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

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.
