A K-type PC can be configured with a CPU Unit and one or more of the fol-
lowing Units: Expansion I/O Units, Analog Timer Units, or an I/O Link Unit. All
of these Units are connected in series with the CPU Unit at one end. An I/O
Link Unit, if included, must be on the other end (meaning only one I/O Link
Unit can be used) and an Analog Timer Unit cannot be used. The rest of the
Units can be in any order desired.
There is also a restriction in the number of Units which can be included. To
compute the number of Units for this restriction, add up all of the Units count-
ing the C40K CPU Unit, C60K CPU Unit, C40K Expansion I/O Unit and C60K
Expansion I/O Unit as two Units each and any other Units as one Unit each.
This total must be no more than five.
The following table shows some of the combinations that can be used to
achieve specific numbers of I/O points. The numbers in the table indicate the
number of Units of that size to be used as either the CPU or Expansion I/O
Unit; any one of the Units can be the CPU Unit. This table does not include
the C4P or C16P Expansion I/O Units, the Analog Timer Unit, or the I/O Link
Unit, which can be used for greater system versatility or special applications.
Refer to the remaining tables in this section for other combinations.
