Troubleshooting Error Messages in CX-Net Data Link Table Check Section 9-4
The XX symbol refers to the corresponding node address. The two
asterisks (**) refer to the corresponding area type, address, and number of
words.
Node XX Dest Over-
flow
Warning: Overflow occurred The number of receive words at the destination node is
larger than the number of send words at the source node.
Change the number of send words or number of receive
words if the allocations are not intended. If the allocations
are intended, the data link tables can be transmitted without
making any changes.
Warning: Block outside bounds of
Link from node **. Enter value in
range ** to **
The number of receive words at the destination node is
smaller than the number of send words at the source node.
Change the number of send words or number of receive
words if the allocations are not intended. If the allocations
are intended, the data link tables can be transmitted without
making any changes.
Node XX Node size Warning: The total node send
and receive size of ** exceeds
12000
The total number of send and receive words exceeds
12,000. Controller Link Units with unit version 1.2 or later are
required for data links with 20,000 send and receive words.
For pre-Ver. 1.2 Controller Link Units, reduce the number of
send and receive words.
Total Node send size of **
exceeds max 20000
The total number of send and receive words exceeds
20,000. Reduce the number of send and receive words to
within the maximum.
Total Node send size of **
exceeds max 8000
The total number of send and receive words exceeds 8,000.
Reduce the number of send and receive words to within the
maximum.
Total Node send size of **
exceeds max 62000
The total number of send and receive words exceeds
62,000. Reduce the number of send and receive words to
within the maximum. (The 62,000 maximum can be
exceeded by personal computer boards only.)
Total Node send size is 0 The number of allocated words for node ** in node No. xx is
0. Change the number of words or delete the node.
Total Node send size of **
exceeds max 1000
The total number of send words for node XX exceeds 1,000.
Set the number of send words to 1,000 words or less.
Node XX Area Overlap
Node XX Area Conflict
Warning: Duplicated area exists
in Area 1 and status area
The same words have been allocated for both the Data Link
Area 1 and status area. If the duplication is not intended,
change the settings for either area. If the duplication is
intended, the data link tables can be transmitted without
making any changes.
Warning: Duplicated area exists
in Area 2 and status area
The same words have been allocated for both the Data Link
Area 2 and status area. If the duplication is not intended,
change the settings for either area. If the duplication is
intended, the data link tables can be transmitted without
making any changes.
Warning: Link memory areas 1
and 2 are both set to - [Area]
The same area has been set for both Data Link Area 1 and
2. The same area can be set if using Controller Link Units
with unit Ver. 1.2 or later. If a pre-Ver. 1.2 Controller Link Unit
is being used, set a different area each for Area 1 and Area
2. (This message is displayed for CS/CJ-series CPU Units
only.)
Link memory areas 1 and 2 are
both set to [Area]
The same area has been set for both Data Link Area 1 and
2. Set a different area each for Area 1 and Area 2. (This mes-
sage is displayed for CS/CJ-series CPU Units only.)
Link memory areas 1 and 2 are
both set to [Area]
The same address has been set for the Data Link Area and
the area in which both Area 1 and Area 2 are set. Reset the
addresses so that no duplication occurs. (This message is
displayed for CS/CJ-series CPU Units only.)
