Why are communications not possible with my Omron Controller?
- M
  Melinda BryantAug 28, 2025
  Communications issues with your Omron Controller may arise if a non-recommended adapter is being used. Ensure that the connected device is not faulty.

Why aren't the set points or RUN/STOP status changing for slaves on my Omron E5EC Temperature Controller?
- D
  Dan FlynnAug 27, 2025
  If the set points or the RUN/STOP status will not change for any of the slaves, check that: * The wiring to the master (i.e., the Controller with communications unit number 0) is not correct. * The communications settings in the master are not correct.

Why can't I always change set points on my Omron Temperature Controller?
- M
  Melanie BeckAug 26, 2025
  If it's sometimes not possible to change the set points or RUN/STOP status on your Omron Temperature Controller, there may be noise interference. Connect terminating resistance to both ends of the communications line.

How to prevent Omron Temperature Controller communication data corruption due to environmental noise?
- R
  Richard YoungAug 26, 2025
  If the communications data is being corrupted by noise, try using a slower baud rate. Also, separate the communications cable from the source of the noise.

How to fix a large temperature error (S.Err display) on my Omron E5EC?
- A
  Antonio PetersonAug 25, 2025
  A large temperature error or an input error (S.Err display) on your Omron Temperature Controller can be caused by an input type mismatch. Check the sensor type and reset the input type correctly. It can also be caused by the thermometer not being installed properly. Check the thermometer installation location and polarity and install correctly.
