The I/O words allocated to slave over-
lap.
Correct the node addresses of the
slaves so that I/O area words do not
overlap.
Set the node addresses of the slaves
so that I/O area words do not overlap.
The I/O words allocated to the slave
exceed the valid range.
Correct the node addresses of the
slaves so that the I/O area words do
not exceed the valid range.
Set the node addresses of the slaves
so that the I/O area words do not
exceed the valid range. Or, use the
slaves with user allocations.
The I/O size of the slave exceeds 200
bytes for outputs or 200 bytes for
inputs.
Use a slave with 200 output bytes or
less and 200 input bytes or less.
Use a slave with 200 output bytes or
less and 200 input bytes or less.
