(2) Precautions
(a) Type setting
The type set in the I/O Assignment tab must be the same as that of the connected module. Setting a different
type may result as follows.
Connected modules
• Input module
• Output module
Intelligent function module
Any module
Other combinations
For intelligent function modules, the number of I/O points must be the same.
(b) I/O points of modules
The number of I/O points for each module selected in the I/O Assignment tab is set in priority to those of
connected modules.
• If the preset number of I/O points is less than those of connected I/O modules, the available points for the
connected I/O module are decreased.
If the number of I/O points is set to 16 points in the I/O Assignment tab to the module where a 32-point
Ex.
Ex.
input module is connected, the second half 16 points of the 32-point input module are invalid.
• If the preset number of I/O points exceeds those of connected I/O modules, the exceeded number of
points will not be used.
Set the last I/O number within the I/O point range. Failure to do so causes "SP. UNIT LAY ERR.".
(c) Start XY setting
Note that, in the following two cases, the start XY setting may be duplicated. ("SP.UNIT.LAY.ERR." occurs if the
start X/Y is duplicated.)
• Start XY values are not in the correct order.
• Modules with and without the start XY setting (automatically assigned module) are mixed.
Type specified in the I/O
Assignment tab

"SP.UNIT.LAY.ERR." occurs.

Error does not occur but incorrect operation may be caused. Or
