The basic operating procedure is shown below. For details about settings and
connections, refer to DeviceNet Operation Manual (W267). For explanations
about Slave Units, refer to SECTION 4 Basic I/O Unit Specifications and SEC-
TION 5 Special I/O Unit Specifications.
Inputs: Number of points/input type/connection type
Outputs: Number of points/input type/connection type

The combined total of input points and output points for each Communications Unit is 1,024 max.
The total current supplied from the Communications Unit to each I/O Unit (I/O Unit interface current
consumption) is 0.4 A max.
Mount Units on DIN track (DIN 35-mm track: all Units).
Connect I/O Unit Connecting Cabled and end connector.
Connect Communications Unit internal power supply (24 VDC 15%/+10%).
Connect I/O power supply (24 VDC 15%/+10%) for each Transistor Input/Output Unit and Relay
Output Unit.
Connect I/O power supply (24 VDC 15%/+10%) for each Analog Input/Output Unit and
Temperature Input Unit, as well as power supply for each Counter Unit encoder, using a separate
power supply from the above.
Connect I/O to each I/O Unit.
Set the node number of the Communications Unit as a DeviceNet Slave, and the hold/clear output
settings for the baud rate and communications errors.
Set the Analog Input Unit, Analog Output Unit, and Temperature Input Unit ranges and other
specifications. (When setting the Analog Input Unit, Analog Output Unit, and Temperature Input
Unit ranges from the Configurator, set the DIP switch to Software Setting Enable.)
Connect the Communications Unit to the DeviceNet Master Unit using the DeviceNet
Communications Cable.
Turn ON the PC power supply.
Turn ON the DeviceNet communications power supply.
Turn ON the Communications Unit internal power supply.
Turn ON the I/O power supply to individual I/O Units.
Set as required for the Communications Unit, Analog Input Units, Analog Output Units, and
Temperature Input Units using the DeviceNet Configurator (versions 1.11 and later).
Set to enable the DeviceNet Master Unit scan list (from a PC Peripheral Device or
the Configurator).
Check the I/O Unit interface status.
Check the indicators on all Units.
The following indications are normal:
Communications Unit MS indicator: Lit green
Communications Unit NS indicator: Lit green
TS indicators for I/O Units:
Check that the data for the I/O words allocated in the I/O memory (with default allocations, in the
DeviceNet area) of the CPU Unit of the PC is being correctly read and written by the CPU Unit.
