In the diagram below, a C20 CPU, a C40P CPU, a C20 I/O Unit and two I/O
Link Units can exchange data over a distance with a C500 Remote I/O Mas-
ter Unit. The C20 I/O Link Unit is set for IR 28 (which accesses IR 29 as
well), and the C40P I/O Link Unit is set for IR 30 (which accesses IR 31 as
well). The C40P I/O Link Unit is also set as the terminator.

When setting the I/O Link Unit, in this example, it is necessary to take into
account not only the I/O words of the C500 Remote I/O Master Unit, but also
those of the C20 CPU and the C40P CPU.
