Message Name
The label (name) of the sequence. Input an appropriate, easy-to-distinguish name.
Note Set the label in the send message box in the table shown under Creating a Step.
Header <h>
Terminator <t>
Set the header and terminator.
Note No header or terminator is used for communications with the 3G3MV. Therefore, set both to
None.
Check Code <c>
Set the check code.
Note The CRC-16 check code is used for communications with the 3G3MV. Select the CRC-16 check
code and set the default value to 65535.
Select Reverse for the conversion method. Then select BIN for date type.
Length <l>
Set the length of the data.
Note All communications with the 3G3MV are performed in byte units. Select 1 Byte and BIN. Select
No for reading data because there is no data to be read.
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 is read from the LSB. Then click on Edit Variable with the left button of the mouse.
