Auxiliary Area
Communications Responses
Name Address Contents
Communications Port
Enabled Flag
A202.00 to
A202.07
ON when network communications are
enabled (including PMCR(260).
Bits 00 to 07 correspond to logical ports 0 to
7, respectively.
A Communications Port Enabled Flag will
turn OFF when network communications are
started and will turn ON when they are com-
pleted (regardless of whether communica-
tions end normally or in error.
Communications Port
Error Flag
A219.00 to
A219.07
ON when an error occurs in network commu-
nications.
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 communications start again
even if an error occurred for the last execu-
tion.
Communications Port
Completion Codes
A203 to A210 Contains the completion code stored when
network communications are performed.
Words A203 to A210 correspond to logical
ports 0 to 7, respectively.
The completion code will be 00 while the
communications instruction is being exe-
cuted. 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 exe-
cution 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 execution 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 trans-
mitted.
Transmit the protocol macro data using the CX-Programmer.
Others Refer to the CJ-series Communications Commands Reference Manual
(W342) for other response codes.
