It interfaces the Series 16/18 with the machine when connected to the
control unit of the Series 15–B control unit via the I/O Link. One I/O unit
can be configured by mounting the I/O modules required for either the 5–
or 10–slot base unit. A variety of I/O modules are provided so appropriate
modules can be selected according to the use, points, voltage level,
current capacity, and signal specifications. See Section 6.3.9 for further
