CPM1A-DRT21 DeviceNet I/O Link Unit
(1)
DeviceNet Communications Connector
Used to connect DeviceNet communications. For the wiring, use the con-
nector provided with the CPM1A-DRT21 or use a connector purchased
separately.
(2)
Rotary Switches (SW2, SW3)
Used to set DeviceNet node numbers.
(3)
DIP Switch (SW1)
Used to set the DeviceNet baud rate and the output hold function.
Note
When using Expansion Unit/Expansion I/O Unit Error Flags (A436)
in the program, set pin 4 on the DIP switch to ON. If communica-
tions are set to be cleared, the timing for clearing outputs and set-
ting the Error Flags may not agree.
