Omron E5ZN-DRT User Manual
DeviceNet Communications Unit
E5ZN-DRT
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 connected to one Unit.
• All the parameters for the E5ZN can be uploaded or downloaded 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
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.

Improved Maintenance with Monitoring, Comment, and Copying Functions
● 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.
Check the settings
for the heater of
oven No. 3.
