Streamlined Communications from
Temperature Controller to PLC
• The E5ZN Modular Temperature Controller is connected to
the DeviceNet network.
• The I/O link function allows setting and monitoring (e.g., of
present values) for the E5ZN Modular Temperature Controller to
be performed without communications programming.
• Up to 16 E5ZN Modular Temperature Controllers can be con-
nected to one Unit.
• All the parameters for the E5ZN can be uploaded or download-
ed in one operation using DeviceNet Configurator.
Refer to Safety Precautions for All
Temperature Controllers.

Features
Startup Time Is Six Times Faster and No Communications Programs Are Needed
Manage All E5ZN Together from the DeviceNet Configurator
Improved Maintenance with Monitoring, Comment, and Copying Functions
Previously, a time-consuming process of creating
communications programs, debugging, and checking
operations was required for the Temperature Controller to
communicate with the PLC.
● For example, setting 10 Units required 60 minutes.
● Incorrect inputs were a concern.
● Separate debugging for each Unit was needed.
DeviceNet Communications Units enable high-speed data
communications by allocating settings and monitoring
parameters in the PLCs I/O Memory Area, contributing to greater
reductions in the time required for communications program
development.
● For example, set 10 Units in 10 minutes.
● Batch download using the personal computer.
● Debugging is easy using the personal computer.

● Measure the heater control time (RUN
time monitor) to manage heater life
expectancy.
● Monitor supply voltages, such as those
for Temperature Controller and
Communications Unit power supplies,
and network power supplies.
● User-specified names can be set for
each heater and Communications Unit,
enabling the location of errors to be
checked quickly.
● Upload/download Temperature Controller
parameters to the Communications Unit.
This shortens the time required to
replace Temperature Controllers.
