Bits
Only one 4-input Temperature Sensor Unit (CPM1A-TS002/102) can be con-
nected to the PC. The CPM1A-TS002/102 can, however, be connected together
with an Expansion I/O Unit or a different Expansion Unit.

Note
1. The values for the maximum number of I/O in the above table include the I/O
on Expansion I/O Units.
2. Although only up to 5 Expansion Units or Expansion I/O Units can be con-
nected to a CPM2C PC, no more than 10 input words and 10 output words
can be allocated.
