I/O NUMBER ASSIGNMENT
(c) Model name
(d) Points
(e) Start XY
(2) Precautions for I/O assignment
(a) Slot status after I/O assignment
Empty slot
All modules
Set the mounted module model name within 16 characters.
The specified model name is not used for the CPU module. (It is used as a user's
memo.)
To change the number of occupied I/O points of each slot, select it from the
followings:
• 0 point
• 48 points
• 256 points
If the number of occupied I/O points is not designated for a slot, the one of the
actually mounted module is used.
When the I/O number of each slot is changed, you should designate the head I/O
number according to the change.
If Start XY is not designated for a slot, the I/O number continuing from the last
number of the currently designated slot is assigned.
When I/O assignment setting has been made to a slot, that setting has
precedence over the mounted module.
1) When the preset number of points is less than the number of mounted
intelligent function module points
"MODULE LAYOUT ERROR" occurs.
2) Mounted module and I/O assigned module type
The mounted module type and the set type in the I/O assignment setting must
be the same.
If not, normal operation will not be performed.
For the intelligent function module, make sure that the numbers of I/O points
are the same.
Table4.1 describes the operations performed when the mounted module type
differs from the one in the I/O assignment setting.
