Connecting Temperature Controllers
Section 1-3
Note
There is no priority between operation commands and settings for DeviceNet
communications from the master, and operation commands and settings from
the Configurator. Do not change the same data or send different operation
commands more than one source at the same time.
1-3-2
Temperature Controller Communications
The DeviceNet Communications Unit communicates through port B on the
Temperature Controllers. The DeviceNet Communications Unit will automati-
cally set the communications settings. You do not need to set them. If you
mistakenly change the settings, use the CX-Thermo to restore the default set-
tings and then reset the DeviceNet Communications Unit.
1-3-3
Temperature Controller Models
Refer to
EJ1 Temperature Controllers
on page 171 for information on the
Temperature Controller models.
1-3-4
Temperature Controller Power Supply
Power is supplied to the Temperature Controllers through the End Unit. For
details, refer to the
EJ1 Modular Temperature Controller User's Manual
(Cat.
No. H142).
1-3-5
Temperature Controller Registration
The connected Temperature Controllers must be registered in the configura-
tion in the DeviceNet Communications Unit. The DeviceNet Communications
Unit automatically verifies that the registered the Temperature Controllers
match the Temperature Controllers currently able to communicate. If the unit
numbers do not match in the verification process, the Temperature Controllers
will be determined to have an error, causing the following status.
• The TS indicator will flash red.
• The Communicating Flag will turn OFF and the Communications Error
Flag will turn ON for each Temperature Controller that is not communicat-
ing but is registered as being connected to the DeviceNet Communica-
tions Unit.
The method used to register the connection configuration depends on the
method of remote I/O allocation.

1.
Allocation from the Configurator
With DIP switch pin 1 set to OFF, turn ON the power supply, and register
the configuration using the Configurator or an explicit message.
2.
Allocation Using Simple Allocation
Turn DIP switch pin 1 to ON, set DIP switch pin 2 to the model to be con-
nected, and set the highest communications unit number setting to the
highest communications unit number of the Temperature Controllers that
are connected.
