E5ZN-DRT

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.

to enable immediate execution.

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.
