Prevention
A slave that is in the scan list does not
exist.
•
The master and slaves have differ-
ent communications settings.
•
Communications cable lengths
(trunk line and branch lines) are
unsuitable.
•
A communications cable is discon-
nected or loose.
•
The terminating resistance is some-
where other than the ends of the
trunk line.
•
Noise
•
Correct the settings so that the
master and slaves use the same
baud rate.
•
Adjust the communications cables
of the trunk and branch lines to suit-
able lengths.
•
Connect the communications cable
securely. If the communications
cable is broken, replace it.
•
Connect terminating resistance only
to the ends of the trunk line.
•
Implement noise countermeasures.
•
Set the master and slaves to the
same baud rate.
•
Install suitable lengths of communi-
cations cables for the trunk and
branch lines.
•
Connect the communications cable
securely. Check to see if the com-
munications cable is broken.
•
Connect terminating resistance only
to the ends of the trunk line.
•
Implement noise countermeasures.
The node address of the local Unit,
which is the master, is registered in
the scan list.
Do not register the node address of
the local Unit in the scan list.
Do not register the node address of
the local Unit in the scan list.
If the system is set to check the ven-
dor in the detailed verification set-
tings, the vendor of the slave does not
match the registration in the scan list.
Correct the scan list if the slave is cor-
rect. If the slave is incorrect, replace it
with the correct slave.
Make sure that the information in the
scan list matches the information of
the slaves that are actually con-
nected.
If the connection path is set in the
detailed verification settings, then set-
ting the connection path that is set in
the scan list failed.
The size of the slave I/O data does
not match the registration in the scan
list.
If the device type is set in the detailed
verification settings, then setting the
device type that is set in the scan list
failed.
If the product code is set in the
detailed verification settings, then set-
ting the product code that is set in the
scan list failed.
The device does not support the I/O
service specified in the scan list.
