Connecting Temperature Controllers
1-3-1
Temperature Controller ID and Number of Connectable Units
A DeviceNet Communications Unit is connected as shown in the following dia-
gram.
The DeviceNet Communications Unit differentiates each of the connected
Temperature Controllers according to communications unit numbers (0 to F: 0
to 15 decimal). The Temperature Controllers can be connected in any order.
The communications unit number of each Temperature Controller is set using
the rotary switch on the front panel of the Temperature Controller. Always set
a unique communications unit number for each Temperature Controller.
Up to 15 Temperature Controllers can be connected side by side. By using an
End Unit, however, up to 16 Temperature Controller can be connected using
distributed placement.
