1-1
DeviceNet
DeviceNet (CompoBus/D) is a multi
-
vendor, open
-
field network that combines
control and information at the machine and line control level. The E5ZE Multi-
point Temperature Controller with DeviceNet communications supports the
following transmission services.
• Remote I/O
• DeviceNet explicit message communications
For details on the methods for connecting and configuring a DeviceNet net-
work, refer to the DeviceNet (CompoBus/D) Operation Manual (Cat. No.
W267).
This part of the manual describes mainly how to operate the E5ZE as a Slave
in a DeviceNet network. It is assumed that the E5ZE is connected to an

Remote I/O
The remote I/O function allows I/O data to be exchanged automatically
between the DeviceNet Master Unit and the E5ZE, without the need of any
special programs. The remote I/O function enables the following functions in
the E5ZE.
• Reading the process value and different operating statuses.
• Writing set points.
• Executing commands to start and stop temperature control.

DeviceNet Explicit Message Communications
DeviceNet explicit messages are used to read and write messages for Slaves,
and perform various control operations, according to the program being used
by the host system. DeviceNet explicit message communications enable the
following functions in the E5ZE.
• Reading and writing set values and process values.
•
Starting and stopping auto
-
tuning (AT), and other operating directions.
