Message
The label (name) of the response. Input an appropriate, easy-to-distinguish name.
Note Set the label in theRecvmessagebox in the table shown under Creating a Step.
Header (h)
Terminator (t)
Set the header and terminator.
Note No header or terminator isused for communications withthe 3G3MV.Therefore,
set both to No.
Check Code (c)
Set the check code.
Note TheCRC-16checkcodeis used for communicationswiththe3G3MV. Selectthe
CRC-16 check code and set the initial value to 65535.
Select Reverse for the conversion method. Then select BIN.
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 Inthisexample,theSlaveaddressesaresetin S+2,S+ 5,andS+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 LSB. Then click on Execute
Address with the left button of the mouse.
