3.2 Construction for Network
To construct the network, the parameter setting is to be performed on XSEL PC Software (Note)

Initial setting is to be conducted to all the XSEL controllers connected to IA Net.
(Note) See the instruction manuals of the XSEL PC software for the applicable version.
[1] Setting Procedure
(Preparation) Draw a construction map of the system and make the shared memory allocations
according to the requirements of the system being designed. Draw the
construction map showing the number of units that are connected to IA Net and
the shared memory utilization.
(1) Determine (Note1) the number of input and output signals to have communication among
XSEL.
Write down the numbers of points (16 points per unit) of the input and output signals in the
figure drawn in (Preparation).For the number of input points, write down the numbers
considering the numbers of the input points from XSEL to be referred to and the number of
input points for the extension I/O unit to be referred to.
(2) Determine (Note1) the number of points for the output signals of the extension I/O unit that
each XSEL requires.
At the bottom of each XSEL drawn in the diagram in (Preparation), put the number of output
(16 points) used for the extension I/O unit.
The maximum number of the output points should be the total number of output ports on the
I/O boards (four at max.) mounted on the extension I/O unit.
