[Function]
• As many data words as specified in bytes will be transferred from the area specified by a
transmission data storage address to the remote node having a specified node number as a
transparent message having the TCD number specified by a transmission message TCD.
• When the transmission destination node number is set to 255, a one-to-N transmission takes
place.
• When the data word count is set to 0, a transmission takes place with no data added.
• For a transmission message TCD, you cannot specify the following TCD numbers that are
used by the transparent message-unique support feature (specified task control/specified
subroutine control).
<TCD numbers that cannot be specified>
For LQE500: 10000, 10001, 10200, 10201
For LQE502: 1000, 1001, 1200, 1201
FL.NET module-unique feature
When a TCD number between 0 and 999 is specified, the transmission data is sent as data in
little-endian format. If the transmission word count is expressed by an odd number of
bytes, the transmission data is converted into little-endian format with the 1-byte data "0x00"
added. If the specified TCD number is other than the above, the transmission data is sent as
is.
Data conversion effected when the specified TCD number is between 0 and 999
Example: When 4-byte data is received
Data n
Data n + 1
Byte-swapped on an individual word basis and then transmitted.
Data n + 1
Data n
5-94
Data n + 2
Data n + 3
Data n + 3
Data n + 2
