4. CPU MODULE
3) The device numbers of input modules connected are as follows:
Stations 1 to 4 AX41C
Stations 5 to 6 AJ35TB-16D
Stations 7 to 8 AX40Y50C
With respect to X440 to X45F, they are simultaneously refreshed, and turned
off at all time.
Do not use X440 to X45F in the sequence program.

Output area
1) Set the device number (Y400) for b0 of the station 1 as a send data storage
device.
2) The send data storage device occupies from Y400 to Y45F.
For the present system example, since the total number of stations is odd, it
is occupied for one extra station.
3) The device numbers of output modules connected are as follows:
Stations 9 to 10 AX40Y50C
Station 11
With respect to Y400 to Y43F and Y458 to Y44F, they are simultaneously
refreshed, but are not output.
POINT
(1) Set the send and received data storage devices so that device numbers are
not overlapped.
When the received data storage device is set to B0 in the system
configuration example, it occupies B0 to B5F as the device range.
Set the send data storage device to B60 or later.
When the send data storage device is set to B60, the device range will be B60
to BBF.
(2) If a bit device is specified as the send/received data storage device, the
device number set must be a multiple of 16.
<Example>
(3) Device range used is (8 points)
When the number of stations is an odd number, extra 8 points are necessary.
