2) Setting station numbers
x The I/O numbers to be allocated to each slave station are determined by the slave station number setting.
Since each I/O number is assigned to a single slave station number, set each slave station with the slave station
number that corresponds to the I/O numbers you wish to allocate.
x To set a slave station number , turn the station number selector of the FP I/O transmitter unit using a slotted screwdriver.
Example:

x A slave station number is allocated with 8 points. All 4-point and 8-point type units are assigned with one station
number, and a 16-point type unit occupies 2 station numbers. The station number to be set is the first station number.
x 4-point type FP I/O transmitter units use only the first 4 points of the 8 allocated points. The last 4 points cannot
be used.

Notes on station number setting
x Slave station numbers do not have to be set in the order that the units are connected.
x Make sure that the slave station numbers that are being set are not assigned to or occupied by another slave station
of the same input/output type. The same slave station numbers can be used by two units if they are input and output
type units.
Example:
16-input

and Port II.
