Part Names and Functions Section 3-1
Use the following procedure to operate the front panel DIP switch and perform
copy operations. For details on the copy mode, refer to
Reading/Writing Tem-
perature Controller Settings Using Copy Mode in 8-2-3 Replacing Units .
Copy Mode Setting (Pin 3) Specify the copy mode operation according to the following table.
Note Pins 3 and 6 of the DIP switch are OFF as the factory setting.
Copy Start (Pin 6) The copy operation is performed according to the copy mode set using pin 3,
by operating this pin as follows:
OFF
→
ON (1 s min., 5 s max.)
→
OFF
Note Pins 3 and 6 of the DIP switch are OFF as the factory setting.
I/O Allocations
The Temperature Controller connection configuration and I/O allocations can
be set using simple I/O allocations or I/O allocations from the Configurator.

OFF Setting I/O Allocation from the Configurator.
Use the Configurator to set the DeviceNet Communications
Unit connection configuration and I/O allocation. The settings
are saved in the non-volatile memory in the DeviceNet Com-
munications Unit, so the same settings can be used once they
have been made. (By default, the connection configuration
and I/O allocation are not set.)
ON Simple I/O Allocation Setting
Connection configuration is made and I/O allocation is auto-
matically performed according to the settings made on the
highest communications unit number switch (rotary switch)
and the model switch (DIP switch pin 2).
With the simple I/O allocation setting, the system checks the
communications status of Temperature Controllers up to the
communications unit number set as the highest communica-
tions unit number when the DeviceNet Communications Unit
is started. (Power must also be supplied to the End Unit). As a
result, the Temperature Controllers with which communica-
tions can be performed normally are registered to the connec-
tion configuration. Also, input and output areas are obtained
for Temperature Controllers up to the highest communications
unit number.
