Set the method for allocating I/O.
Set to the Configurator as the method for allocating I/O
data in the IN and OUT Areas used by the DeviceNet
Communications Unit. Turn OFF pin 1 of the DIP switch
of the Unit.

Connect the DeviceNet communi-
cations connector.
Connect the DeviceNet communications connector to the
DeviceNet Communications Unit.
Note
Do not turn ON the communications power at this
time.
This power supply is also used as the internal cir-
cuit power supply of the DeviceNet Communica-
tions Unit.

Turn ON the power to the End Unit. Turn ON the power supply connected to the End Unit.
Note
The Temperature Controller will start.

Turn ON the DeviceNet communi-
cations power supply (+V,
−
V)
Turn ON the communications power supply to the
DeviceNet Communications Unit. (See note.)
Note
The DeviceNet Communications Unit will start.

Check the indicators on the
DeviceNet Communications Unit.
Check that the status of each indicator on the DeviceNet
Communications Unit is as follows:
MS: Operating normally when lit green. (When the
power is turned ON for the first time when allo-
cating I/O from the Configurator, the connection
configuration of the Temperature Controllers will
not be registered, so the indicator will flash
green.)
NS: Operating normally when lit green. (DeviceNet
online or communications connected.)
TS: Not lit.

Operate from the Configurator.
(1)
With the Configurator online, register the connec-
tion configuration of the Temperature Controllers in
the Edit Device Parameters Window for the
DeviceNet Communications Unit.
(2)
Use the following method to allocate I/O in the IN
and OUT Areas from the Parameters Window for
the DeviceNet Communications Unit.
a. Select the data to be allocated from the avail-
able allocation data.
b. With the Configurator online, download the data
to the DeviceNet Communications Unit.
(3)
To divide the IN Area used by the DeviceNet Com-
munications Unit into two blocks, select the
DeviceNet Communications Unit in the Edit Device
Parameters Window for the master, and click
Advanced to set the connections.
Dividing the IN Area into two blocks allows, for
example, RUN parameters such as set points (SP)
and process values (PV) to be allocated as DM
words in IN Area 1 and status information to be
allocated as CIO words in IN Area 2.
(4)
When using the Configurator to allocate user-set
I/O, allocate the IN and OUT Areas used by
DeviceNet in the master from the Edit Device
Parameters Window for the master. Click the Mas-
ter I/O Allocations Tab, specify the first words of the
IN Area 1, IN Area 2, and OUT Area 1, and down-
load the parameters to the master.
Note
When fixed allocations are used, I/O is allocated
automatically.
