select BIN as the data type.
Length <l>
Set the length of the data.
All communications with the 3G3RV are performed in byte units. Select 1 Byte and BIN. Select No for read-
ing data because there is no data to be read.
Address <a>
Set the addresses of the Slaves.
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 MSB. 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.
