When a communications instruction
is executed with automatic port allo-
cation, the corresponding flag is
turned ON for just one cycle after
communications have been com-
pleted. Bits 00 to 07 correspond to
ports 0 to 7.
Use the Used Communications Port
Number stored in A218 to determine
which flag to access.
Note: These flags are not effective
When a communications instruction
was executed with automatic port
allocation and an error occurred, the
corresponding flag is turned ON for
just one cycle. Bits 00 to 07 corre-
spond to ports 0 to 7.
Use the Used Communications Port
Number stored in A218 to determine
which flag to access. The cause of
the error can be determined with the
Communications Port Completion
Codes stored in A203 to A210.
Note: These flags are not effective
When a communications instruction
was executed with automatic port
allocation, the response (comple-
tion) code for the communications
instruction is automatically stored in
the word with the PLC memory
address specified in these words.
Note: The PLC memory address
When a communications instruction
is executed with automatic port allo-
cation, the allocated communica-
tions port number is stored in this
word. Values 0000 to 0007 hex cor-
respond to ports 0 to 7.
ON when an error occurred during
execution of a network instruction
(SEND, RECV, CMND, or PMCR).
Bits 00 to 07 correspond to commu-
nications ports 0 to 7.
(All of these flags are turned OFF at
the start of program execution and
the flag for a given port is turned
OFF when a network instruction with
that port number is executed.)
(When the simple backup operation
is used to performed a write or com-
pare operation for a Memory Card, a
communications port will be auto-
matically allocated, and the corre-
sponding Flag will be turned OF if an
error occurs.)

communications instruction is
executed. Delay accessing
them for at least one cycle.
