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.
