Section 3-1
For details on
setting I/O allocations from the Configurator and simple I/O allocations,
refer to
SECTION 4 Remote I/O Communications
.
Model Setting (DIP Switch
Pin 2)
Set the model of the Temperature Controllers to be connected to the
DeviceNet Communications Unit. This setting is enabled if DIP switch pin 1 is
set to ON (simple I/O allocations).
Note
1.
Refer to page 64 and page 68 for information on data allocations when
both TC2 and TC4 Units are connected to a DeviceNet Communications
Unit.
2.
Always turn OFF the DeviceNet communications power supply and turn
OFF the End Unit power supply before making this setting.
3.
When DIP switch pin 1 is set to OFF (I/O allocations with Configurator), the
MS indicator will flash green if the connection configuration is not regis-
tered. When the connection configuration is set from the Configurator, the
DeviceNet Communications Unit will automatically be reset, and after
starting normally, the MS indicator will be lit green.
4.
By default, DIP switch pins 1 and 2 are set to OFF.
Setting the Highest
Communications Unit
Number
Use this switch to set the highest communications unit number (0 to F: 0 to 15
decimal) of the connected Temperature Controllers. This setting is enabled
only when DIP switch pin 1 is set to ON (simple I/O allocations). Set the com-
munications unit numbers on the other Temperature Controllers using the fol-
lowing settings 0 to F (0 to 15 decimal).

Setting Communications Unit Number Switch for Temperature Controllers
Note
1.
Refer to the
EJ1 Modular Temperature Controller User’s Manual
(Cat. No.
H142
) for details.
2.
Always turn OFF the DeviceNet communications power supply and turn
OFF the End Unit power supply before making this setting.
3.
Always set the communications unit number for each Temperature Control-
ler to between 0 and F (0 and 15 decimal).
4.
If simple I/O allocations are used, do not use a Temperature Controller that
has a communications number higher than the highest communications
number set here.
5.
I/O data is also allocated automatically according to this setting.
6.
The default setting is 1.
