The execution status of the SEND(090), RECV(098), and CMND(490) instruc-
tions is always reflected by the communications flags (i.e., the Communica-
tions Port Enabled Flag and the Communications Port Error Flag). The CS/
CJ-series CPU Unit’s communications flags are allocated in the Auxiliary Area
as shown in the following table.
In CS/CJ-series PLCs, communications ports 0 to 7 are also used when exe-
cuting the PCMR(260) (PROTOCOL MACRO), TXDU(256), and RXDU(255)
instructions, so these flags are shared by SEND(090), RECV(098),
CMND(490), PCMR(260), TXDU(256), and RXDU(255).
SEND(090), RECV(098), and CMND(490) cannot be executed at a communi-
cations port if PCMR(260) TXDU(256), or RXDU(255) is being executed at
that port.

Word
Input A remains ON from start to completion of commu-
nications instruction.
Creates operand and control data in a given
area.
Executes communications instructions.
Exclusive control so execution is not simultaneous.
Use exclusive control so that no other communica-
tions instructions are started before execution of the
above communications instruction is complete.
Creates reset input. (Turns reset B ON
after execution of communications in-
struction.)
