Indirect Designation of
Beginning Words
174
Introduction
CVM1, CV-series, and CS/CJ-series PLCs have a larger area than C200HX/
HG/HE PLCs, so the beginning words for sending and receiving at destination
nodes cannot always be directly specified by means of SEND and RECV
operands. Moreover, depending on circumstances, it may be desirable to
change the beginning word at destination nodes.
In such cases, set the “Direct/Indirect” control data designation to “1” (Indi-
rect), and specify the beginning words for sending and receiving as described
below.
SEND
The beginning receive word is determined by the contents of the destination
node’s D and D+1 words.
RECV
The beginning send word is determined by the contents of the destination
node’s S and S+1 words.
cessing is performed automatically once the number of retries has been
set, so be sure to specify a number other than “0” for the number of retries.
