Programs incorporating the SEND(090), RECV(098), and CMND(490)
instructions are generally created using the Communications Port Enabled
Flag and the Communications Port Error Flag as input conditions. CS/CJ-
series CPU Units have eight communications ports. Only one instruction can
be executed at any given port at one time, however, so the program must not
overlap the use of any of the ports. A program example is provided below.

Ethernet Unit
There are eight communications ports, so up to eight
communications instructions can be executed at a time. The
number of messages that can be sent or received with a
single CPU Bus Unit ser-vice, though, is not more than two
each for the CPU Unit to the Ethernet Unit and for the
Ethernet Unit to the CPU Unit.
