Startup Procedure
2-2-1
Simple I/O Allocation
Use this method in the following situations.
• To allocate words in the master only for basic data, such as the set points
(SPs), process values (PVs), and alarm outputs for each Temperature
Controller.
• To use the DeviceNet Communications Unit without a Configurator (when
allocating only fixed I/O in the master).

Set the I/O allocation method.
Set simple I/O allocation as the method for allocating I/O
data in the IN and OUT Areas used by the DeviceNet
Communications Unit. Turn ON pin 1 of the DIP switch.
Set DIP switch pin 2 to the model of the Temperature
Controller connected.
25
9
Set the highest unit number of the
connected Temperature Control-
lers.
Set the highest communications unit number of the Tem-
perature Controllers connected to the DeviceNet Com-
munications Unit using the rotary switch (Max. No.) of
the Unit. This setting will determine the size of the IN and
OUT Areas.
26
10
Connect the DeviceNet communi-
cations connectors.
Connect the DeviceNet communications connector to the
DeviceNet Communications Unit.
Note
Do not turn ON the communications power sup-
ply at this time.
This power supply is also used as the internal cir-
cuit power supply of the DeviceNet Communica-
tions Unit.
32
11
Turn ON the power to the End Unit. Turn ON the power connected to the End Unit.
Note
The Temperature Controllers will start.

12
Turn ON the DeviceNet communi-
cations power
(V+, V
−
).
Turn ON the communications power supply to the
DeviceNet Communications Unit. (See note.)
Note
The DeviceNet Communications Unit will start.
---
13
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.
NS: Operating normally when lit green. (DeviceNet
online or communications connected)
TS:
Communicating with Temperature Controllers
when lit green.
23
14
Operate from the Configurator (if
user-set allocation is used at the
master).
Note
This also applies if 11 or
more TC4 Units are con-
nected.
With the Configurator online, open the master's Edit
Device Parameters Window and allocate the IN and OUT
Areas used by DeviceNet in the master. Click the Master
I/O Allocations Tab, specify the first words for allocation
input 1 and allocation output 1, and download the param-
eters to the master.
Note
When fixed allocations are used, I/O is allocated
automatically.
