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 plc247.com 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.
Computer & Omron E5CC “Wiring Diagram”
Note: If the communication distance is long, you need to use a 120Ω terminal resistor.
E5CC Modbus RTU Parameters Setting
Here are the communication parameters to be installed for the E5CC (You can watch the video below for details)
Registers Address Table
+ Temperature Setting Address = 2103 (hex) = 8451 (dec)
+ Temperature Present Address = 2000 (hex) = 8192 (dec)

Hi, Can you send me download link of Labview software
you can download on Labview main page
Hi…
I need help to make programming support for LabVIEW via Omron CP2E plc by Modbus RTU or Modbus TCP..
Thank you very much.
i will make tutorial when i have time sir
I programmed the temp monitor the same as described above.
but I was monitoring the Liquid N2 (-temp) Using the Pt sensor, and it did not work as (+Temps).
is that the Temperature Setting Address should be changed according to the Pt sensor?
sent to me model sensor
Pt100 temp sensor
need module pt100
PT100Ω -200°C-850°C connect to Omron E5CC (connection is the same as the one described above).
You need to connect the PT100 to a Modbus-enabled controller
problem is solved.
Modbus Read register value type U16. it has to change I16 value type.
yes sir
Hi, Can you a tutorial for a Omega CN400 controller?
I will upload tutorial when i have it
Can you please make your LabView VI available for download? You must be using a different version of NI Modbus library as I can’t seem to make this work with the latest Modbus package from NI.
you need add module Modbus sir
