Description
(7) Refer to Automatic Allocation of Communications Ports on page 851 for
details on using automatic allocation of the communications port number
(logical port).
(8) When the destination node number is set to FF (broadcast transmission),
there will be no response even if bits 12 to 15 are set to 0.

SEND(090) transfers the data beginning at word S to addresses beginning at
D in the designated device through the PLC's CPU Bus or over a network.
The number of words to be transmitted is specified in C.

If the destination node number is set to FF, the data will be broadcast to all of
the nodes in the designated network. This is known as a broadcast transmis-
sion.
If a response is requested (bits 12 to 15 of C+3 set to 0) but a response has
not been received within the response monitoring time, the data will be
retransmitted up to 15 times (retries set in bits 0 to 3 of C+3). There will be no
response or retries for broadcast transmissions.
SEND(090) can be used to transmit data to a particular serial port in the des-
tination device as well as the device itself.
Data can be transmitted to a host computer connected to the PLC's serial port
(when set to host link mode) as well as a PLC or computer connected through
a Controller Link or Ethernet network.
