Note Establishing the resizing station number and final station number parameters will speed up
networked communication, as unused stations are skipped in the communications polling.
[Setting 2: Setting of Resizing Station Number and Final Station Number]

Set the resizing station number (settable range from 0 to 63) to I/O Parameter No.603.
(Set the top station number of the first XSEL controller unit.)
Set the final station number (settable range from 1 to 63) to I/O Parameter No. 604.
(Set the top station number of the last networked device.)
Shown below is an example for setting (when connecting four units of XSEL).

[Caution in Setting]
1 For I/O Parameters No.603 and 604, set the same values in common for all the XSEL
controllers. If not the same value, “548: IA Net Resizing Overlapping Error” will be
generated.
2 When a change is made to a value in I/O Parameters No. 603 or 604, it is necessary
to either cold reboot (power cycle) all networked IA Net devices (all networked
controllers) or perform a simultaneous software reset on all controllers.
