NETWORK SEND Instruction - SEND(90)
The SEND(90) instruction allows a PLC to write data to the memory of a
device located at a node on a local or remote network.
Format
The format of the SEND(90) instruction is as follows:
Control Data
Set the destination node address to $FF to broadcast the data to all nodes in
the designated network or to $00 to send to a destination within the node of
the PLC executing the send.
Note
Transmissions cannot be sent to the PLC executing the send.

1.
Number of Words
Set the total number of words to be transferred.
2.
Destination Network Address
Set the destination network address to 00 if the destination network ad-
dress is a local network. If more than one SYSMAC LINK Unit, Controller
Link Unit, or Ethernet Unit is mounted to the PLC, the network of the Unit
with the smallest unit address will be considered to be the local network.
3.
Destination Node Address
Set the destination node address to FF for broadcasting within the local
network. Set to 00 (and set the network address to 00) for transmission to
a device at the local node.
4.
Destination Unit Address
Set the destination unit to 00 if the destination is a PLC. If the destination
is a user’s application on a computer (NSB), set the destination unit ad-
dress to 01 (user application 1).
