cuting the SEND(090), RECV(098), and CMND(490) instructions for the
internal logic ports (8 ports max.). Up to eight Controller Link Units can be
connected to a single CPU Unit with unit version 1.2 or later. Perform
exclusive control of the ports using the ladder program when using the
SEND(090), RECV(098), and CMND(490) instructions to perform mes-
sage servicing on multiple networks (Units).
(Unit) when using unit version 1.2 or later. Data of 20,000 words is divided
and refreshed across three CPU Unit cycles. Make sure that the response
time has been considered in the system design. (Data is synchronous for
each node when data is refreshed in the CPU Unit, in the same way as for
earlier versions. If the number of data link words is 12,000 words or less,
the response with earlier unit versions (pre-Ver. 1.2) is exactly the same.)

used. For an example of calculating current consumption, refer to
