7.7.3 Examples of cable wiring
(1) When connecting cables with different characteristics to the RI/O-1 and RI/O-2 ports
Figure 7-16 shows a wiring example for a scenario in which cables with different characteristics connect
to the RI/O-1 port and RI/O-2 port of the CPU module.
- For details on how to set the terminating resistance, see
7.7.4 Setting terminating resistance

Note: For the actual RI/O-IF module and remote I/O station module, cables
cannot be attached on the terminal block from the right side.
The following figure shows cables attached from the right to make
the wiring easier to understand.
