Written by

Omron E5CC Temperature Controller is one of the most used devices in factories, it supports most thermocouple types and is very high quality, it also supports RS485 communication port suitable for communicate with peripheral devices.

Today will guide you to use Labview to connect the controller and read the temperature from the E5CC, making it easy to collect and store the temperature from the E5CC.
