2-2 Startup Procedure
2-2-1 Simple I/O Allocation
Turn ON pin 1 of the DIP switch on the rear panel of the DeviceNet Communi-
cations Unit. Do not use the Configurator to allocate Temperature Controller
data in the IN and OUT Areas used by the DeviceNet Communications Unit.
(The Configurator is used for user-set allocations in the master.)
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).

10 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
on the rear panel of the Unit. 25
11 Set the highest unit number of the
connected Temperature Control-
lers. Set the highest unit number of the Temperature Control-
lers connected to the DeviceNet Communications Unit
using the rotary switch on the rear panel of the Unit. This
setting will determine the size of the IN and OUT Areas. 25
12 Connect the DeviceNet Communi-
cations Unit to the leftmost Termi-
nal Unit. Align the DeviceNet Communications Unit with the guide
on the E5ZN-SCT24S Terminal Unit on the left of the
block and press in until it clicks into place. 29
13 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.

14 Turn ON the power to the Terminal
Units. Turn ON the power connected to the E5ZN-SCT24S Ter-
minal Units.
Note The Temperature Controllers will start.
30
15 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.

16 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
17 Operate from the Configurator.
(Only when the Configurator is
used to allocate user-set I/O.) 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 word of the
addresses for IN Area 1, IN Area 2, and OUT Area 1,
and download the parameters to the master.
Note When fixed allocations are used, I/O is allocated
automatically.
