Troubleshooting Section 8-1
Network Relay Errors For network relay errors using SEND(90) or RECV(98), check the path of the
command using the routing tables and the nature of the error using the
response code to eliminate the cause of the error.
For network relay errors using CMND(490), the location of the relay error is
recorded in the second and third words of the response, as shown below.
Network error address: 00 to 7F (0 to 127)
Node error address
SYSMAC LINK: 01 to 3E (1 to 62)
Controller Link: 01 to 20 (1 to 32)
26: Command error 01 The specified area is not protected.
This response code will be returned if
an attempt is made to clear protection
on an area that is not protected. The program area is not protected, so it is
not necessary to clear protection.
02 An incorrect password has been speci-
fied. Specify a password that is registered.
04 The specified area is protected. Execute the command again after the PRO-
GRAM AREA PROTECT CLEAR com-
mand.
05 The service is being executed. Execute the command again after the ser-
vice has been completed or aborted.
06 The service is not being executed. Execute the service if necessary.
07 Service cannot be executed from local
node because the local node is not part
of the data link. Execute the service from a node that is part
of the data link.
08 The communications cycle time in the
data link table is too short. (The LNK
indicator will be flashing rapidly.) Either use the automatic setting or increase
the setting manually.
09 Service cannot be executed because
the necessary settings have not been
made in the command data. Check the command format and make the
necessary settings.
0A The specified action or transition num-
ber has already been registered. Execute the command again using an
action or transition number that has not
been registered.
0B Cannot clear error because the cause
of the error still exists. Eliminate the cause of the error and exe-
cute the ERROR CLEAR command.
30: Access right error 01 The access right is held by another
device. Execute the command again after the
access right has been released.
(The command can be executed after the
ACCESS RIGHT FORCED ACQUIRE or
ACCESS RIGHT RELEASE command is
completed. Releasing the access right
might affect processes in progress at the
node that held the access right.)
