Section 1-2
Note
1.
When a CS/CJ-series DeviceNet Unit is used as the master, two blocks
can be used for the IN Area (the connections can also be set). When a
CVM1, CV-series, or C200HX/HG/HE DeviceNet Master Unit is used, the
IN Area must be in 1 block, and up to 100 words (200 bytes) are allocated.
(Only polling connections can be used.)
2.
When a CVM1, CV-series, or C200HX/HG/HE DeviceNet Master Unit is
used, up to 32 words can be allocated in the master for a single node.
3.
The set points, alarm setting values, PID constants, and other Tempera-
ture Controller parameters can be set together.

Note
Up to 15 Units can be connected side by side. The 16th Unit is connected
using distributed placement by using an End Unit.
Applicable Temperature Control-
lers
(TC4)
• EJ1N-TC4A-QQ
• EJ1N-TC4B-QQ
(TC2)
• EJ1N-TC2A-QNHB
• EJ1N-TC2B-QNHB
• EJ1N-TC2A-CNB
• EJ1N-TC2B-CNB
Power supply
Power is supplied via the terminal block of the End Unit (power supply for communi-
cations between the DeviceNet Communications Unit and Temperature Controllers
and power supply for internal circuits of the Temperature Controllers).
Copying
The parameters of a connected Temperature Controller can be uploaded or down-
loaded as a batch by using the DeviceNet Communications Unit’s DIP switch or an
explicit message. The bank, G3ZA, and G3PW parameters are not copied.
The uploaded parameters are stored in the DeviceNet Communications Unit.
