9.3.6 Remote I/O optical adapter connection setting

You can extend the length of remote I/O lines to a maximum of 3.3 km by connecting remote I/O optical
adapters (model: LQZ410) to the remote I/O lines of the RI/O-IF module.
- When connecting a remote I/O optical adapter, specify Connect.
- When not connecting a remote I/O optical adapter, specify No-connect.
■ How to set whether an optical adapter is connected
For details on the setting to make when connecting an optical adapter, see the S10VE Software Manual
Operation Ladder Diagram System for Windows® (manual number SEE-3-131).

9.3.7 Remote I/O point setting

The remote I/O function can handle a maximum of 2,048 input points and 2,048 output points. However, if
you only intend to use a small number of I/O points, scanning all 2,048 points makes each communication
operation take longer, and timeouts occur in relation to unallocated I/O numbers. This extends communication
time by an amount equivalent to the time required to detect these timeouts.
For this reason, a number of tiers are defined for remote I/O points that allow you to select a smaller number
when applicable. By selecting the smallest number of points that meets your needs, you can reduce
communication time and operate an efficient system.
■ Setting the number of remote I/O points
For details on how to set the number of remote I/O points, see the S10VE Software Manual Operation Ladder
Diagram System for Windows® (manual number SEE-3-131).
Note: When an I/O unit is connected to RI/O-2 (line 2), you must select 1,536 or 2,048.
The 64 and 1,024 settings only work with RI/O-1 (line 1).
