Network Instructions Section 3-25
Operand Specifications
Description 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.
