I/O Allocation for CPM1/CPM1A/CPM2A PCs

5-2-4 Examples of Expansion Unit and Expansion I/O Unit Allocation

n: "n" denotes the last output word allocated to the CPU Unit, or to the pre-
vious Expansion Unit or Expansion I/O Unit if one is already connected.
2. Only CPM1 CPU Units with the "-V1" suffix can have 3 Analog I/O Units con-
nected. CPU Units without the "-V1" suffix can only have one Analog I/O Unit
connected.
3. Only one CPM1A-TS002/102 Temperature Sensor Unit can be connected
to the PC. If a CPM1A-TS002/102 Temperature Sensor Unit is connected to
the PC, one more Expansion Unit (other than another CPM1A-TS002/102
Temperature Sensor Unit) or Expansion I/O Unit can be connected.
Analog I/O Unit
Temperature Sensor Units
CPM1A-TS001/TS101
2 temperature inputs
Input 0: word (m+1)
Input 1: word (m+2)
CompoBus/S I/O Link Unit and DeviceNet I/O Link Unit
CPM1A-SRT21
8 bits
Input: word (m+1)
8 bits
Output: word (n+1)
Note Input bits 00 to 07 in word (m+1) are for outputs from the Master. Output bits 00 to
07 in word (n+1), are for inputs to the Master.
When using a CPM1 CPU Unit without "-V1" at the end of the model number,
only one Expansion I/O Unit can be connected.
When using a CPM1 CPU Unit with "-V1" at the end of the model number, up to
3 CPM1A-series Expansion I/O Units can be connected.
When using a CPM1A CPU Unit with 30 or 40 I/O points, or when using a
CPM2A CPU Unit, up to 3 Expansion Units or Expansion I/O Units, excluding
4-input Temperature Sensor Units, can be connected. Only one 4-input Tem-
perature Sensor Unit can be connected. If a 4-input Temperature Sensor Unit
is connected to the PC, only one more Expansion Unit (except for another
4-input Temperature Sensor Unit) or Expansion I/O Unit can be connected.
CPM1A-MAD01/MAD11
2 analog inputs
Input 0: word (m+1)
Input 1: word (m+2)
1 analog output
Output 0: word (n+1)
No outputs
