Serial Communications Instructions
Section 3-24
Communications Responses
Communications Port Error
Flag
A21900 to
A21907
ON when an error occurs in network
communications.
Bits 00 to 07 correspond to logical ports
0 to 7, respectively.
Flag status will be maintained until the
next network communications start.
The flag will turn OFF when communi-
cations start again even if an error
occurred for the last execution.
Communications Port Com-
pletion Codes
A203 to A210 Contains the completion code stored
when network communications are per-
formed.
Words A203 to A210 correspond to log-
ical ports 0 to 7, respectively.
The completion code will be 00 while
the communications instruction is being
executed. The new response code will
be stored when execution has been
completed.
The contents of these words is cleared
when operation is started.
Code
Contents
1106 (hex)
No corresponding program number
Specified Send/Receive Sequence No. that has not
been registered.
Modify the Send/Receive Sequence No. or add the
number using the CX-Programmer.
2201 (hex)
Not operable due to protocol execution
Since one protocol macro has already been executed,
no further execution is accepted.
Add NC condition to program for the Protocol Macro
Execution Flag.
2202 (hex)
Not operable due to stoppage
Since the protocol is being switched, no further execu-
tion is accepted.
Add NC condition to program for the Serial Setting
Change Flag.
2401 (hex)
No registration table
An error has occurred in the protocol macro data or
data is being transmitted.
Transmit the protocol macro data using the CX-Pro-
grammer.
