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.
With CS/CJ-series PLCs, communications ports 0 to 7 are also used for exe-
cuting the PCMR(260) (PROTOCOL MACRO) instruction, so these flags are
used in common for SEND(090), RECV(098), CMND(490), and PCMR(260).
While PCMR(260) is being executed, SEND(090), RECV(098), and
CMND(490) cannot be executed at the same communications port.

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.)
