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 3G3JV. Therefore, set both to
None.
Check Code <c>
Set the check code.
Note
The CRC-16 check code is used for communications with the 3G3JV. 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 3G3JV 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.
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.
Data
Set the DSR message in details.
