DeviceNet I/O Link Units
Connecting a CPM1A-DRT21 DeviceNet I/O Link Unit (with 32 inputs and 32
outputs as built-in I/O) to function as a slave allows the CP1L to be used as a
DeviceNet slave. A maximum of three DeviceNet I/O Link Units can be con-
nected to the CP1L to create I/O Links for up to 192 points (96 inputs and 96
outputs) between the CP1L and the DeviceNet master.
From the standpoint of the CP1L CPU Unit, the 32 input bits and 32 output
bits allocated to the DeviceNet I/O Link Unit are identical to input and output
bits allocated to Expansion I/O Units even though the DeviceNet I/O Link Unit
does not control external inputs and outputs. The input and output bits allo-
cated to the DeviceNet I/O Link Unit are one side of an I/O link between the
slave CPU Unit and the CP1L CPU Unit to which the Master Unit is con-
nected.
Note
Refer to the
DeviceNet Slaves Operation Manual
(W347) for details on
DeviceNet networks.
