2.2.3 Configuration of remote I/O communication

The S10VE system can use an RI/O-IF module to perform remote I/O communication on a maximum of two
lines (see Figure 2-3).
The maximum length of each line is 300 m by remote I/O cable alone, extendable to a maximum of 3.3 km
using remote I/O optical adapters. This length of 3.3 km is three optical cables of 1 km each, plus the 300 m
achievable by remote I/O cable.
You can use HSC-1000 and HSC-2100 PI/O units in the same system.
