3) I/O allocation method
Described below is the procedure for setting slave station numbers according to the slave station configuration.
<Example>
x The following example is based on the following I/O allocation conditions.
- I/O points: 32 inputs, 32 outputs
- Slot location: the FP3 transmitter master unit is mounted in slot 0 (first I/O No.: 0).
When the above settings are made, X0 to X1F (station Nos. 0 to 3) are allocated for inputs, and Y20 to Y3F (station
Nos. 0 to 3) for outputs. Although the example is based on an input type FP I/O transmitter unit, the procedure
is the same for output type units.
X0 to X7

1. Tentatively allocate I/O numbers to be used, according to the unit type and the number of points of each FP I/O
transmitter unit.
Allocate 8-point I/O numbers even for 4-point type FP I/O transmitter units.

2. Divide the tentatively allocated I/O numbers into groups of 8 points, and give a slave station number to
each group of points in order.

x For example, slave station 2 above is allocated with the following I/O numbers.
x 4-point type units use only the first 4 points of the 8 allocated points. Slave station 1 above uses X0 to X3, while
slave station 3 uses X18 to X1B.
