C
C through C+2 must be within the same data area and must be within the val-
ues specified below. To be able to use RECV(98), the system must have a
Controller Link Unit mounted.
When the execution condition is OFF, RECV(98) is not executed. When the
execution condition is ON, RECV(98) transfers data beginning at S from a
node on the Controller Link System to words beginning at D. The control
words, beginning with C, provide the number of words to be received, the
source node, and other transfer parameters.
Control Words
RECV(98) receives "m" words beginning with S (the beginning word for data
transmission at the destination node, M) to the words from D (the beginning
word for data reception at the source node) onwards.
S: Destination node beginning send word
D: Source node beginning receive word

C: Source node first control data word

This setting is enabled only when "Destination network address specified" is set in word C.
When specifying the destination network address, set all the nodes in the routing tables. For
details on the routing tables, refer to the section on network interconnections in the Controller
Link Unit Operation Manual (W309).
